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.
