Working principle of varistor

Varistors are made using ceramic technology, and their internal microstructure contains zinc oxide grains and grain boundaries. Due to the very neat arrangement of crystal molecules inside the grains, the electrical resistivity

The impact of capacitance on ESD

If only considering the ESD characteristics of capacitors, it is necessary to ensure that the voltage across the capacitor does not exceed its breakdown voltage. However, in some specific circuit designs, composed of capacitors and resistors
