The Littelfuse LV UltraMOV™ Series of low voltage, high surge current, radial leaded varistors provides an ideal circuit protection solution for lower DC voltage applications by offering higher surge ratings than ever before available in such small discs.

The maximum peak surge current rating can reach up to 10kA (8/20 μs pulse) to protect against high peak surges, including indirect lightning strike interference, system switching transients and abnormal fast transients from the power source.

Available in five model sizes: 5mm, 7mm, 10mm, 14mm and 20mm, these device feature a wide VAC voltage range of 11V to 95V, and VDC voltage range of 14V to 125V.
