General part information

SMOV25S421MP Series

Thermally protected SMOV25S Varistor Series for overvoltage circuit protection The SMOV25S Varistor Series offer an integrated thermal disconnect designed to open in the event of overheating due to abnormal overvoltage as outlined in UL1449 (3rd edition). These devices possess a separate micro-switch that can be used to indicate when the MOV is disconnected from the circuit.
