What is an NTC thermistor

NTC thermistor are widely used in temperature measurement, overheat protection, current limiting, and many other fields. With their unique temperature-resistance characteristics, they have become key components in many devices and systems. Today, we will take a detailed look at the working principle, applications, and the important role of NTC thermistor in electronic products.

Working principle of NTC thermistor

The working principle of an NTC thermistor is based on the conductive properties of semiconductor materials. It is usually made of metal oxides or other semiconductor materials, whose electrical conductivity changes significantly with temperature. When the temperature rises, the number of free electrons in the material increases, and the resistance value decreases. This characteristic enables NTC thermistors to sense temperature changes and convert them into electrical signals.

Applications of NTC thermistors

Temperature measurement and control: Due to their resistance-temperature characteristics, they are often used in temperature sensors to accurately measure and control the temperature of devices.

Current limiting:

NTC thermistor are also commonly used in power circuits to help limit the startup current. When the power is turned on, the resistance of the NTC thermistor is high, which limits the current. As the device temperature rises, the resistance decreases, allowing the current to flow.

Overheat protection:

NTC thermistors can also be used as overheat protection devices to protect circuits and devices from overheating damage by detecting temperature changes.
