Metal-Oxide Varistors Datasheet TMOV 25S Varistor Series Radial Lead Varistors 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 TMOV25S Varistor Series was designed to address this condition in a single integrated package. The TMOV25S 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 TMOV25S Varistor Series meets the surge suppressor component recognition requirements of UL1449 3rd edition for both cord connected and permanently connected SPD end products.
