UltraMOV 20mm Varistors

Littelfuse UltraMOV 20mm Varistors meet high peak surge current rating requirements with an operating voltage range compatible with common AC line voltages (130VAC to 625VAC). These metal oxide varistors are available in various lead forms and are rated for ambient temperatures up to +85°C with no derating. The lead-free, 20mm varistors can operate at temperatures up to +125°C and are characterized for maximum standby current (leakage). These features make the Littelfuse 20mm UltraMOV varistor series ideal for AC line voltage applications, LED lighting applications, and more.
