LV UltraMOV Varistor Series
Description
Epoxy Coated
The Littelfuse LV UltraMOV® Varistor Series provides an ideal
circuit protection solution for DC voltage applications.
Phenolic Coated
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.
