The Littelfuse LV UltraMOV™ Varistor Series provides an

ideal circuit protection solution for DC voltage applications.

The maximum peak surge current rating can reach up to

10kA (8/20μs pulse) to protect against the damage from

high peak surge current induced by 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 voltage range from 14V

to 125V.
