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 (V
M(AC)RMS
), and energy ratings up to 8J.
See the Littelfuse Multilayer Suppressor Series also.
