Surface Mount Varistors
Transient Voltage Surge Suppressor
RoHS Pb 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 VM(AC)RMS , and energy ratings up to 23J.
See the Littelfuse Multilayer Suppressor Series also.
