ROHM’s New LDO Regulators with 500mA Output Current Achieving Stable Operation Even with Ultra-small Capacitors to Expand Design Flexibility for High-current Applications

　　ROHM has developed the “BD9xxN5 Series” of LDO regulator ICs with 500mA output current, featuring its proprietary ultra-stable control technology “Nano Cap™”. This series comprises 18 products designed for 12V/24V primary power supply applications used in automotive equipment, industrial equipment, and communication infrastructure.　　In recent years, electronic devices have demanded higher density in smaller form factors at the same time. To meet this demand and achieve space savings and design flexibility, power supply ICs must be capable of stable operation even with small-capacity capacitors. However, achieving such performance with output capacitors of 1µF or less has been technically difficult.　　To address this challenge, ROHM developed the “BD9xxN1 Series” LDO regulator (150mA output current) in 2022, incorporating its proprietary ultra-stable control technology, “Nano Cap™”. This innovation enables stable operation with output capacitors as small as 100nF, earning widespread adoption across numerous applications.　　The newly developed BD9xxN5 Series builds on the success of the BD9xxN1 Series by increasing the output current to 500mA – more than three times higher than before – significantly broadening its suitability for applications requiring higher power. In addition, very low output voltage ripple of approximately 250mV (with load current variation of 1mA to 500mA within 1µs) is achieved with a small output capacitance of just 470nF (typical). Beyond standard small MLCCs (multi-layer ceramic capacitors) in the range of several µF and large-capacity electrolytic capacitors, it also supports ultra-small MLCCs, such as the 0603M size (0.6mm × 0.3mm), with capacities below 1µF – where stability was previously difficult to achieve. This contributes to space saving as well as greater flexibility in component selection.　　Furthermore, high-precision SPICE models, “ROHM Real Model” are provided for accurate simulation and can be downloaded from the ROHM official website.　　SPICE Models: BD900N5xxx-C BD933N5xxxx-C BD950N5xxxx-C　　ROHM will continue to contribute to the high performance, miniaturization, and high reliability of electronic devices by further expanding its Nano Cap™ technology-equipped LDO series.　　Application Examples　　Automotive Equipment　　● Powertrain system power supplies for fuel injection systems (FI) and tire pressure monitoring systems (TPMS)● Body system power supplies for body control modules (BCM)● Infotainment system power supplies for clusters ad head-up displays (HUD), etc.Industrial Equipment　　● Power supplies for controllers like Programmable Logic Controllers (PLC), Remote Terminal Units (RTU), and industrial gateways● High-precision LDOs for analog loads and sensors measuring temperature, pressure, flow rate, etc.● Power supplies for monitoring and control panels in disaster prevention systems, access control systems and building automation.● Standby power supplies for Human-Machine Interfaces (HMI) and panel equipment, etc.Consumer Electronics　　● Power supplies for control boards in refrigerators, dishwashers, air conditioners, etc.● Power supplies for home appliances like thermostats and doorbells● Power supplies for constant power applications in home security and network equipment, etc.　　What is Nano Cap™ Technology?　　Nano Cap™ refers to ultra-stable control technology achieved by combining advanced analog expertise covering circuit design, processes, and layout utilizing ROHM’s vertically integrated production system. Stable control eliminates the problem of unstable operation related to capacitors in analog circuits, contributing to a reduction in design resources for a wide range of applications in automotive, industrial equipment, consumer, and other fields.　　Terminology　　Primary　　In a power supply circuit, the side in charge of 1st stage conversion from a power source such as a battery is called the primary and the side responsible for 2nd stage conversion is referred to as the secondary.　　LDO Regulator (Low Drop Out Regulator / Low Saturation Regulator)　　A type of power supply IC that converts between two different DC voltage levels. Falls under the category of linear regulator (where the input/output voltages operate linearly) characterized by a small input-output voltage difference. Compared to DC-DC converter ICs (switching regulators), LDOs feature a simpler circuit configuration and lower noise.　　ROHM Real Model　　A high-accuracy simulation model that make it possible to also achieve a perfect match between the actual IC and simulation values utilizing ROHM’s proprietary model-based technology.

