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.

Under these extreme abnormal overvoltage conditions, some units will exhibit substantial heating, arcing and venting prior to opening. Modules should be designed to contain this possibility. Application testing is strongly recommended. For applications exceeding 85°C ambient temperature, the peak surge current and energy ratings must be reduced as shown above. Figure 3.

Two soldering methods are possible. Firstly, hand soldering: It is recommended to heat-sink the leads of the device. Secondly, wave soldering: It is critically important that all preheat stage and the solder bath temperatures are rigidly controlled. Figure 8. Lead–free Profile Figure 7.
