◆FEATURES

PTC heating is a kind of positive temperature coefficient of semiconductors functional ceramics. Once more than PTC thermistor materials transition temperature (Tc), the rise of resistance with temperature of PTC heating element is almost a higher step type, this is called the PTC effect. According to the voltage and current characteristics of PTC, use PTC effect, according to the different transformation temperature, different temperature coefficient, can produce the different USES of PTC heating piece. PTC heating has high reliability, consistency, good stability, easy to use, safe, long life and other advantages, widely used in household appliances, electronic equipment, etc.
