Murata PRG18BC1R0MM1RB Ceramic PTC Thermistor

The PRG18BC1ROMM1RB is a ceramic PTC thermistor designed for overcurrent protection in electronic circuits. Its small SMD form factor (4.6x0.8mm or 0.6x0.3 inch) makes it ideal for miniaturized applications, providing rapid circuit protection against short circuits and overcurrent faults. The device automatically resets after abnormal conditions are removed, ensuring repeated use. It features a resistance of 19 ohms at 25°C with a tolerance of +20%, and withstands temperatures from -20°C to 85°C. Its stable resistance and fast response contribute to enhanced circuit safety and durability.
