Metal-Oxide Varistors (MOVs) Radial Lead Varistors > C-III Varistor Series C-III Varistor Series RoHS Description The C-III Varistor Series of Metal-Oxide Varistors (MOVs) are specifically designed for applications requiring high surge energy absorption ratings and superior multiple pulse absorption rating. This is achieved through a special dielectric material formulation which also results in higher repetitive surge ratings than other MOV types. The C-III Varistor Series is primarily intended for use in AC line Surge Protection Device (SPD) product and other similar applications requiring high transient energy and peak current capability in a relatively small package size.
