Metal oxide varistor

Varistor

Definition

Zinc oxide varistors (zno or zov)

VDR (Voltage dependent resistor)

Leaded varistors

MOV (Metal Oxide varistor)

Metal oxide varistor (MOV or VDR) are voltage dependent resistors with symmetrical voltage-current characteristics which are designed to protect all kinds of electronic devices or elements from switching pulse or induced lightening surges. Its non linear characteristic with broad application range, mass production feasibility are gardually being used in various level of electric and electronic device from low to high voltages level protection (AC 11V to AC 1000V as available ranges).

The normal type of metal oxide varistor are radial lead varistors (MOV or VDR) that are designed to be used continuously across AC line primary or DC circuit for transient voltage and surge suppression.
