High Stability Fast Response Vehicle Temperature Sensor Excellent Moisture Resistance
Negative temperature coefficient thermistors are made of metal oxides such as manganese, cobalt, nickel and copper, and are manufactured by ceramic technology. These metal oxide materials all have semiconductor properties, because they are completely similar to semiconductor materials such as germanium and silicon in terms of conductivity. When the temperature is low, the number of carriers (electrons and holes) in these oxide materials is small, so its resistance value is high; as the temperature increases, the number of carriers increases, so the resistance value decreases. The range of NTC thermistor at room temperature is 100~1000000 ohms, and the temperature coefficient is -2[%]~-6.5[%].
►Different NTC thermistor using in the NTC temperature sensors with the following different operating temperature:
Chip or MF52A,MF51E,MF55: temperature resist grade 125℃,actual temperature resist grade 150℃

The main technical parameters:
1. The rated zero-power resistance value R25 refers to the zero-power resistance value of the thermistor measured at 25°C.
2. B value; defined as the ratio of the difference of the natural logarithm of the zero-power resistance value at two temperatures to the difference between the two temperatures.
3. Thermal time constant; under zero power conditions, when the temperature changes suddenly, the time required for the temperature of the thermistor body to change by 63.2% of the temperature difference between the beginning and the end.
4. Dissipation coefficient; at a specified ambient temperature, the ratio of the change in power dissipation of the thermistor to its corresponding temperature change.

Working principle of temperature sensor
Using the NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
