Description
The Littelfuse AUMOV® Varistor Series of low voltage, high surge current, radial leaded varistors provides an ideal circuit protection for load dump, jump start voltage transient conditions specifically for automotive applications. The maximum peak surge current rating is rated up to 5kA (8/20 μs pulse) to protect sensitive infotainment systems from voltage transients. This AEC-Q200 (Table 10) qualified series is available in five disc sizes: 5mm, 7mm, 10mm, 14mm and 20mm; it features a wide VDC voltage range from 16V to 825V.
Features
• Breakthrough in low voltage varistor design provides high peak surge current rating
• Phenolic and Silicone coating meet the stringent quality requirements of AEC-Q200 (Table 10)
• Reduced footprint and volume required for surge protection
• Optional phenolic coating for higher operating temperature up to 125ºC
• High peak surge current rating up to 5kA (8/20 μs pulse)
• Wide operating voltage range: 14VAC to 625VAC and 16VDC to 825VDC
• Five disc sizes available: 5, 7, 10, 14, and 20mm
• High resistance to thermal cycles for phenolic coating
• High energy absorption particularly for automotive load dump and jump start
• Lead–free, Halogen-Free and RoHS compliant
• Silicone coating option: High operating temperature combined with high isolation voltage capability: 125°C and 2500V, respectively
