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.
