T Series ThermoFuse™ Varistors

TDK T Series ThermoFuse™ Varistors are designed for a maximum operating voltage of 130VRMS to 1000VRMS. These 14mm and 20mm varistors withstand surge currents of up to 10A (8/20μs) and absorb up to 410J (2ms). The housed devices consist of a disk varistor in series with a thermally coupled fuse. If the varistor overheats, the thermal fuse activates and disconnects it from the power circuit. This overheating protection helps prevent fires, increases reliability, and protects the equipment. The housing and coating of the varistor are made of flame-retardant material. TDK T Series ThermoFuse Varistors feature three terminals. Two are connected to the active lines while the third terminal can be used for status signaling. Applications include household appliances, power supply units, inverters in solar power systems, lighting, communication and data systems, transient voltage surge suppressors (TVSS), and electronic metering.
