Series: UltraMOV25S
UltraMOVTM 25S Varistor Series - High Peak Surge Current Radial Lead Varistor
Technology: Varistors
The UltraMOVTM 25S Varistor Series is designed for applications requiring high peak surge current ratings and high energy absorption capability. UltraMOVTM varistors are primarily intended for use in AC Line Voltage applications or other products that require voltage clamping of high transient surge currents from sources.

These devices have 25mm square forms are produced in a radial lead package and offered with straight leads. UltraMOVs are manufactured with recognized epoxy encapsulation and are rated for ambient temperatures up to 85℃ with no derating. This 25S Series is LASER-branded and is supplied in bulk packaging.

Features
