Description
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 ve 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.
Features
• Breakthrough in low voltage varistor design provides high peak surge current rating
• Reduced footprint and volume required for surge protection
• Optional phenolic coating
• High peak surge current rating up to 8KA (8/20 μs pulse)
• Wide operating voltage
