If you’re not deeply invested in knowledge on the components of electronic products, you may not know what a thermistor is.

To help you understand more about this valuable component, this post will cover not only what a thermistor is, but also some of the industries they are often used and what they do in products provided by the industry.


A thermistor is a piece of metal combined with elements such as semiconductor and temperature-sensing materials, to detect and measure hot and cold temperatures. The thermistor can then relay the temperature information to another platform to help communicate the temperature or needed actions to the user. MF72 NTC Thermistor is one of the most common electronic components. Used for Conversion power-supply.

By now you’re probably wondering what electronic products use thermistors and how they are used in the products. Continue reading to learn more.


Vehicles are very important to our everyday lives. Without them, we wouldn’t be able to get to work, go on vacation, or visit our family members. Vehicles are made up of very important and highly-sensitive parts, one of which being the engine.

In the automotive industry, thermistors are used to measure the heat of the engine. The information is then displayed on the car’s dashboard to alert the driver if the vehicle is overheating.


You likely use a microwave to reheat your food when it gets cold. But, did you know that the thermistor is an essential element to the function of your microwave? The thermistor is used to maintain the needed internal temperature based on the heat setting the user configures.

Other kitchen appliances that use thermistors can include things like waffle irons and other heat-conducting kitchen aids.


Energy can be a very dangerous element to work with. Many people run the risk of overusing their power outlets and causing power outages and even house fires.

One way to prevent overheating and electricity fires includes the use of a surge protector. In the case of a power surge, which usually happens when an excess of energy is being fed to the thing that is plugged in, a surge protector with thermistors help to control the surge and limit damage to the electronic and to power source in general.


Home is supposed to be the most comfortable place to be. Part of having a comfortable home is controlling the temperature. Thermistors help to regulate and detect temperature changes in the customer’s home and send the information to a digital thermometer. The customer can then change the temperature to fit their needs and preference with the help of the thermistor.
