Ptc components

Key Attributes.

PTC is short for Positive Temperature Coefficient, ptc element is also called PTC heat sensitive resistance ceramic. It is a kind of semiconductor function ceramic with positive temperature coefficient. PTC thermistors is a typical temperature sensitive semiconductor resistor. Before reaching switching temperature( Tc),the resistance goes down as the temperature rises. When the temperature is in the range from switching temperature to heat uncontrollable teperature, the resistance rises sharply as the temperature ascends. This is what we call “ PTC domino affect”. Using different temperature coefficients, we can make different PTC sensitive ceramics for different applications. Due to the PTC thermistor is the most energy saving and safe compent, it is widely used in many fields such as household electrical appliances, electric power facilities, and electronic products, etc.