Panasonic Industry Commercializes Conductive Polymer Tantalum Solid Capacitors (POSCAP) with The Industry's Lowest Profile*1 to Support High-Output Power Delivery Required for USB Type-C Connections

　　Panasonic Industry Co., Ltd., a Panasonic Group company, announced  that it will begin commercial production of its two models of Conductive Polymer Tantalum Solid Capacitors (POSCAP), 50TQT33M and 63TQT22M. These capacitors are incorporated into power circuits used for information and communication equipment, including laptops and tablets. They offer an ultra-high withstand voltage and high capacitance in a body with the industry’s lowest profile of 3 mm, supporting high-output power delivery through USB Type-C connectors. Mass production for these models is planned to start in December 2025.　　These capacitors are ideal for voltage stabilization and noise reduction in power supplies compliant with USB Power Delivery (USB-PD)[1] 3.1. While previous USB-C connectors supplied up to 100 W (20 V/5 A), USB-PD 3.1 expands this to 240 W (48 V/5 A). This enables widespread use of USB-C connectors for high-speed data transfer and rapid charging, and is expected to further expand applications to larger equipment requiring high power output, such as displays.　　On the other hand, information and communication equipment such as laptops are increasingly required to be thinner and more compact. Capacitors therefore must combine an ultra-high withstand voltage, high capacitance, and a low profile in order to fit into limited space. Panasonic Industry began mass production of Conductive Polymer Tantalum Solid Capacitors (POSCAP) in 1997 and, as an industry leader, has continuously delivered first-of-their-kind products. Leveraging proprietary powder molding technology and film formation technologies, the company has newly developed two models that achieve both an ultra-high withstand voltage and high capacitance in a package with the industry's lowest profile of 3 mm.　　Through these unique device technologies, Panasonic Industry will continue to contribute to enhancing the functionality of electronic equipment, including laptops, while also reducing the environmental impact through smaller, lighter devices and lower material usage.　　Key features:　　1. Achieves both an ultra-high withstand voltage and high capacitance*2 to support high-output USB Type-C power delivery, in a 3 mm profile—the lowest in the industry*1—enabled by proprietary powder molding and film formation technologies　　2. Lineup of USB-PD 3.1-compliant models rated at 50 V and 63 V　　3.

Achieves both an ultra-high withstand voltage and high capacitance to support high-output USB Type-C power delivery, in a 3 mm profile—the lowest in the industry—enabled by proprietary powder molding and film formation technologies　　To achieve capacitor performance required for USB-PD 3.1 power supplies in a low-profile body, both high capacitance and a high withstand voltage must be ensured, despite their trade-off relationship. High-capacitance tantalum powder is necessary for electrode materials, but its fine particle size makes molding difficult, creating challenges for stable production. Forming a uniform dielectric film on the surface of the electrodes is important for enhancing the withstand voltage. However, since electrodes made with high-capacitance tantalum powder contain extremely small internal pores, dielectric oxide films tend to develop imperfections.　　Panasonic Industry overcame these challenges by establishing proprietary technology to mold high-capacitance tantalum powder with uniform density, and by optimizing the film deposition process to create flawless dielectric films. This enabled the development of two new models that combine an ultra-high withstand voltage and high capacitance, meeting the USB-C high-output power delivery requirements in a 3 mm low-profile package.Cross-sectional view of POSCAP and enlarged view of the inside of the electrode body　　2. Lineup of USB-PD 3.1-compliant models rated at 50 V and 63 V　　Until now, Panasonic Industry’s POSCAP lineup extended only up to 35 V, with no models compatible with USB-PD 3.1, which extends the rated voltage specification to 36 V (180 W) and 48 V (240 W). The two new models, rated at 50 V and 63 V, each achieve a high capacitance of 22 μF or higher in a package with the industry's lowest profile of 3 mm. The full lineup provides flexibility to meet diverse applications and equipment specifications.　　3. Contributes to reduced material usage lower environmental impact through low-profile design　　Compared to the industry standard size*3, the new models reduce volume by 25%, contributing to a lower environmental impact through reduced material usage.　　*3 Comparison with the industry standard size (7.3 mm × 4.3 mm × 4 mm) of conductive polymer tantalum solid capacitors used in USB-PD 3.1 compliant power suppliesApplications:　　Voltage stabilization and noise reduction of USB-PD 3.1-compliant power supplies for laptops, displays, and peripheral equipment　　Arc discharge[2] countermeasures for USB-PD 3.1-compliant connectors　　Specifications:　　Life: 2,000 hours at 105°C; guaranteed operating temperature range: -55°C to 105°C　　Ripple current[3]: 100 kHz, 105°C　　ESR[4]: 100 kHz, 20°C　　*4 Product dimensional tolerance:　　Length (L): ±0.3 mm; Width (W): ±0.2 mm; Height (H): ±0.2 mmTerm descriptions:　　[1] USB-PD　　The power delivery standards established by the standard-setting organization USB Implementers Forum, Inc.

