What is PTC?
What is Positive Temperature Coefficient?If a material exhibits a positive temperature coefficient means that as its temperature increased its resistance to current raises proportionately. Initially, the current through these devices will rise sharply with the low resistance but then decrease to zero when the design temperature is reached. During manufacturing these devices are made to reach a specific temperature.
Mechanical and Electrical Design Engineers have been using PTC technology solutions to solve problems in a wide range of industrial applications where improved safety, less complexity, and durability had been issues. There are numerous other advantages that continue to make PTC heaters the number one choice for design engineers.
