PTC, positive temperature coefficient, is a term used to describe the resistance characteristics of ceramic thermistor heating elements and . PTC heating elements have a large positive temperature coefficient of resistance, which means if a constant voltage is applied, the element produces a large amount of heat when its temperature is low, and a smaller amount of heat when its temperature is high. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. items description on the item page. Add to Cart. If the ambient temperature rises, the resistance rises and less current flows. I doubt they chose to have a PTC heating element - rather they had little choice as most metals and alloys have a positive temperature coefficient. A large surface area means the element can operate at a lower temperature and still deliver a large amount of heat. DBK USA has experts standing by to answer your questions. When the power switch is closed and the charging process starts, the uncharged capacitor is like a short circuit and therefore draws a very high inrush current.
