Application of capacitance

Capacitor in the electronic field of filtering, signal filtering, bypass, signal coupling, resonance, compensation, energy storage, DC isolation and so on. In the power circuit, often use a large capacitor with small capacitor to do filtering, capacitance has the characteristics... Read more

Introduction to varistor devices

Varistor function: Lightning protection, overvoltage protection, when the varistor is not working, it has a high impedance (several megohm). When the transient surge voltage appears, the impedance of the varistor becomes low (several ohms), which makes the original circuit short... Read more
