Heating elements made with PTC chips do not use resistance wire as a source of heat. Instead, it uses a number of ceramic PTC chips as the heating source. PTC heating elements are ceramic chips that have self-limiting temperature characteristics. As the PTC chips heat up it reaches a designed temperature at which the heat output decreases drastically and prohibits it from getting hotter. As ambient temperature increases and less heat is dissipated, the resistance of the element will increase culminating in a near zero current draw at its designated temperature.
The dynamic resistance and output of PTC heaters makes them an excellent choice for providing controlled electric heating. In many applications it is possible to do away entirely with thermostatic controls. Simplification of design and reduced energy consumption represent significant cost savings for a given application. The removal of failure prone components such as thermostats can also add significantly to the reliability of a product. Safety is an added benefit, since no matter how much current is applied to the PTC; it will never surpass its intended surface temperature.
