C-III Varistor Series

RoHS

Description

The C-III 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 Series is primarily intended for use in AC

line Transient Voltage Surge Suppressor (TVSS)

product environment and other similar applications

requiring high transient energy and peak current

capability in a relatively small package size.
