In regions with higher latitude, cold and icy weather is more common. Heated applications have become necessary and more popular. As heating technology varies, positive temperature coefficient (PTC) heating elements can be an ideal solution for automotive integration. PTC heating film is flexible, thin, which can be easily integrated within limited space. Its unique characteristic of self-regulating can keep constant heat on specific temperature when powered, meaning no need to worry about overheating and without the need of temperature controlling module.
