Surface Mount Varistors

Transient Voltage Surge Suppressor

RoHS

CH Varistor Series

CH series transient surge suppressors are small, metal-oxide varistors

(MOVs) manufactured in leadless chip form. They are intended for use in a

variety of applications from low voltage DC to off-line board-level protection.

These devices, which have significantly lower profiles than traditional

radial-lead varistors, permit designers to reduce the size and weight and

increase the reliability of their equipment designs.

CH series varistors are available in a voltage range from 14V to

275V V

, and energy ratings up to 23J.

M(AC)RMS

See the Littelfuse Multilayer Suppressor Series also.

CH Varistor Series

Power Dissipation Ratings

100

Continuous power dissipation capability is not an applicable design

requirement for a suppressor, unless transients occur in rapid succession.

Under this condition, the average power dissipation required is simply 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.

Furthermore, the operating values need to be derated at high tempera-

tures as shown in Figure 1. Because varistors can only dissipate a

relatively small amount of average power they are, therefore, not suitable

for repetitive applications that involve substantial amounts of average

power dissipation.
