Introduction

CMFB3435103FNT is a temperature sensor, belonging to the NTC thermistors family. It is a negative temperature coefficient device, with a temperature range of -50°C to +200°C. The main function of the CMFB3435103FNT is to detect and measure temperature changes, providing useful information for heating, cooling, ventilation and many other temperature related applications. This particular device combines good accuracy and fast response with a low cost.Application Field

The CMFB3435103FNT can be used in a wide variety of applications. Its main purpose is for temperature sensing and measurement, as well as temperature control. It can be used in refrigerators, heating systems, air conditioners, ovens, grills, and food warmers, to name a few. It can also be used in medical equipment and automotive applications, such as engine and transmission controls. In all these applications, CMFB3435103FNT provides precise temperature readings, thus allowing for efficient control and monitoring.Working Principle

The CMFB3435103FNT is an NTC thermistor, meaning its resistance decreases in higher temperatures. This effect is due to the negative temperature coefficient of the thermistor and it is the basis of its functionality. The device itself consists of resistive elements, attached to two different conductors. As the temperature changes, so does the resistance of the thermistor, which can then be measured by a corresponding measuring circuit.The reference circuit required to measure the CMFB3435103FNT is usually a Wheatstone bridge or an oscillator. The Wheatstone bridge is the most commonly used circuit for this purpose. The bridge consists of four resistive elements, two fixed resistors and two variable resistors (usually NTC thermistor). As the temperature changes, the resistance of the thermistor changes, thus resulting in a different output voltage in the bridge circuit. This output voltage can then be conditioned and measured to give precise temperature readings.Conclusion

In conclusion, CMFB3435103FNT is a temperature sensor, belonging to the NTC thermistor family. It is widely used in temperature sensing and temperature control applications, such as refrigerators, heating systems, air conditioners, ovens, grills, and food warmers. The main working principle of the CMFB3435103FNT is the negative temperature coefficient effect. This effect causes the resistance of the device to decrease in higher temperatures, thus allowing for precise temperature readings to be obtain from a corresponding reference circuit.
