TMOV20RP300M Datasheet | Littelfuse

ription The Littelfuse TMOV® and i TMOV® thermally protected varistors represent a new development in integrated circuit protection. Both versions are prised of radial leaded Metal Oxide Varistors (MOVs) with an integrated thermally activated element designed to open in the event of overheating due to the abnormal overvoltage, limited current, conditions outlined in UL1449. The TMOV® and i TMOV® varistor’s integrated thermal element, in conjunction with appropriate enclosure design, helps facilitate SPD module pliance to UL1449 for both cord connected and permanently connected applications. The TMOV® and i TMOV® 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 overvoltage transients. The i TMOV® 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. Additionally TMOV® and i TMOV® varistors are wave solderable, thus simplifying end product assembly by reducing the the expense and rework associated with hand soldering operations.
