Varistor Products Radial Leaded Varistors > LV UltraMOVTM Series LV UltraMOVTM Varistor Series Epoxy Coated 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 offering 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 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 VAC voltage range of 11V to 40V, and VDC voltage range of 14V to 56V. Phenolic Coated Agency Approvals Features Agency File Number E320116 (only Epoxy Coated) • 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 range VM(AC)RMS 11V to 40V and V M(DC) 14V to 56V • High operating temperature range up to 125ºC • 5 model sizes available: 5, 7, 10, 14, and 20mm • Standard lead options • Lead–free, Halogen-Free and RoHS compliant Applications • • • • • • LED lighting drivers Cordless phones Wireless base stations Audio devices Mobile phone chargers Security systems • Fire alarm systems • Automation Control Systems (PLCs) • Industrial Control Contact Relay • Surge Protection Devices Absolute Maximum Ratings • For ratings of individual members of a series, see Device Ratings and Specifications chart Low Voltage Series Units AC Voltage Range (VM(AC)RMS) 11 to 40 V DC Voltage Range (VM(DC)) 14 to 56 V 500 to 8,000 A Continous: Steady State Applied Voltage: Transient: Non-Repetitive Surge Current, 8/20µs Waveform (ITM) Non-Repetitive Energy Capability, 2ms Waveform (WTM) 0.8 to 140 J -40 to +85 °C Operating Ambient Temperature Range (TA) for Phenolic coated -40 to +125 °C Storage Temperature Range (TSTG) for Epoxy coated -40 to +125 °C Storage Temperature Range (TSTG) for Phenolic coated -40 to +150 °C < 0.01% °C Hi-Pot Encapsulation (Isolation Voltage Capability) for Epoxy coated 2500 V Hi-Pot Encapsulation (Isolation Voltage Capability) for Phenolic coated 500 V >1,000 MΩ Operating Ambient Temperature Range (TA) for Epoxy coated Temperature Coefficient (αV) of Clamping Voltage (VC) at Specified Test Current Epoxy Coating Insulation Resistance CAUTION: Stresses above those listed in "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. © 2014 Littelfuse, Inc.
