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 of-
fering higher surge ratings than ever before available in such
small discs.
The maximum peak surge current rating can reach up to 8KA
(8/20 μs pulse) to protect against high peak surges, including
indirect lightning strike interference, system switching tran-
sients 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 40V, and VDC voltage range of 14V to 56V.
