The PTC ceramic heaters include a ceramic material that is designed for a particular temperature depending on the particular application. An electrical current is applied to the ceramic heater that generates heat as long as the temperature of the ceramic heater is below the designed temperature. If the ceramic heater reaches the designed temperature, then the resistance of the ceramic material goes up, and the current through the ceramic material goes down, so that the heater does not provide significant heating.
