Chip Varistor
Varistors, variable resistors, are voltage - dependent resistors with bi-directional and symmetrical V/I characteristics. Metal Oxide Varistors, MOV, are primarily made of Zinc Oxide and some suitable additives. When varistors are exposed to over-voltage transient or surge, the varistors switch from stand-by state(nearly open circuits) to clamping state (highly conductive state). The major function is to protect equipments from being damaged by over-voltage transient. At leakage region, the V-I curve shows a linear relationship. The varistor is in high resistance mode and shows as an open circuit. At high current, the varistor is in low resistance mode and shows as a short circuit.
