The Role of Thermistors in Different Products

Feb. 18, 2022

A thermistor is a sensor resistor whose resistance value changes with temperature. According to the different temperature coefficients, it is divided into positive temperature coefficient thermistors and negative temperature coefficient thermistors. With the development of science and technology, the usage rate of thermistors is getting higher and higher, so what is the role of thermistors in different products?

①Microwave oven. Thermistors are used in microwave ovens to determine and maintain internal temperature. Without the thermistor in a microwave oven, overheating could occur inside the unit, which could lead to a potential fire.

②Circuit protector. If you have a power supply or surge protector in your home or office, you will know that it also contains a thermistor. Without a thermistor in this product, the amount of surge will be uncontrolled and overheating will occur to cause short-circuit.

③Vehicles. Trucks and buses use thermistors to determine the temperature of oil and coolant. The thermistor is connected to an indicator on the vehicle's dashboard so that you know if your car is overheating.

The above content is the usage of thermistor in various fields. When purchasing thermistors, you should choose a regular manufacturer. Dongguan Zhixu Electronic Co., Ltd (JEC) has a complete range of models with guaranteed quality. JEC has over 30 years of manufacturing experience.
