Detailed Product Description

Automobile Air Conditioner Thermistor TPE Temperature Sensor 2.2k Ohm 3950

Description Of The Automobile Air Conditioner Thermistor TPE Temperature Sensor

It is usually installed in the temperature sensor package, which can also be said to be an evaporator temperature sensor. When the temperature drops to a certain level, the compressor needs to be shut down, otherwise it will be frosted and eventually form an ice block.
