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

Moreover, their durable construction guarantees enduring performance and reliability.　　Wide Temperature Range: These devices are engineered to operate flawlessly in the harshest temperature conditions, withstanding extreme lows of -40°C and scorching highs of 70°C and beyond. This unparalleled durability makes them incredibly versatile for a wide range of environments and applications.　　High Efficiency: Supercapacitors have high charge/discharge efficiency, typically exceeding 95%, resulting in minimal energy loss during energy transfer.　　Reduced Environmental Impact: Supercapacitors are widely regarded as a greener alternative to conventional batteries. Unlike their counterparts, they do not contain any hazardous substances such as heavy metals, making them not only safer but also more environmentally friendly. Their recyclability is greatly simplified, further contributing to their positive impact on sustainability.　　What Are the Downsides of Supercapacitors?　　Low Energy Density: Supercapacitors store significantly less energy per unit volume or weight compared to conventional batteries. This limits their suitability for applications requiring long-term energy storage.　　Voltage Limit: Supercapacitors typically operate at low voltages, requiring complex arrangements in some applications to reach higher voltage levels. This can make them less straightforward to integrate into certain systems.　　High Self-Discharge Rate: Supercapacitors tend to lose their stored energy more rapidly than batteries. Their high self-discharge rate means they may not be the best choice for applications requiring long-term energy retention without frequent recharging.　　Cost: Supercapacitors are generally more expensive than traditional batteries. While their long cycle life can offset this cost in some cases, the initial investment can be a barrier in certain applications.

Murata ：Automotive-Grade Ceramic Capacitors are Just 0.18mm Thick

　　Murata has extended their lead in the manufacture of multi-layer ceramic capacitors for automotive applications with the release of their LLC series. The components feature a reversed termination for low ESL and are in a world’s-first 0.18mm profile package. Footprint is just 0.5 x 1.0mm for 1µF capacitance making the parts the smallest in the market.　　The LLC series uses Murata’s proprietary thin-layer forming and high-precision lamination technology, along with advanced material atomization and homogenization techniques to achieve about 20% reduction in component height compared with existing parts. This opens up the potential to more-easily fit the capacitors on the back-side of circuit boards, even amongst solder ball terminations, locating the parts in optimum positions for decoupling of processor power rails, close to the die. This in turn allows fewer capacitors to be used, saving cost, and increasing system reliability.　　Along with their low ESR, the reduction in ESL achieved reduces the high-frequency impedance of the capacitors. This improves circuit performance to meet the requirements of modern, low-voltage, compute-intensive applications such as automotive advanced driver-assistance systems (ADAS).　　The automotive-grade LLC series complies with AEC-Q200 requirements, passing the 1000 temperature cycle test and temperature/humidity endurance test of 85°C at 80-85% humidity for 1000 hours.

What is a mica capacitor? Why are mica capacitors used?

　　What is a mica capacitor?A mica capacitor represents a capacitor variant employing mica as its dielectric medium. Capacitors, in essence, emerge as passive constituents of electronics, devised to stockpile and disburse electrical energy by fostering an electric field amid two conductive plates, segregated through a non-conductive entity designated as a dielectric. Mica capacitors, in particular, leverage mica—a naturally occurring mineral—as their choice of dielectric material.　　Why are mica capacitors used?The preference for mica capacitors roots in several factors, predominantly stemming from their distinctive attributes:　　1.Sustained Stability: Mica capacitors lay claim to extraordinary, enduring stability, characterizing minimal fluctuations in capacitance magnitude over extensive time spans. This inherent trait renders them ideal for applications that hinge on precision and steadfastness.　　2.Exemplary Dielectric Quality: Mica, serving as the dielectric, showcases stellar electrical insulation properties coupled with robust dielectric potency. It successfully withstands substantial voltage levels without succumbing to breakdown.　　3.Negligible Losses: Mica capacitors exhibit a commendably low dissipation factor, resulting in meager losses, thereby ensuring trifling energy dissipation in the form of heat during operational phases. This attribute proves invaluable in scenarios necessitating heightened efficiency.　　4.Suited to High Frequencies: These capacitors find their niche in high-frequency deployments, particularly in RF circuits. Their low losses and unwavering capacitance values become indispensable in such contexts.　　Where are mica capacitors used?Mica capacitors extend their presence across an expansive spectrum of electronic apparatus and circuits, encompassing:　　1.RF Circuits: Mica capacitors claim eminence in the realm of radio frequency circuits, as their enduring characteristics ensure the unswerving preservation of precise capacitance levels, even amidst fluctuating temperatures.　　2.Audio Equipment: High-end audio equipment benefits from the deployment of mica capacitors, where their low distortion and minimal losses conspire to elevate sound quality to superior echelons.　　3.Aerospace and Military Electronics: The discerning requirements of aerospace and military applications make mica capacitors the preferred choice. Their unwavering performance under demanding conditions becomes a pivotal asset.　　4.Medical Instruments: Precision medical instruments draw upon mica capacitors to assure unerring measurements and a reliable operational milieu.　　5.Telecommunication Systems: In telecommunications equipment, these capacitors emerge as stalwart allies in preserving signal fidelity while mitigating signal attenuation.　　What is mica capacitor made of?A quintessential mica capacitor embodies several core components:　　1.Mica Dielectric: The heart of the capacitor lies within the mica dielectric—a wafer-thin sheet of mica material. Mica assumes this role by virtue of its stability and insulating prowess.　　2.Metallic Foil Electrodes: Positioned on either side of the mica dielectric are two metallic foil electrodes. Typically fashioned from silver, these electrodes bestow the capacitor with the moniker “silver mica capacitor.”　　3.Lead Wires: Lead wires become affixed to the metallic foil electrodes, facilitating electrical connections to the capacitor.　　4.Protective Encasement: Safeguarding the capacitor from environmental rigors and physical harm, an insulating material—such as epoxy or ceramic—often envelops it.　　What is the difference between mica and ceramic capacitors?Mica capacitors and ceramic capacitors, while both capacitors, diverge considerably in their attributes:　　1.Diverse Dielectric Media: The most salient distinction arises from their disparate dielectric materials. Mica capacitors bank on mica as the dielectric, while ceramic capacitors harness ceramic materials like barium titanate or ceramic compounds.　　2.Stability Spectrum: Mica capacitors are celebrated for their prolonged stability, characterized by minimal capacitance fluctuations over time. Conversely, ceramic capacitors are more susceptible to variations in capacitance triggered by temperature and voltage perturbations.　　3.Frequency Domain: Mica capacitors are aptly suited for high-frequency applications, given their minimal losses, whereas ceramic capacitors, while versatile, may exhibit subpar performance in high-frequency settings.　　4.Size Considerations: Mica capacitors tend to occupy more physical space than their ceramic counterparts bearing equivalent capacitance values, rendering them less than ideal for diminutive electronic configurations.　　5.Economical Aspects: In economic terms, mica capacitors generally command higher prices compared to ceramic capacitors, with the latter proving more cost-effective for a multitude of applications.　　What material is used in mica capacitor?　　The fundamental building blocks of mica capacitors encompass mica as the dielectric and silver for the electrodes. Mica, as a naturally occurring mineral, is recognized for its electrical insulation capabilities, while silver earns its place owing to its outstanding conductivity and steadfastness.　　What is the polarity of a silver mica capacitor?　　Notably, mica capacitors, inclusive of silver mica capacitors, navigate free of the constraints of polarity. This signifies that their connection to an electrical circuit need not be governed by polarity considerations. Unlike certain capacitors—like electrolytic capacitors—that bear distinct positive and negative terminals, mica capacitors permit connection in any orientation without prejudice.
