Temperature Sensors - NTC Thermistors

NTC Thermistors are temperature sensing elements, which are negative temperature coefficient thermistors consisting of a sintered bead of ceramic material. The resistance of thermistors is very sensitive to temperature changes, and they can be used over a wide temperature range. One such example is the NC12L00153MBB thermistor from Murata.

Application Field

NTC Thermistors like NC12L00153MBB are widely used for temperature control, temperature measurement, temperature compensation and temperature protection applications. They are especially useful in applications where high accuracy and reliability of the temperature sensing is required. Possible applications include medical equipment, automotive electronics, industrial heating and cooling systems, domestic appliances, and more.

Working Principle

The working principle of an NTC thermistor is based on the temperature dependent resistivity of a sintered ceramic material. The material is composed of metal oxides with strong covalent bonds. As temperature increases this material\'s resistivity decreases, therefore the resistance of the thermistor decreases. This resistance can be measured and used to calculate the temperature with the relation R = (R25/βT). Here R is the resistance of the thermistor at temperature T, R25 is the resistance of the thermistor at 25°C and βT is a B-value constant determined by the thermistor manufacturer.

Conclusion

The NC12L00153MBB thermistor is a popular NTC Thermistor element with a wide range of applications in temperature sensing applications. The thermistor has a temperature dependent resistivity, which results in decreasing resistance with increasing temperatures. The resistance can be measured from the thermistor using the relation R = (R25/βT).
