The corresponding relationship between the resistance value of NTC thermistor and temperature changes is: the thermistor of the negative temperature coefficient, which changes to the inverse relationship with the temperature change, that is, the smaller the temperature high resistance.
The thermistor will be in an unwanted state for a long time; when the ambient temperature and current are in Zone C, the heat dissipation power of the thermistor is close to the thermal power, so the action may not move.
When the thermistor is the same as the ambient temperature, the action time is shortened with the current increase; when the thermistor has a shorter action time and the smaller maintenance current and action current when the ambient temperature is relatively high.
