Varistor Products Radial Lead Varistors > C-III series RoHS 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 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.

While the occurences of mWFL"USBOTJFOUTJTUIFSFRVJSFEDBQBCJMJUZ UIFSBUFE repetitive surge current for the C-III Series is 20 pulses for the 20mm units and 10 pulses for the 14mm Series. Typical Repetitive Surge Current Capability of C-III Series MOVs CLAMPING VOLTAGE AT 750A The transient surge rating serves as an excellent figure of merit for the C-III varistor. This inherent surge handling capability is one of the C-III varistor's best features. The enhanced surge absorption capability results from improved process uniformity and enhanced construction. The homogeneity of the raw material powder and improved control over the sintering and assembly processes are contributing factors to this improvement.
