About NTC
NTC is the abbreviation of Negative Temperature Coefficient, which means negative temperature coefficient. It generally refers to semiconductor materials or components with a large negative temperature coefficient. Usually, the NTC we refer to refers to a negative temperature coefficient thermistor, or NTC thermistor for short. Also known as a negative temperature coefficient thermistor, it is a type of sensor resistor whose resistance value decreases as the temperature increases.
The NTC thermistor is a very simple temperature sensor that is very common in consumer electronics. NTC thermistor is a typical temperature-sensitive semiconductor resistor, and its resistance value decreases step by step as the temperature increases.
NTC thermistors are made of metal oxides such as manganese, cobalt, nickel, and copper as the main materials, and are manufactured using ceramic processes. These metal oxide materials have semiconductor properties because they are completely similar to germanium, silicon, etc. in conductive methods. Semiconductor materials. When the temperature is low, the number of carriers (electrons and holes) of these oxide materials is small, so the resistance value is high; as the temperature increases, the number of carriers increases, so the resistance value decreases.

Thermister NTC Selection methods and Applications
I.Selection methods
Zero power resistance based on maximum operating ambient
temperature.
The maximum steady-state current at the maximum ambient temperature
is greater than the customer's maximum long-term operating current,
with a margin.
II.Applications
Switching power supplies, adapters, PD fast chargers,electronic motors, etc.
