The B72540T600K62 is a ThermoFuse varistor manufactured by EPCOS (TDK). This component provides reliable overvoltage protection for electronic circuits, with the added safety feature of an integrated thermal fuse. The thermal fuse disconnects the varistor if it overheats due to excessive surge events or continuous overvoltage conditions, preventing potential fire hazards and increasing overall system safety. These varistors are commonly used in power supplies, consumer electronics, and industrial equipment.
