C-III Radial Leaded Metal-Oxide Varistors

Littelfuse C-III Radial Leaded Metal-Oxide Varistors (MOVs) are designed for applications requiring high surge energy and superior multiple pulse absorption ratings. The C-III varistors are supplied in 10mm, 14mm, and 20mm disc versions with various lead options. A unique dielectric material formulation produces more repetitive surge ratings than other MOV types. The C-III varistors are primarily intended for use in AC line Surge Protection Device (SPD) products and similar applications requiring high transient energy and peak current capability in a relatively small package size.
