PTC (Positive Temperature Coefficient) heaters have gained popularity as a reliable and energy-efficient heating solution. These heaters are widely used in various applications, from household appliances to industrial heating systems. In this article, we will explore the working principle, advantages, and common applications of PTC heaters, along with their safety features that make them an appealing choice for both consumers and manufacturers.

    What is a PTC Heater?

    A PTC heater utilizes a unique material known as Positive Temperature Coefficient ceramic. Unlike traditional heating elements that become hotter with increasing electric current, PTC materials have the opposite behavior. As the temperature of a PTC heater rises, its resistance increases, which naturally limits the amount of current flowing through the heating element. This self-regulating feature is what makes PTC heaters both efficient and safe to use.
