TMOV14R140M

Varistor Products Thermally Protected TMOV® and iTMOV® Varistor Series The Littelfuse TMOV and iTMOV thermally protected varistors represent a new development in integrated circuit protection (patent pending). Both versions are comprised of radial leaded MOVs (Metal Oxide Varistors) with an integrated thermally activated element designed to open in the event of overheating due to the abnormal over-voltage, limited current, conditions outlined in UL1449. The iTMOV varistor differs from the TMOV varistor by the inclusion of a third lead for the purpose of indicating that the MOV has been disconnected from the circuit. This lead facilitates connection to monitoring circuitry. The TMOV and iTMOV varistors offer quick thermal response due to the close proximity of the integrated thermal element to the MOV body. The integrated configuration also offers lower inductance than most discrete solutions resulting in improved clamping performance to fast over-voltage transients. Additionally, TMOV and iTMOV varistors are wave solderable, thus simplifying end product assembly by reducing the expense and rework associated with hand soldering operations. The TMOV and iTMOV varistors are both recognized surge suppression components to UL 1449. The TMOV and iTMOV varistor’s integrated thermal element, in conjunction with appropriate enclosure design, helps facilitate TVSS module compliance to UL1449 for both cord connected and permanently connected applications. TMOV and iTMOV varistors are compatible for use with industry standard wave-soldering processes or recommended hand-soldering methods. ® ® 2 VARISTOR PRODUCTS Applications • TVSS Products • AC Panel Protection Modules • AC Line Power Supplies • Surge Protected Strip Connectors • AC Power Meters • Relocatable AC Power Taps • GFCI (Ground Fault Current Interupter) • UPS (Uninterruptable Power Supply) • White Goods • Plug-in TVSS • Inverters • AC/DC Power Supplies Features • Patent Pending Integrated Thermal Protection Device • Designed to facilitate compliance to UL1449 for TVSS product • High peak surge current rating up to 10kA • Wave solderable • Standard lead form and spacing option • Low Leakage • -55°C to +85°C Operating Temperature Range • Three-lead version available for indication purposes.
