PRG Series PTC Thermistors

Murata Electronics PRG Series PTC Thermistors are posistors for overcurrent protection that offer a voltage rating up to 32V and a current range of 10mA to 75mA. These thermistors feature a compact design, low profile, and a wide operating temperature range of -20°C to +85°C. PRG thermistors automatically return to their initial state when the overcurrent is eliminated and can be used repeatedly. Murata Electronics PRG Series PTC Thermistors are suitable for various types of equipment, including aircraft, aerospace, disaster, medical, crime prevention, and transportation.
