About PPTCs
The Polymeric positive Temperature Coefficient is a kind of overcurrent electronic protection element, which is made of high polymer organic polymer under the condition of high pressure, high temperature and vulcanization reaction, after doping with conductive particle materials and processed by special technology. Traditional fuse overcurrent protection, only can protect once, burned out need to be replaced, while the self-recovery fuse has overcurrent overheating protection, automatic recovery of dual functions.
PPtcs working standard
PPTCs Working Standard
Connected in series to the circuit, when there is an abnormal current, the resistance value rises momentarily and acts as a current limiter. When the abnormal current disappears, it returns to a low resistance state and the circuit operates normally.
