TMOV25SP385M

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 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 component recognition requirements of UL1449 3rd edition for both cord connected and permanently connected SPD end products.
