Using Murata's semi-conductive ceramics and electrode printing technologies, we offer PTC Thermistors and NTC Thermistors that are indispensable for over current protection and temperature sensing applications in electronic equipment.

PRG Series: SMD series PTC thermistor for overcurrent protection with resettable function suitable for use as a current limiting resistor.

PRF Series: SMD series chip PTC Thermistor is for overheat sensing for power transistors, power diodes and power ICs in hybrid circuits.

NCP Series: SMD series NTC Thermistor is for temperature sensing and temperature compensation circuits.
