Heater

Positive Temperature Coefficient (PTC) heaters are self-regulating heaters that run open-loop without any external diagnostic controls. While traditional fixed-resistance heaters employ wires and coils to generate heat, PTC heaters use conductive inks printed on thin, flexible polymer-based substrates. Scoring high on reliability and efficiency, they are ideal for products that require safer, faster and more uniform heating. The properties of the material allow the PTC heater to act as its own sensor, eliminating the need for any external feedback controls. As a result, the heater inherently eliminates the risk of overheating.

PTC heaters utilize Positive Temperature Coefficient materials i.e. materials that exhibit a positive resistance change in response to the increase in temperature. As the temperature increases, the electrical resistance of the material also increases, thus limiting the current flow. Simply put, the material allows current to pass when it’s cold, and restricts current to flow as the threshold temperature increases.
