Temperature Sensors - NTC Thermistors

An NTC thermistor, also known as a Negative Temperature Coefficient Thermistor, is a thermistor that is temperature-sensing electrical resistor with a negative temperature coefficient of resistance. The resistance of an NTC thermistor decreases with an increase in temperature--hence the name negative temperature coefficient. The ABNTC-0603-333J-4050F-T is one example of an NTC thermistor.

Application Field

NTC thermistors are used in a wide range of applications due to their fast response time and reasonable cost. Some of the application areas where NTC thermistors might be used include automotive temperature sensing, health and safety, home appliances, laboratory applications, and more. As an example, NTC thermistors can be used as temperature limiters in cookers, grills, and deep-fryers to prevent overheating. NTC thermistors can also be used in dishwashers and washing machines to monitor water temperature.

Working Principle

The working principle of an NTC thermistor is based on the principle of negative temperature coefficient. An NTC thermistor is made of a sintered mixture of semiconductor material, which is usually made of metal oxides such as manganese, nickel, and cobalt. The resistance of the thermistor increases as the temperature decreases, and vice versa. The resistance of an NTC thermistor is highest at low temperatures, and decreases as the temperature rises.

When an NTC thermistor is exposed to a changing temperature, it also changes its resistance. This change is due to the varying conductivity of the semiconductor material, which changes with the temperature. This changing resistance can be used to measure and detect a temperature change, and is the working principle of an NTC thermistor.

Conclusion

The ABNTC-0603-333J-4050F-T is an example of a Negative Temperature Coefficient (NTC) thermistor. An NTC thermistor is a temperature-sensing electrical resistor that has a negative temperature coefficient of resistance and can be used to measure and detect a temperature change. NTC thermistors find use in a wide range of applications, including automotive temperature sensing, health and safety, home appliances, and laboratory applications.
