Series: C-III

High Energy Radial Leaded Varistor
Product Status| Activei
info
The C-III Series of metal oxide varistors are specifically designed for high surge energy absorption ratings. This is achieved through a special dielectric material formulation which also results in higher repetitive surge ratings than other MOV types.

The C-III series is primarily intended for use in AC line Transient Voltage Surge Suppressor (TVSS) product environment and other similar applications requiring high transient energy and peak current capability in a relatively small package size.
  • The C-III series is supplied in 14 and 20mm disc versions with various lead options.
  • These types are shipped in bulk or Tape and Reel packaging.
  • Part number and brand information is provided in the Ratings Table.

  • Lead–free, halogen-free, and RoHS compliant
  • High energy absorption capability WTM 40 J to 530 J (2 ms)
  • High pulse life rating
  • High peak pulse current capability ITM from 3.5 kA to 10 kA (8/20μs)ITM from 3.5 kA to 10 kA (8/20μs)
  • Wide range of operating voltages VM(AC)RMS 130V to 680V
  • Available in tape and reel for automatic insertion; Also available with crimped and/or trimmed lead styles
  • No derating up to 85ºC ambient
  • The C-III Series is supplied in 10mm, 14mm and 20mm disc versions with various lead options
