Murata PRG18BB471MB1RB Overcurrent Protection Thermistor

The PRG18BB471MB1RB is a compact SMD PTC thermistor designed for overcurrent protection and self-resetting circuit protection in electronic devices. It automatically interrupts current flow during overcurrent conditions, such as short circuits, and then resets once conditions normalize. This thermistor features a maximum voltage of 2V, hold current of 5mA (at +75°C), trip current of 21mA (at +25°C), and maximum current of 60mA. Built with ceramic PTC material, it offers stable resistance, small size, light weight, and no lead terminations—ideal for miniaturized electronic circuits with reliable overcurrent protection.
