Temperature Sensors - NTC Thermistors

NTC thermistors, also known as Negative Temperature Coefficient Thermistors, are thermally sensitive semiconductor device that utilizes a variation in resistance as the temperature around it changes. Underlying the functionality is an exponential relationship between the resistance and temperature of the thermistor. This relationship can be exploited for use in various temperature sensing and control applications.

The NC12P00104JBB is a frequently used NTC thermistor with a resistance of 15 kΩ at 25 °C. This thermistor exhibits a negative temperature coefficient (NTC) where the resistance decreases as the temperature increases. The resistance can drop as low as 1.25 kΩ at 100 °C when the thermistor is properly heated. This temperature sensing component is composed of sintered metal nitride semiconductors that can detect electrical pulses accurately.

The thermistor offers an excellent accuracy (1%) at the rated temperatures of 25 °C and 100 °C. In addition, the resistance-temperature curves of this device provide a thermal time constant of ~ 10 seconds. It has a maximum rated operating temperature of up to 400 °C and an operating temperature range from –40 °C to 125 °C. It can operate with a wide variety of non-corrosive liquids and gases over a wide range of temperatures.

The NC12P00104JBB thermistor comes in a TO-92 epoxy molded plastic package with four pins. It works by sensing the temperature of its environment and producing a change in resistance in response. This in turn provides a voltage or current output indicative of the temperature. This type of thermistor is useful for the detection of hot and cold spots, thermal dissipation, human body temperature sensing, and medical thermometer applications.

NTC thermistors such as the NC12P00104JBB offer reliable performance, good accuracy and excellent thermal response. Its compact size and low resistance at 25 °C make it ideal for a variety of temperature sensing and control applications. Its stability over a range of temperatures also improves system accuracy and eliminates the need for recalibration or re-adjustment of application settings, thus providing a reliable and consistent temperature reading.
