Self-controlled regulating heat resistors
Often it is necessary to heat large surfaces or specific spots of systems or components. Expensive SMD resistors are frequently used that absorb an especially large amount of power, but often cannot be controlled. A heating resistor can be used directly for the controlled conversion of electrical energy to heat.
A resistor paste with PTC (positive temperature coefficient) is used in most cases for self-regulating heating resistors. Paste systems with a non-linear positive temperature coefficient can be used to create heating surfaces; their resistance characteristics make them self-regulating.
With the right engineering, you can create heating that attains a specific surface temperature (for example, 60 °C) and self-regulates to reduce the heating output, thus keeping the temperature constant.
We will gladly run a feasibility study for you and organize the design details of your specific heating resistors. Please contact us at flatcomp@we-online.de
Examples of practical applications:
- Mirror heaters in motor vehicles
- Prevention of condensation in electronic devices that are subject to significant changes in ambient temperatures