How to Discharge a Capacitor : A Step-by-Step Guide

　　Capacitors are essential components in electronic circuits, storing electrical energy for later use. However, when working with capacitors, it’s crucial to handle them properly to ensure safety and prevent damage. One important aspect of working with capacitors is “How to Discharge a Capacitor”. In this guide, we’ll walk you through the steps to safely discharge a capacitor, why it’s necessary, and the precautions you should take.　　What is capacitors?Before diving into the discharge process, it’s helpful to understand what capacitors are and how they function. A capacitor is an electrical component that stores and releases energy in the form of an electric charge. It consists of two conductive plates separated by an insulating material called a dielectric. When a capacitor is charged, it holds a voltage difference between its plates, which can persist even after power is disconnected.　　Why Discharge a Capacitor?1. Safety: Capacitors can retain a significant amount of charge even after the power is turned off. Discharging a capacitor is crucial to avoid electric shocks or damage to electronic components.　　2. Maintenance and Repair: When servicing electronic devices, discharging capacitors ensures that there are no residual charges that could interfere with repairs or adjustments.　　3. Circuit Design: In some cases, you might need to discharge a capacitor to reset or test electronic circuits.　　How to discharge a capacitor?1. Safety First: Power Off the Device　　– Unplug the Device: Ensure the device or circuit is completely disconnected from the power source. This is the most critical step in preventing electrical shocks.　　– Wait for a Safe Period: Even after disconnecting power, give the capacitor some time to self-discharge. However, don’t rely solely on this; always use proper discharge methods.　　2. Use Proper Discharge Tools　　– Discharge Tool: For high-voltage capacitors, it’s advisable to use a dedicated capacitor discharge tool, which often includes a resistor to safely dissipate the charge.　　– Insulated Tools: For lower-voltage capacitors, you can use insulated screwdrivers or pliers.　　3. Discharge Process　　– Connect the Discharge Tool: If using a discharge tool with a resistor, connect it across the capacitor’s terminals. If using a screwdriver, carefully touch the insulated handle to both terminals, ensuring you don’t touch the metal parts directly.　　– Hold for a Few Seconds: Allow the tool to stay in contact with the terminals for several seconds to ensure the capacitor is fully discharged.　　4. Verify the Capacitor is Discharged　　– Use a Multimeter: To confirm that the capacitor is completely discharged, use a multimeter to check the voltage across the terminals. A reading close to 0 volts indicates that the capacitor is safe to handle.　　5. Dispose of or Store Safely　　– Handling: Once discharged, handle the capacitor with care. If it’s to be reused, store it in a safe location where it won’t accidentally get recharged or come into contact with conductive materials.　　– Disposal: If you need to dispose of the capacitor, follow local electronic waste disposal regulations to ensure environmentally responsible handling.　　Precautions　　– Never Short the Terminals Directly: Directly shorting the capacitor terminals with a metal object can cause sparks, heat, and potential damage.　　– Use Insulated Equipment: Always use tools with proper insulation to avoid accidental electric shocks.　　– Handle with Care: Even discharged capacitors can have residual charges. Handle them carefully to avoid any accidental charge buildup.　　ConclusionDischarging a capacitor is a straightforward but essential task when working with electronic devices. By following these steps and taking the necessary precautions, you can ensure both your safety and the proper functioning of your electronic components. Always prioritize safety and use the appropriate tools to handle capacitors effectively. With these practices, you’ll be better equipped to handle capacitors in various electronic applications.

Why use tantalum <span style='color:red'>capacitor</span>s in circuit board assembly
Trade news

