MT ThermoFuse™ Varistors

TDK MT ThermoFuse™ Varistors are equipped with monitor outputs and integrated thermal protective components for overvoltage protection. These specially developed quadratic disk varistors are connected in series with a patented thermal protective component design. In the case of a persistent overvoltage and heating of the TDK varistor, the fuse is activated and separates the varistor from the circuit with a high level of reliability. This prevents potential damage to the PCB or the components installed in the varistor’s vicinity.
