PTC Thermistor for Constant Temperature Heating

Product Overview
The constant temperature heating characteristics of the PTC thermistor for constant temperature heating are determined by the material properties. The principle is that when the PTC thermistor is powered on, the temperature of the component body rises due to self-heating, the resistance value enters the transition zone, and the current drops rapidly, so the surface temperature of the constant temperature heating PTC thermistor continues to maintain a constant value. This temperature is only related to the Curie temperature and the applied voltage of the PTC thermistor, and has little to do with the ambient temperature.
The PTC constant temperature heater is a heating device designed using the constant temperature heating characteristics of the constant temperature heating PTC thermistor. In small and medium power heating occasions, the PTC heater has advantages that traditional heating elements cannot match, such as constant temperature heating, no open flame, high heat conversion rate, minimal influence by power supply voltage, and long natural life. Its application in electric heating appliances is increasingly favored by R&D engineers.
The constant temperature heating PTC thermistor can be made into a variety of shapes and structures and different specifications. Common ones are disc, rectangle, strip, ring, and honeycomb porous. Combining the above-mentioned PTC heating elements and metal components can form various forms of high-power PTC heaters.

Model parameters

Aluminum shell type PTC heater
Appearance and structure

Model parameters

According to customer requirements, the temperature can be designed between 60℃~280℃, and the operating voltage can be designed between 12V~240V.
Usage Notes
1) The heating power decreases from large to small after power is turned on, and finally stabilizes. The stable power is related to the use conditions. The same PTC heater may have several times different power under different use conditions. The faster the heat dissipation, the greater the stable power; the higher the surface temperature of the PTC, the higher the power.
2) The surface temperature of the PTC heating element is controlled by the PTC itself, and can also be controlled by disconnecting the circuit, but the surface temperature cannot be controlled by adjusting the voltage.
3) The PTC itself has high reliability and long life, but if it is not assembled properly, the product will have unstable power and temperature.
4) When multiple PTCs are used together, they should be connected in parallel, not in series.
