AUMOV™ Series AEC-Q200 Compliant Radial Varistors

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