The AUMOV® Series Varistor offers 50% greater surge withstanding capability than existing technologies on the market for low DC voltage applications. The maximum peak surge current is rated up to 5KA (8/20μs pulse) to protect sensitive automotive systems from voltage transients induced by load dump and other transient events. This AEC-Q200 (Table 10) compliant series is available in five disc sizes: 5mm, 7mm, 10mm, 14mm and 20mm. It features a wide operating voltage range from 14VAC to 42VAC and 16VDC to 50VDC.

 Features:

  • Meets the stringent quality standards of AEC-Q200 (Table 10)
  • UL recognized
  • Optional phenolic coating for operating temps up to 125°C
  • High peak surge current rating and energy absorption capability
  • Reduced footprint and volume required for voltage surge protection
  • High resistance to thermal cycles for phenolic coating
  • Lead free, halogen free and RoHS compliant

Benefits:

  • Meets automotive industry requirements
  • Suitable for  harsh automotive environments
  • Helps meet UL1449 requirements
  • Well suited for the passenger compartment and the stringent temperature requirements of under-the-hood electronics
  • Provides robust protection against overvoltages induced by load dump, jump start, and other transients

 

Applications:

  • Body electronics systems
  • Powertrain systems
  • Infotainment system
  • Automotive control module protection
  • Motor or inductive load transient suppression
