The C-III Series of metal oxide varistors are specifically designed for high surge energy absorption ratings. 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.
The C-III series is supplied in 14 and 20mm disc versions with various lead options.
These types are shipped in bulk or Tape and Reel packaging.
Part number and brand information is provided in the Ratings Table.
