Since the advent of automobiles, NTC thermistor has played a role of temperature monitoring, temperature control and temperature protection in it. The amount of thermistors used in automobiles has also increased from 2 in 1966 to about 60 in the 1990s, and then to about 80 to 100 per car today. Now, as automobiles become more common, NTC thermistors are also being used more than ever before.

With the continuous development of automotive process technology, NTC thermistors are required for air conditioner, car seat heating, car window defrosting, oil thermometers, etc. in automobiles. Compared with other automotive application scenarios, the use of thermistors in automotive air conditioner has a relatively long history and more mature technology. NTC thermistors are placed near the evaporator coils of automotive air conditioner refrigeration systems to monitor the temperature in real time. NTC thermistor feeds the data back to the air conditioning control unit after monitoring the temperature in the car, which adjusts and corrects the temperature in the car, this helps the driver to better adjust the car air conditioner to achieve a comfortable interior temperature.

VT series - automotive NTC thermistor from EXSENSE Electronics Technology Co., Ltd., with characteristics of wide range of using temperature, fast response, high sensitivity, etc.. VT series NTC thermistor plays an important role in automobile by using the principle that its resistance value decreases with the increase of temperature in application scenarios such as automobile air conditioning and car seat heating.
