Revised: 09/14/17 Metal-Oxide Varistors (MOVs) Radial Leaded Varistors > HMOV Varistor Series Description Features Agency Approvals Absolute Maximum Ratings For ratings of individual members of a series, see Device Ratings and Specifications chart Agency Agency Approval Agency File Number UL 1449 E320116 1 IEC/EN 61051-1 IEC 61051-2 IEC 61051-2-2 IEC 60950-1 (Annex Q) 10mm,14mm and 20mm with phenolic coating only J 50324242 2 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. LV UltraMOV Varistor Series RoHS Breakthrough in low voltage varistor design provides high peak (up to 10KA) surge current rating Reduced footprint and volume required for surge protection Wide operating voltage range V M(AC)RMS 11V to 95V and V M(DC) 14V to 125V Lead-free, Halogen-Free and RoHS compliant High operating temperature range up to 125C (phenolic coating option) 5 model sizes available: 5, 7, 10, 14, and 20mm 10mm, 14mm and 20mm devices are UL Recognized and TUV certified with 800V isolation voltage rating. Applications LED lights Cordless phones Audio and video devices Mobile phone chargers Security systems Fire alarm systems Automation control systems Industrial control contact relays Surge protection device Telecom power systems Wireless base stations Phenolic Coated Epoxy Coated The Littelfuse LV UltraMOV Varistor Series provides an ideal circuit protection solution for DC voltage applications. The maximum peak surge current rating can reach up to 10kA (8/20 s 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. Low Voltage Series Units Continous: Steady State Applied Voltage: AC Voltage Range (V M(AC)RMS ) 11 to 95 V DC Voltage Range (V M(DC) ) 14 to 125 V Transient: Non-Repetitive Surge Current, 8/20s Waveform (I TM ) 500 to 10,000 A Non-Repetitive Energy Capability, 2ms Waveform (W TM ) 0.8 to 150 J Operating Ambient Temperature Range (T A ) for Epoxy coated -40 to +85C Operating Ambient Temperature Range (T A ) for Phenolic coated -40 to +125C Storage Temperature Range (T STG ) for Epoxy coated -40 to +125C Storage Temperature Range (T STG ) for Phenolic coated -40 to +150C Temperature Coefficient ( V) of Clamping Voltage (V C ) at Specified Test Current < 0.01%C Hi-Pot Encapsulation (Isolation Voltage Capability) for Epoxy coated 2500 V Hi-Pot Encapsulation (Isolation Voltage Capability) for Phenolic coated 800 V Epoxy Coating Insulation Resistance >1,000 M Notes: 1. All epoxy coated sizes are UL Recognized while only 10mm, 14mm, and 20mm phenolic coated parts are UL recognized. 2. Phenolic coated only. Additional Information Datasheet Samples Resources
