The PTC thermistor appeared in 1950, followed by the PTC thermistor with barium titanate as the main material in 1954. The PTC thermistor can be used in industry for temperature measurement and control, also for temperature detection and regulation of a part of the car, and is also used in a large n

Many of you are frustrated with how to clean your PTC Heating Fan. Firstly, you cannot put it directly in water, which makes the cleaning process much more complicated. Secondly, they do not know how to disassemble the PTC Heating Fan, and then they do not know what to pay attention to in the cleani

A PTC is a semiconductor heating ceramic. When the external temperature decreases, the resistance of the PTC decreases and the amount of heat generated increases accordingly. To say that a material has a PTC (Positive Temperature Coefficient) effect means only that the resistance of the material inc
