Chip NTC thermistor: 1. Basic knowledge Microstructure and characteristics Types and working principles of NTC Electrical parameters of NTC 2. Sunlord thermistor Temperature sensing type NTC Power type NTC 3. Application Microstructure of NTC thermistor NTC thermistor is made of metal oxides such as manganese, cobalt, nickel and copper as the main materials, and is made by ceramic technology. The ceramic microstructure presents a spinel structure. The conductive method is completely similar to semiconductor materials such as germanium and silicon. When the temperature is low, the number of carriers (electrons and holes) of the oxide material is small, and its resistance value is high; as the temperature rises, the number of carriers increases and its resistance value decreases.
