High Energy Radial Lead
C-III Varistor Series
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 appli-
cations 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.

C-III Series Specifications
Power Dissipation Ratings
Should transients occur in rapid succession, the average power
dissipation is the energy (watt-seconds) per pulse times the number of
pulses per second. The power so developed must be within the
specifications shown on the Device Ratings and Specifications table for
the specific device.The operating values of a MOV need to be derated
at high temperatures as shown in Figure 1. Because varistors only
dissipate a relatively small amount of average power they are not
suitable 0for repetitive applications that involve substantial amounts of
average power dissipation.
