PTC heating piece heats PTC thermistor
WMZ5 constant temperature heating PTC thermistor has constant temperature heating characteristics. The principle is that after the PTC thermistor is powered on, it self-heats and the resistance value enters the transition zone. The surface temperature of the constant temperature heating PTC thermistor will maintain a constant value. This temperature is only related to The Curie temperature of PTC thermistor is related to the applied voltage and has basically nothing to do with the ambient temperature.

Constant temperature heating type PTC thermistor
WMZ5 constant temperature heating PTC thermistor has constant temperature heating characteristics. The principle is that after the PTC thermistor is powered on, it self-heats and the resistance value enters the transition zone. The surface temperature of the constant temperature heating PTC thermistor will maintain a constant value. This temperature is only related to The Curie temperature of PTC thermistor is related to the applied voltage and has basically nothing to do with the ambient temperature.
PTC heater is a heating device designed using the constant temperature heating characteristics of PTC thermistor. In small and medium power heating situations, PTC heater has constant temperature heating, no open flame, high heat conversion rate, minimal influence on power supply voltage, and long natural life. With advantages that traditional heating elements cannot match, their application in electric heating appliances is increasingly favored by R&D engineers.
Constant temperature heating PTC thermistors can be made into a variety of shapes and structures and different specifications. Common ones include disc shape, rectangle, strip shape, ring shape, honeycomb porous shape, etc. The above-mentioned PTC heating elements and metal components can be combined to form Various forms of high-power PTC heaters
