TMOV14RP300E Product Details

TMOV14RP300E and iTMOV14RP300E Varistor Series The Littelfuse TMOV14RP300E and iTMOV14RP300E thermally protected varistors represent a new development in integrated circuit protection. 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 overvoltage, limited current, conditions outlined in UL 1449. The iTMOV14RP300E varistor differs from the TMOV14RP300E varistor by the inclusion of a third party lead for the purpose of indicating that the MOV has been disconnected from the circuit. This lead facilitates connection to monitoring circuitry.The TMOV14RP300E and iTOMV 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, TMOV14RP300E and iTMOV14RP300E varistors are wave solderable, thus simplifying end product assembly by reducing the expense and rework associated with hand soldering operations.The TMOV14RP300E and iTMOV14RP300E varisors are both recognized surge suppression components to UL 1449.The TMOV14RP300E and iTMOV14RP300E varistor’s integrated thermal element, in conjunction with appropriate enclosure design, helps facilitate TVSS module compliance to UL 1449 for both cord connected and permanently connected applications.TMOV14RP300E and iTMOV14RP300E varistors are compatible for use with industry standard wave-soldering processes or recommended hand-soldering methods.
