LV UltraMOV varistors from Littelfuse offer higher surge current ratings in smaller disc sizes

USA: Littelfuse Inc., the global leader in circuit protection, has introduced the LV UltraMOV series of low voltage, high surge current, radial leaded varistors. They provide an ideal circuit protection solution for lower DC voltage applications by offering higher surge ratings than ever before available in such small disc sizes.

Their high peak surge current rating provides superior protection against high peak surges, including indirect lightning strike interference, system switching transients and abnormal fast transients from the power source.

Typical applications of these devices include LED lighting drivers, cordless phones, wireless base stations, audio devices, mobile phone chargers, security systems, fire alarm systems and automation control systems (PLCs).

“The LV UltraMOV Series is unrivaled in the industry in terms of its surge current rating, energy handling capabilities, and ability to withstand multiple strikes; no competitive product comes close,” said Johnny Chang, product manager, LV UltraMOV Series Varistor product line. “For example, a 10mm LV UltraMOV Series Varistor offers a maximum surge current rating that’s four times higher than a standard MOV of the same size.”
