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.
