UltraMOV™ 25S Varistor Series


A series of high-peak surge current radial lead varistors from Littelfuse


Littelfuse UltraMOV™ 25S Varistor series are designed for applications requiring high peak surge current ratings and high-energy absorption capability. UltraMOV varistors are primarily intended for use in AC line voltage applications or other products that require voltage clamping of high transient surge currents.

These devices have 25mm square forms and are produced in radial lead packages that are also offered with straight leads. UltraMOVs are manufactured with recognized epoxy encapsulation and are rated for ambient temperatures up to 85°C with no derating. The 25S series is LASER-branded and is supplied in bulk packaging.
