What is a metal oxide varistor? The Metal Oxide Varistor or MOV is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. The Metal Oxide Varistor is designed to ...

Menlo Park, Calif. – The ROV series of metal-oxide varistors from Raychem Circuit Protection is available in diameters of 5 to 20 mm and rated from 18 to 1,800 volts. High current-handling and energy ...

Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of overvoltage conditions. Essentially, these voltage-dependent, nonlinear devices have ...

An ideal protection device must limit the energy going to the load being defended, to a sufficient minimum level, such that the load is not damaged. The protection device must survive this energy ...
