2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 09/14/17 Metal-Oxide Varistors (MOVs) Radial Lead Varistors > C-III Varistor Series C-III Varistor Series Description The C-III Varistor Series of Metal-Oxide Varistors (MOVs) are specifically designed for applications requiring high surge energy absorption ratings and superior multiple pulse absorption rating. This is achieved through a special dielectric material formulation which also results in higher repetitive surge ratings than other MOV types. The C-III Varistor Series is primarily intended for use in AC line Surge Protection Device (SPD) product and other similar applications requiring high transient energy and peak current capability in a relatively small package size. Features Lead-free, Halogen- Free and RoHS compliant High energy absorption capability W TM 40J to 530J (2ms) High pulse life rating High peak pulse current capability I TM 3500A to 10,000A (8/20 s) Wide operating voltage range V M(AC)RMS 130V to 1000V Available in tape and reel for automatic insertion; Also available with crimped and/or trimmed lead styles No derating up to 85C ambient The C-III Series is supplied in 10mm, 14mm and 20mm disc versions with various lead options Agency Approvals Absolute Maximum Ratings For ratings of individual members of a series, see Device Ratings and Specifications chart Continuous C-III Series Units Steady State Applied Voltage: AC Voltage Range (V M(AC)RMS ) 130 to 1000 V Transients: Single-Pulse Peak Current (I TM ) 8/20 s Wave (S ee Peak Pulse Current Test Waveform) 3500 to 10,000 A Single-Pulse Energy Range (W TM ) 2ms Rectangular Wave 40 to 530 J Operating Ambient Temperature Range (T A ) -55 to +85 C Storage Temperature Range (T STG ) -55 to +125 C Temperature Coefficient (a V ) of Clamping Voltage (V C ) at Specified Test Current <0.01 %/C Hi-Pot Encapsulation (COATING Isolation Voltage Capability) 2500 V COATING Insulation Resistance 1000 M 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.
