Murata PRG21BC1R0MM1RK Overcurrent Protection Thermistor

The PRG21BC1R0MM1RK is a compact surface-mount PTC thermistor designed for overcurrent protection and circuit safety in electronic devices. It features rapid response to overcurrent conditions, automatically resets after fault removal, and is suitable for miniaturized circuits due to its small size of 2.0x1.25mm. With a maximum voltage of 16V, hold current of 138mA at +85°C, trip current of 740mA at +25°C, and resistance of 19Ω at 25°C, this thermistor offers reliable performance for circuit protection. Its stable ceramic resistance, lightweight, and absence of leads make it ideal for modern electronic applications.
