12 Volt PTC Heaters

PTC Heaters for 12 Volt Circuits Positive temperature coefficient heaters (PTC) are ideal for small places requiring 12 Volt AC/DC power. These micro heaters work at a constant temperature, not requiring additional temperature controls, minimizing circuit components. 12 Volt PTC heaters come in surface, air, or fan heater configurations.  The small PTC ceramic heating element is embedded in the heat conductive case and prewired for connections to the 12-volt circuit.   How does the PTC heater work? The ceramic heating element inside the heater is made by compressing ceramic materials blended for specific characteristics and temperature.  The positive temperature coefficient...

How PTC Heating Element Technology Works

PTC heating elements have several advantages over other types of heating elements. For example, they are much more efficient than resistive heating elements since they only produce heat to the desired temperature and minimize the current or power requirements.

PTC heating elements also have an automated feature that prevents them from overheating. The resistance of the material increases as the temperature rises, which in turn decreases the current flowing through the heating element.
