What is the PTC effect

The PTC effect is known as the Postive Tempcrature coefficient, which refers to the fact that the resistance of a material increases with temperature, and it increases sharply in a certain temperature range. A material with PTC effect called PTC material means:

A material has a PTC (Positive Temperature Coefficient) effect, that is, a positive temperature coefficient effect, which means that the resistance of the material increases as the temperature increases. For example, most metal materials have PTC effects. In these materials, the PTC effect appears as a linear increase in resistance with increasing temperature, which is what is commonly referred to as a linear PTC effect.

PTC Introduction

PTC is a kind of semiconductor heating ceramics. When the outside temperature decreases, the resistance of PTC will decrease, but the heat will increase accordingly.
