C-III Varistor Series
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
lineTransient Voltage Surge Suppressor (TVSS)
product environment and other similar applications
requiring high transient energy and peak current
capability in a relatively small package size.
