Varistor Products

High Energy, High Multiple Pulse Capability Radial Lead

The C-III Series of metal-oxide varistors are specifically designed for

applications requiring high surge energy absorption ratings and superior

multiple pulse absorbtion 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 appli-

cations requiring high transient energy and peak current capability in a

relatively small package size.

The C-III series is supplied in 10mm, 14mm 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.
