NTC thermistor model and parameters, how to wire NTC thermistor 1

NTC thermistor is a temperature sensitive ATMEGA48PA-PU resistor, whose resistance value changes with temperature. NTC stands for Negative Temperature Coefficient, which means that the resistance value decreases with increasing temperature. NTC thermistors are widely used in temperature detection, temperature compensation, overcurrent protection, and self-healing fuses. Different application environments and requirements have varying demands for the models and parameters of NTC thermistors.

NTC thermistors are made of semiconductor materials (usually manganese dioxide, copper oxide, iron oxide, silicon, etc.), whose electrical resistivity decreases with increasing temperature. At the microscopic level, an increase in temperature leads to andiode increase in the number of charge carriers (free electrons and holes) inside the semiconductor, thereby increasing the fluidity of the current and causing a decrease in the overall resistance value. This property makes NTC thermistors a very sensitive indicator of temperature.diode
