Metal-Oxide Varistors (MOVs) Radial Lead Varistors > TMOV and iTMOV Varistor Series RoHS TMOV and iTMOV 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 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 iTMOV varistors integrated thermal element, in conjunction with appropriate enclosure design, helps facilitate 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 proximity of the integrated thermal element to the MOV body. The integrated Agency Approvals configuration also offers lower inductance than most discrete solutions resulting in improved clamping Agency Agency Approval Agency File Number performance to fast overvoltage transients. UL1449 E320116 The iTMOV varistor differs from the TMOV varistor by the inclusion of a third lead for the purpose of indicating that QC 42201-C001, the MOV has been disconnected from the circuit. This lead QC 42201-A001, IECQ-C BSI 15.0009 facilitates connection to monitoring circuitry. IEC 60950-1 (Annex Q) IEC 61051-1, Additionally TMOV and iTMOV varistors are wave IEC 61051-2, 40021525 solderable, thus simplifying end product assembly by IEC 60950-1 (Annex Q) reducing the the expense and rework associated with hand soldering operations.
