PPTC self recovery fuse
Self restoring fuse PPTC is an overcurrent electronic protection element, which is made of high molecular organic polymer under the conditions of high pressure, high temperature and vulcanization reaction, mixed with conductive particle material and processed by special process. Self recovery fuse (PPTC: polymer self recovery fuse) is a positive temperature coefficient polymer thermistor, which is used for overcurrent protection and can replace current fuse. When the circuit works normally, its resistance value is very small (voltage drop is very small). When the circuit has overcurrent and its temperature rises, the resistance value increases sharply by several orders of magnitude, reducing the current in the circuit below the safe value, so as to protect the subsequent circuit. After the overcurrent disappears, it will automatically return to the low resistance value.
