2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 09/14/17 Metal-Oxide Varistors (MOVs) Surface Mount Varistors > CH Series 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. Features RoHS compliant Leadless, surface mount chip in 5 x 8mm Size Voltage ratings V M(AC)RMS 14V to 275V Supplied in tape and reel or bulk pack No derating up to 125C ambient High surge rated up to 600A Agency Approvals Absolute Maximum Ratings For ratings of individual members of a series, see Device Ratings and Specifications chart Continuous CH Series Units Steady State Applied Voltage: AC Voltage Range (V M(AC)RMS ) 14 to 275 V DC Voltage Range (V M(DC) ) 18 to 369 V Transient: Peak Pulse Current (I TM ) For 8/20 s Current (See Figure 2) 100 to 600 A Single Pulse Energy Range For 10/1000 s Current Wave (W TM ) 1.0 to 8.0 J Operating Ambient Temperature Range (T A ) -55 to +125 C Storage Temperature Range (T STG ) -55 to +150 C Temperature Coefficient ( V) of Clamping Voltage (V C ) at Specified Test Current <0.01 %/C CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
