NTC is a semiconductor ceramic device made of manganese, copper, silicon, cobalt, iron, nickel, zinc and other metal oxides through thorough mixing, molding, sintering and other processes; it is used to suppress the surge current of the charger when it is connected to the power supply. NTC is used in series on the circuit. At normal temperature, the zero-power resistance of NTC is relatively large. When the circuit is turned on, it can effectively suppress the startup surge current; and after completing the suppression of the surge current, the continuous effect of the current is used , reducing the resistance value of the NTC thermistor to a very small extent will not affect the normal operation of the circuit.

As a leader in the field of circuit protection, SOCAY Electronics （www.socay.com）has experience in the application of a variety of circuit protection components. In order to protect the PD fast charging charger from damage by current surges, SOCAY launched the NTC negative temperature coefficient thermistor. This device is a plug-in package with high power, large working current and easy welding.
