Introduction to NTC Thermistors: Temperature Sensors

NTC thermistors or negative temperature coefficient thermistors are temperature sensors used in various electronic and control devices. NTC thermistors provide electrical resistance values that depend on the temperature, and thus enable the measurement or control of temperature in a relatively cost effective manner. In comparison with other temperature sensing elements, NTC thermistors have the advantages of an extremely rapid response, a small physical size, and a wide temperature range.

The MM104R1K: A Common NTC Thermistor For Temperature Sensing

The MM104R1K is one of the most commonly used NTC thermistors for temperature sensing applications. It is designed to offer stable and repeatable resistance characteristics with a working temperature range of -40 to 200°C. It is composed of a ceramic body wrapped with a metal electrode and is small and lightweight, allowing for easy integration into most any device.

NTC Thermistors: Operating Principle

The working principle of NTC thermistors is based on the following. When a temperature change occurs in the environment, the resistance of the thermistor will change accordingly, thus allowing for the measurement of temperature. This temperature-dependent change in resistance is non-linear in nature. This means that the resistance of the thermometer will not correspond liningly with the temperature - as the temperature changes, the resistance will change with a non-linear curve.

The MM104R1K Application Field

Given its small size, stability, and temperature range, the MM104R1K is a popular choice for a wide range of temperature sensing applications. One of the most popular areas of application for the MM104R1K is in consumer electronics, where it is used to measure and control the temperature of a variety of products such as refrigerators, air conditioners, and microwave ovens. This thermistor is also used in medical applications, such as monitoring patient body temperatures, and industrial and automotive sensing applications.

Conclusion

The MM104R1K is a popular choice of NTC thermistor for a variety of temperature sensing applications. Its small size and highly stable resistance characteristics make it ideal for applications where robust and accurate temperature sensing is required. Additionally, its wide temperature range and non-linear resistance change make it suitable for a variety of sensing applications, from consumer products to medical and automotive use.