Why use tantalum capacitors in circuit board assembly

　　A capacitor is a component made up of two metal films placed close together and separated by an insulating material. The two pieces of metal are called pole plates, and the material in between is called the dielectric. The key reason why capacitors can be divided into different types is that there are certain differences. There are many differences not only in materials, but even in design principles, working principles and structures.　　Tantalum is the second most precious metal after precious metals, and is one of the most expensive of the rare metals. Tantalum capacitors are electronic components with tantalum as the main component, small in size and high in capacity, installed on printed circuit boards of many small electrical/electronic devices such as personal computers, cell phones and digital.　　What is tantalum capacitor　　Electrolytic capacitors with tantalum as a component are called tantalum capacitors. They are polarized capacitors with good frequency and stability. It has a tantalum anode and electrolytic capacitor.　　Tantalum capacitors have been used in electronic circuits since the 1950’s. Today they still play an important role in many different types of electronics.　　Tantalum capacitors are a kind of electronic components which is widely used in the industries. They can be found in every electronic product such as speakers and cell phones, TV and microwave oven, computer and headphone.　　What is a tantalum capacitor used for　　Tantalum capacitors are small, high-capacity capacitors. Tantalum capacitors come in various shapes and are made into small and chip components suitable for surface mounting. Tantalum capacitors are used not only in military communications, but also in aviation, aerospace and other fields, and are widely used in industrial control and vision, in frequency equipment, communication instruments and other products.　　Due to the thin oxide film, the distance between the two pole plates of tantalum capacitors is very close, and there is almost no inductive reactance, which is very sensitive, so the charging and discharging speed is very fast. In addition, because there is no electrolyte inside the tantalum capacitor, it is very suitable for working under high temperature.　　Tantalum capacitors are used in many different applications, including:　　●Power supplies and inverters　　●Radio frequency systems　　●Telecommunications equipment　　●Scientific instrumentation equipment (e.g., oscilloscopes)　　What are the pros and cons of tantalum capacitors　　Tantalum capacitors are a good choice for electronic applications. They are used in power supplies and other low-power devices, as they provide high capacitance while maintaining low leakage currents. They also have excellent ESR (equivalent series resistance), which means that they can withstand high voltages without affecting their performance.　　Pros　　Tantalum capacitors have several advantages over traditional aluminum electrolytic capacitors:　　●Tantalum has better conductivity than aluminum, making it ideal for applications where heat dissipation is important (such as switching power supplies).　　●It has lower drift rate than aluminum due to its higher dielectric constants (dielectric constant is the property of an insulating material that determines how easily electricity flows through it).　　●You can use tantalum capacitors with no risk of arcing or explosions because there’s no need for venting holes on them—and if you do want one then you’ll be able to find one at any electronics store!　　Cons　　There are some disadvantages of tantalum capacitors:　　●Tantalum capacitors are more expensive than ceramic capacitors, and they can be up to twice as expensive as aluminum electrolytic capacitors.　　●It takes time for the capacitor to break in and get its full potential.　　What are the features of tantalum capacitor　　The Reliability:　　Tantalum capacitors are reliable, and they have a longer service life than other types of capacitors. They have high current handling capability with low losses in comparison to other ceramic types such as alumina/silicon carbide (ACSR).　　The low power consumption　　The low power consumption is another advantage of tantalum capacitors. Since they have a low voltage drop, they require less energy to run at full capacity. This means that you will use less electricity per day than you would with other types of capacitors. Another benefit is that your system will generate less heat during operation so there’s no need for fans or cooling systems.　　The high energy density　　The high energy density of tantalum capacitors is a great substitute for the traditional ceramic capacitors. This is because it has a high electrical conductivity, which makes it an excellent choice for use in applications that require high power densities or large currents.　　In addition to its excellent electrical properties, tantalum capacitors also have the ability to be stacked together to form larger assemblies for even greater power handling capacity. These stacking designs can be used as independent units or as building blocks toward larger projects.　　Resistance to high temperatures and voltages　　Tantalum capacitors have low temperature coefficients and can withstand high voltage applications without any problems, unlike the aluminum electrolytic type which has a low coefficient of thermal expansion at elevated temperatures.What is polarity on tantalum capacitor　　Tantalum capacitor has one-way conductivity, which is called “polarity”, when using, the current should be accessed according to the positive and negative direction of the power supply, the anode (positive) of the capacitor is connected to the “+” pole of the power supply, and the cathode (negative) is connected to the “-” pole of the power supply, if the capacitor is connected wrongly, not only the capacitor can not play a role, but also the leakage current is very large, and the core will be hot in a short time, and the oxide film will be destroyed and then fail.　　In general, positive polarity means positive terminal of the battery is connected to positive terminal of the capacitor while negative polarity means that it is connected to negative terminal of the capacitor.

Since IC voltage fluctuation and heat generation are major issues that must be tackled to achieve stable device operation, it is necessary to both increase the capacitance of the capacitors used to suppress voltage fluctuations and to mount large, high-performance heat sinks (cooling units) on the ICs. Murata has proposed component costs reduction through problem solving using conventional low-profile and high-capacitance products as well as by reducing the number of components used.　　However, there is a growing demand for lower ESR products as a response to noise amplification due to the application of larger currents. Murata has now developed this product with a ESR value improved by 25% while maintaining the height and high-capacitance of conventional products. With this product, Murata contributes to providing stable device power supply while suppressing mounting areas and costs of electronic components.　　Specifications
