Description
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 8J.
See the Littelfuse Multilayer Suppressor Series also.
