What is an NTC Thermistor

Among electronic components, NTC thermistors are a very common yet often overlooked small part. Especially NTC thermistors, they play a crucial role in household appliances, automobiles, new energy devices, and more. So, what is an NTC thermistor? What exactly does it do? This article will explain it all to you.


 

I. What is an NTC Thermistor

NTC stands for Negative Temperature Coefficient, which means that the resistance of an NTC thermistor decreases as the temperature rises. The higher the temperature, the lower the resistance.

The unique temperature sensitivity of this type of resistor makes it an important component for temperature detection, temperature compensation, and surge suppression in various electronic devices. Simply put: NTC thermistor = a resistor whose resistance decreases as the temperature increases.
 

II. Working Principle of NTC Thermistors

NTC thermistors are made of semiconductor materials, which have the following characteristics:

At low temperatures, there are few free electrons inside, resulting in high resistance;

As the temperature rises, the number of free electrons increases, and the resistance decreases.

It is precisely because of this property that NTC thermistors can accurately reflect changes in the external environment's temperature and thus play the following roles in circuits:

Temperature detection: Determine the temperature based on resistance changes;

Temperature compensation: Keep the circuit stable at different temperatures;

Surge suppression: Reduce the inrush current when the device starts up, protecting the components.
 

III. How to Choose High-Quality NTC Thermistors

There are many brands of NTC thermistors on the market, with varying qualities. When choosing, pay attention to the following points:
