In recent years, PTC (Positive Temperature Coefficient) heaters have gained immense popularity as an efficient and safe heating solution across various applications. With the evolution of technology and a growing demand for energy-efficient devices, PTC heaters offer a unique alternative to traditional heating methods. In this article, we will explore the functioning, advantages, applications, and considerations related to PTC heaters.

    Working Principle of PTC Heaters

    The unique feature of PTC heaters lies in their use of PTC materials, which exhibit a sharp increase in electrical resistance when heated beyond a certain temperature. Initially, when electricity flows through the PTC material, it generates heat. As the temperature of the material rises, the resistance increases, leading to a reduction in the current flow. This self-regulating mechanism ensures that the heater does not exceed its maximum temperature, thereby enhancing safety.
