Metal-Oxide Varistors (MOVs) Radial Lead Varistors > TMOV® and iTMOV® Varistor Series TMOV and iTMOV Varistor Series ® ® RoHS 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® varistor’s integrated thermal element, in conjunction with appropriate enclosure design, helps facilitate SPD module compliance to UL1449 for both cord connected and permanently connected applications. Agency Approvals Agency Agency Approval Agency File Number UL1449 E320116 QC 42201-C001, QC 42201-A001, IEC 60950-1 (Annex Q) IECQ-C BSI 15.0009 IEC 61051-1, IEC 61051-2, IEC 60950-1 (Annex Q) 40021525 Additional Information 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 overvoltage transients. 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. Additionally TMOV® and iTMOV® varistors are wave solderable, thus simplifying end product assembly by reducing the the expense and rework associated with hand soldering operations.

Specifications are subject to change without notice. Revised: 04/13/16 NOTES: • Dimensions in mm • Reel capacity varies with voltage. • Leads are crimped and in-line. This excludes the monitor lead on iTMOV® varistor which are not crimped and not in-line. • To order tape and reel option please add suffix 'L2T7' to end of standard part number. • Tape and reel option is available for rated voltages up to 420V. Contact factory regarding availability of higher voltages. • Contact Littelfuse for additional details.
