2017 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 09/14/17 Metal-Oxide Varistors (MOVs) Radial Lead Varistors > UltraMOV Varistor Series Description The UltraMOV Metal Oxide Varistor Series is designed for applications requiring high peak surge current ratings and high energy absorption capability. UltraMOV varistors are primarily intended for use in AC Line Voltage applications such as Surge Protection Device (SPD), Uninterruptable Power Supplies (UPS), AC Power Taps, AC Power Meters, or other products that require voltage clamping of high transient surge currents from sources such as lightning, inductive load switching, or capacitor bank switching. These devices are produced in radial lead package sizes of 7,10,14 and 20mm and offered in a variety of lead forms. UltraMOV varistor are manufactured with recognized epoxy encapsulation and are rated for ambient temperatures up to 85C with no derating. This Series is LASER-branded and is supplied in bulk, ammo pack (fan- fold), or tape and reel packaging. Features Lead-free, Halogen-Free and RoHS compliant High peak surge current rating (I TM ) up to 10kA, single 8 x 20 pulse, (20mm) Standard operating voltage range compatible with common AC line voltages (130 V AC to 625 V AC ) Characterized for maximum standby current (Leakage) Custom voltage types available Standard lead form and lead space options High operating temperature range up to 125C (phenolic coating option). 10mm, 14mm and 20mm devices are UL Recognized and TUV certified with 800V isolation voltage rating 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 UL1449 E320116 3 CECC 42201-006 IEC 61051-1 IEC 61051-2 IEC 60950-1 (Annex Q) for 14mm and 20mm only 116895 1 CSA C22.2 No. 1 91788 CECC 42201-006 IEC 61051-1 IEC 61051-2 IEC 60950-1 (Annex Q) for 10mm, 14mm and 20mm only IECQ-C BSI 14.0001 1 IEC/EN 61051-1 IEC 61051-2 IEC 61051-2-2 IEC 60950-1 (Annex Q) for 10mm, 14mm and 20mm only J 50324242 2 Continuous UltraMOV Varistor Series Units Steady State Applied Voltage: AC Voltage Range (V M(AC)RMS ) 130 to 625 V Transients: Single-Pulse Peak Current (I TM ) 8x20 s Wave (See Figure 2) 1,750 to 10,000 A Single-Pulse Energy Range (W TM ) 2ms Square Wave 12.5 to 400 J Operating Ambient Temperature Range (T A ) for Epoxy coated -55 to +85 C Operating Ambient Temperature Range (T A ) for Phenolic coated -55 to +125 C Storage Temperature Range (T STG ) for Epoxy coated -55 to +125 C Storage Temperature Range (T STG ) for Phenolic coated -55 to +150 C Temperature Coefficient (a V ) of Clamping Voltage (V C ) at Specified Test Current <0.01 %/C Hi-Pot Encapsulation (COATING Isolation Voltage Capability) 2500 V COATING Insulation Resistance 1000 M 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. UltraMOV Varistor Series RoHS Notes: . Epoxy coated only. 2. Phenolic coated only. 3. All epoxy coated sizes are UL Recognized while only 10mm, 14mm, and 20mm phenolic coated parts are UL recognized.
