Temperature Sensors - NTC Thermistors

NTC thermistors are used in a variety of applications to sense and/or measure temperature. Since their earliest application in an automobile starting motor in 1923, their uses have expanded to many other products including consumer electronics, medical devices, household appliances, as well as tough industrial and commercial applications. The MF52C1503F3950 is an NTC thermistor with many useful applications.

This thermistor is manufactured using a metal/silicon/epoxy mixture and a special semicontinuous sintering process, making it well-suited for applications requiring good temperature stability. Its resistance decreases as temperature increases and is available with various resistance values, typically ranging from 50 Ω to 15 kΩ depending on its nominal temperature. The MF52C1503F3950 features good electrical characteristics, excellent stability and accuracy, fast response time, and high repeatability.

In terms of applications, the MF52C1503F3950 NTC thermistor is used in a wide range of temperature sensing and measuring applications, such as: air conditioning, refrigeration, cooking, heating, and air quality control systems; medical devices, such as body temperature sensors or temperature monitoring systems; laboratory instruments, such as pH meters; and as a temperature switch in many industrial processes. Generally, they are used for temperature compensation, temperature control, over temperature protection, and pulse-by-pulse current limiting.

The MF52C1503F3950 also has various working principles. Its resistance decreases when temperature increases, and increases when temperature decreases, following the Arrhenius equation. The resistance of an NTC thermistor is influenced by the thermal energy of its surroundings, and the temperature is related to the resistance by the exponential voltage-current law, which can be expressed as:

T = [A + B*lns(R/Ro)]/C

Where T is the absolute temperature in Kelvin, A, B, and C are the thermistor\'s coefficients, R is the thermistor\'s resistance, and Ro is the reference resistance. Thus, by measuring the thermistor\'s resistance, its temperature can be determined.

Depending on their resistance, their inner structure, and the materials they are made from, NTC thermistors have many different configuration options. The MF52C1503F3950 specifically offers a wide range of products with various voltage ratings, resistance values, and environmental conditions. This makes it suitable for many temperature sensing and measuring tasks, with great stability and accuracy.
