Varistors Datasheet C-III Series Radial Leaded Varistors RoHS 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 & Benefits Leadfree, Halogen-Free A vailable in tape and reel for automatic insertion Also and RoHS compliant Additional Information available with crimped and/ High energy absorption or trimmed lead styles capability WTM 40J to 530J (2ms) No derating up to 85C ambient High pulse lif e rating T he C-III Seriesis supplied High peak pulse in 10mm, 14mm and current capability 20mm disc versions with Resources Accessories Samples I TM 3500A to various lead options 10,000A (8/20s) Wide operating voltage Agency Approvals range VM(AC)RMS 130V to 1000V Agency File Agency Agency Approval Number UL1449 E320116 CECC 42201-006 IEC 61051-1 IEC 61051-2 116895 IEC 60950-1 (Annex Q) for 14mm and 20mm only CECC 42201-006 IEC 61051-1 IEC 61051-2 E1273/F IEC 60950-1 (Annex Q) for 14mm and 20mm only 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 ) 130 to 1000 V M(AC)RMS Transients Single-Pulse Peak Current (I ) 8/20s Wave TM 3500 to 10,000 A (See Peak Pulse Current Test Waveform) Single-Pulse Energy Range (W ) 2ms Rectangular Wave 40 to 530 J TM Operating Ambient Temperature Range (T ) -55 to +85 C A Storage Temperature Range (T ) -55 to +125 C STG V Temperature Coefficient (a ) of Clamping Voltage (V ) at Specified Test Current <0.01 %/C C Hi-Pot Encapsulation (COATING Isolation Voltage Capability) 2500 V COATING Insulation Resistance 1000 M Caution: Stresses above those listed inAbsolute Maximum Rating may cause permanent damage to the device.
