PTC Type Thermistor For Overcurrent Protection Short Response Time For Rapid Protection

PTC is the abbreviation of Positive Temperature Coefficient, which means a positive temperature coefficient, and generally refers to semiconductor materials or components with a large positive temperature coefficient. Usually the PTC we refer to refers to the positive temperature coefficient thermistor, referred to as the PTC thermistor. PTC thermistor is a typical temperature-sensitive semiconductor resistor. When it exceeds a certain temperature (Curie temperature), its resistance value increases stepwise with the increase of temperature.



Application

◆ Over current protection in:
-Industrial electronics
-Consumer electronics
-Electronic data processing
◆ Short current protection

Features

◆ Short response time for rapid protection
