Introduction

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 WTM 40J to 530J (2ms)
• High pulse life rating
• High peak pulse current capability ITM 3500A to 10,000A (8/20µs)
• Wide operating voltage range VM(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 85℃ ambient
• The C-III Series is supplied in 10mm, 14mm and 20mm disc versions with various lead options
• Phenolic Coated CIII Series devices are available with improved maximum operating maximum temperature 125℃
• These devices also have improved temperature cycling performance capability

Applications

• AC line Surge Protection Device (SPD) product
• Other similar applications requiring high transient energy and peak current capability in a relatively small package size
