Varistor Products Radial Lead Varistors > TMOV and iTMOV Series RoHS TMOV and i TMOV Varistor Series Description The Littelfuse TMOV and iTMOV thermally protected varistors represent a new development in integrated circuit protection. Both versions are comprised of radial leaded MOVs (Met al Oxide Varistors) with an integrated thermally activated element designed to open in the event of overheating due to the abnormal over volt age, limited current, conditions outlined in UL1449. The TMOV and iTMOV varistor s integrated thermal element, in conjunction with appropriate enclosure design, helps facilit ate SPD module compliance to UL1449 for both cord connected and permanently connected applications. The TMOV and iTMOV varistors offer quick thermal response due to the close proximit y of the integrated thermal element to the MOV body. The integrated Agency Approvals configuration also offers lower induct ance than most discrete solutions resulting in improved clamping Agency Approval Agency File Number performance to fast over volt age transients. UL1414 E56529 The iTMOV varistor differs from the TMOV varistor by the inclusion of a third lead for the purpose of indicating that UL1449 E320116 the MOV has been disconnected from the circuit. This lead QC 42201-C0 01, facilit ates connection to monitoring circuitr y. QC42201-A0 01, E1274/F IEC 60950-1 (Annex Q) Additionally TMOV and iTMOV varistors are wave solderable, thus simplifying end product assembly by IEC 61051-1, reducing the the expense and rework associated with hand IEC 61051-2, 40 021525 soldering operations.
