Feature 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, due to self-heating, the temperature of the
component body rises, 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 of the FTE thermistor and the applied voltage, and has little to do with the ambient temperature.
Description
PTC constant temperature heater is a heating device designed by using the constant temperature heating characteristics of constant
temperature heating PTC thermistor. In small and medium power heating occasions, PIC heater has advantages that traditional
heating elements cannot match, such as constant temperature heating, no open flame, high heat conversion rate, minimal influence
of power supply voltage, and long natural life. Its application in electric heating appliances is increasingly favored by R&D
engineers.
Constant temperature heating FTC thermistors can be made into various shapes and specifications, the most common of which are
disc, rectangle, strip, ring, honeycomb porous, etc. Combining the above PTC heating elements and metal components can form
various forms of high-power PTC heaters.
