Self-regulating heating resistors 

A heating resistor serves to directly control the conversion of electrical energy to heat. 

Usually a polymer thick film resistor with PTC (Positive Temperature Coefficient) characteristic response is used for heating resistors. This produces a heater with self-control. 

The conductive polymer thick-film available has a logarithmic temperature characteristic. 

Given the right engineering, a heater can be produced achieving a defined surface temperature (for example 60 °C) as the heating power reduced by self-control. 

Applications: 

• Car mirror heating  
• Avoiding condensation on electronic devices with dynamic temperature changes.
