Constant temperature heating PTC thermistor has constant temperature heating characteristics, the principle is that PTC thermistor after power-on self-heating temperature into the transition zone, constant temperature heating PTC thermistor surface temperature will maintain a constant value, the temperature is only related to the PTC thermistor Curie temperature and applied voltage, and basically unrelated to the ambient temperature.
PTC heating element is a heating element designed by using constant temperature heating PTC thermistor constant temperature heating characteristics. In small and medium-power heating occasions, PTC heating elements have the advantages of constant temperature heating, no open flame, high thermal conversion rate, minimal influence by power supply voltage, long natural life and other advantages that traditional heating elements cannot match, and their application in electric heating appliances is increasingly favored by R&D engineers.
