Temperature Sensors - NTC Thermistors

NTC thermistors are thermally sensitive resistors whose resistance is inversely proportional to temperature. They are widely used for temperature measurement and temperature control. TO103J2K-RA is one such temperature sensor, and it is a high precision, long life, NTC thermistor.

Application Fields

TO103J2K-RA NTC thermistor is used in many applications, particularly in the areas of process monitoring and control. They are used for temperature sensing in commercial, automotive, and industrial applications, which include, but are not limited to, environmental temperature sensing, medical temperature sensing, automotive temperature sensing, food temperature sensing, and HVAC temperature sensing.

Working Principle

The working principle of a TO103J2K-RA NTC thermistor is based on the principle of thermal resistance. It works by converting a change in temperature into a change in electrical resistance. This change in resistance is then used to calculate the temperature. When the temperature increases, the electrical resistance of the NTC thermistor decreases, and vice versa. The resistance change can be observed between -55°C and 150°C. This wide temperature range makes the TO103J2K-RA a very versatile temperature sensor.The TO103J2K-RA is connected to a circuit that measures the resistance change. This resistance change is then used to calculate the temperature. The TO103J2K-RA is also very accurate. It has a high precision of ±0.3°C and a repeatability of ±0.2°C, making it ideal for temperature measurement and control applications.

Conclusion

The TO103J2K-RA is a high precision, long life, NTC thermistor. It is widely used for temperature measurement and control in commercial, automotive, and industrial applications. It works by converting a change in temperature into a change in electrical resistance, which is then used to calculate the temperature. It has a high precision of ±0.3°C and a repeatability of ±0.2°C, making it ideal for temperature measurement and control applications.
