NTC thermistor models and parameters, how to wire NTC thermistors 1

The NTC thermistor is a temperature-sensitive ATMEGA48PA-PU resistor whose resistance changes with temperature. NTC stands for Negative Temperature Coefficient, meaning the resistance decreases as the temperature rises. NTC thermistors are widely used in temperature detection, temperature compensation, overcurrent protection, and self-resetting fuses. Different application environments and requirements dictate varying model and parameter specifications for NTC thermistors.diode

NTC thermistors are made from semiconductor materials (typically manganese dioxide, copper oxide, iron oxide, silicon, etc.), whose resistivity decreases with increasing temperature. At the microscopic level, rising temperatures increase the number of charge carriers (free electrons and holes) within the semiconductor, enhancing current mobility and consequently reducing the overall resistance value. This property enables NTC thermistors to serve as highly sensitive indicators of temperature.diode
