The full form of NTC is a Negative Temperature Coefficient. It refers to a particular sort of thermistor, a temperature-sensitive resistor. Because of their capacity to sense and record temperature changes precisely, NTC thermistors are widely employed in a wide range of applications. What distinguishes NTC thermistors is their inverse relationship between resistance and temperature.

NTC Thermistors Function

In addition, the electrical resistance of NTC thermistors reduces as the temperature rises. This is the inverse of Positive Temperature Coefficient (PTC) thermistors, in which resistance increases as temperature rises. To achieve the requisite negative temperature coefficient behaviour, NTC thermistors are produced from semiconductor materials with carefully regulated doping.

NTC Thermistors in Action

1. Temperature Sensing and Control: Manufacturers widely utilize NTC thermistors in temperature sensors for domestic appliances, industrial machinery, and automotive applications. They are critical in maintaining precise temperature regulation and protecting against overheating.

HVAC systems use NTC thermistors to monitor room temperatures, enabling effective and comfortable climate control.

4. Medical Devices: Medical devices use NTC thermistors to measure and maintain accurate body and environmental temperatures in a variety of applications, including digital thermometers, incubators, and infusion pumps.

5. Consumer Electronics: Electronic devices such as laptops, cell phones, and other gadgets use NTC thermistors to manage interior temperature and protect delicate components.


Hence, NTC or Negative Temperature Coefficient is an important term in temperature sensing and regulation. Its entire form exposes its unique property of lowering resistance with rising temperature. NTC thermistors’ vast range of applications emphasises their relevance in modern technology, from domestic appliances to advanced medical devices and beyond. When you come across NTC in technical language, you will be able to clearly comprehend its meaning and appreciate its role in making our lives safer and more comfortable.
