CH Varistor Series

RoHS

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.
