NTC thermistors, or negative temperature coefficient thermistors, are a type of temperature sensor. As their name implies, these sensors are designed to have their electrical resistance decrease as the temperature rises. The specific NTC thermistor in question, AA6B4-GC11KA143L/37C, is designed for temperature measurement in the range of −40 to +105°C (−40 to 221°F).

The main body of the thermistor is made from a solid material whose electrical resistance decreases as temperature increases. Typically, this material is a ceramic, such as sintered metal oxides, which has been mixed with an appropriate dopant, such as cobalt, nickel, manganese, or copper-constantan. The specific material used in this thermistor is proprietary, as is the rate of change in resistance with temperature.

When exposed to changing temperatures, the thermistor’s resistance also changes. When current flows through the thermistor, a voltage drop proportional to the resistance is created across it. The relationship between the thermistor’s resistance and the temperature can be determined. The AA6B4-GC11KA143L/37C thermistor has a resistance/temperature characteristic of -3950Ω/°C.

As with any other temperature measurement technique, certain factors must be taken into account when using an NTC thermistor. These include the self-heat generated by the thermistor itself, the power supply used, and the electrical source impedances or capacitance, among other factors. Additionally, the rate of change of the thermistor’s resistance with temperature must be factored in when calculating its accuracy.

The AA6B4-GC11KA143L/37C is a popular thermistor amongst many different industries. It is used in medical equipment, lighting, automotive electronics, refrigeration equipment, consumer electronics, industrial automations systems, and process controllers such as controllers for ovens and furnaces, as well as many others.

The AA6B4-GC11KA143L/37C’s simple design and high accuracy make it an effective choice for a wide range of temperature measurement applications. Its low-cost and compact size ensure that it is a robust and reliable option, even in tight spaces. Additionally, its high reliability allows it to withstand the harsh environment of many industrial applications with ease.

Overall, the AA6B4-GC11KA143L/37C is an excellent device for temperature sensing, offering a high degree of accuracy and reliability. Its low-cost and simple design enable it to be integrated into a variety of different systems, making it suitable for many different industrial applications.
