Metal-Oxide Varistors (MOVs) Radial Lead Varistors > TMOV®25S Varistor Series TMOV®25S Varistor Series RoHS Description Metal Oxide Varistors (MOVs) are rated for specific AC line operating voltages, and exceeding these limits through the application of a sustained abnormal over-voltage condition could result in overheating and damage to the MOV. The Littelfuse TMOV®25S Varistor Series was designed to address this condition in a single integrated package. The TMOV®25S Varistor Series incorporates a patented integrated thermally responsive element within the body of the device which will open-circuit the varistor in case of overheating due to the abnormal over-voltage events. The TMOV®25S Varistor Series meets the surge suppressor Agency Approvals component recognition requirements of UL1449 3rd edition for both cord connected and permanently Agency Agency Approval Agency File Number connected SPD end products.

C) Secondly, wave-soldering: This is a strenuous process E (º200 R U requiring pre-heat stages to reduce the stresses on AT150 R devices. E P M E100 T It is critically important that all preheat stage and the PREHEAT solder bath temperatures are rigidly controlled. The 50 recommended solder for the TMOV® Varistor Series is a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37 (Sn/ 0 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 Pb). Littelfuse also recommends an RMA solder flux.
