Introduction

NTC thermistors, also known as negative temperature coefficient thermistors, are temperature sensors designed to detect and measure a wide range of temperatures. The MM203J1K is a type of NTC thermistor. This thermistor is suitable for a variety of temperature sensing and monitoring applications. This article provides an overview of the application fields and working principle of the MM203J1K.

Application Fields

The MM203J1K is a wide operating temperature NTC thermistor which is suitable for use in a variety of applications, including refrigeration and air conditioning systems, temperature control and monitoring, over temperature protection, HVAC systems, solid state relays, etc.In addition to its various application fields, the MM203J1K also has a wide operating temperature range ( -55℃ to +125℃ ). This makes it suitable for use in a variety of environments, from extreme cold to extreme heat. Furthermore, the MM203J1K features a high resistance-temperature coefficient, allowing for accurate temperature readings.

Working Principle

The MM203J1K is an NTC thermistor, which is a type of temperature sensor. The working principle of the MM203J1K is based on the fact that as the temperature of the thermistor increases, its electrical resistance decreases, and vice versa.When a voltage is applied to the thermistor, the current flowing through the thermistor can be determined by measuring the voltage across the thermistor. From this voltage, the thermistor’s resistance can be calculated. Knowing the thermistor’s resistance allows us to determine its temperature.

Conclusion

In conclusion, the MM203J1K is an NTC thermistor which is suitable for a variety of temperature sensing and monitoring applications. It is suitable for use in a variety of environments due to its wide operating temperature range. The working principle of the MM203J1K is based on the fact that as the temperature increases, its resistance decreases. With this thermistor, accurate temperature readings can be obtained.
