How to distinguish the role of color ring inductor in circuit from color ring resistance
Color code inductance is also called color ring inductance. When the color ring inductor uses the current through the circuit, only fixed magnetic force lines are displayed around the inductor.
In order to improve your understanding of color ring inductor, the following is related content of color ring inductor sorted out by AMEYA360 electronic components purchasing network, hoping to provide you with reference and help. However, when the color ring inductor passes an alternating current through the coil, the magnetic force line around the color ring inductor changes with time.
First, the role of color ring inductance in the circuit
1, screen signals, color code inductance can play a role of frequency selection, when the color code inductance and electrolytic capacitor in parallel can be composed of tuning circuit. The inductance and capacitive reactance of the color code inductor in the circuit are opposite, so that the natural oscillation frequency f0 in the circuit is equal to the frequency f of the non-AC signal, so as to play a role of signal screening.
2, inhibit electromagnetic wave interference, that is, inhibit EMC interference. Color code inductor and capacitor are combined to form LC filter circuit, in which EMC interference can be suppressed.
3, stable current, color ring inductance plays a role in the circuit to stabilize the current. When the current increases, the color ring inductor generates induced electromotive force to prevent the current from increasing. When the current decreases, the color ring inductor will release the energy previously stored, thus reducing the current reduction.
