Ptc heater principle

PTC heater is an electric heater based on semiconductor materials, and its working principle is to use the positive temperature coefficient characteristics of PTC materials for heating. PTC materials will generate a lot of heat after being electrified, which will heat up the surrounding environment. When the temperature rises to a certain extent, the resistance of PTC material increases sharply, which limits the flow of current and reaches a self-stable state. PTC electric heater has the advantages of fast response, uniform heating, safety and reliability, and is widely used in household appliances, automobiles, medical care, military industry and other fields, and also has a good application prospect in temperature control.
