Temperature Sensors - NTC Thermistors are electrical components that are designed to measure temperature and analyze the relationship between temperature and electrical resistance. Among them, B57421V2103J072 is a typical NTC thermistor that is widely used in numerous applications. This paper will provide a comprehensive discussion on its application field and working principle.

The B57421V2103J072 thermistor offers a wide operating temperature range of -55 to +125°C and a relatively low resistance of 150 Ohms at 25°C. It can be used to measure a wide range of temperatures so it is suitable for many applications. Hence, it is often employed in the temperature monitoring systems of power electronics and photovoltaic systems, automotive electronics, data acquisition systems, and HVAC systems. Additionally, the thermistor can be used as an over-temperature protection device for motors, home appliances, as well as indoor and outdoor equipment.

In terms of its working principle, B57421V2103J072 features an NTC thermistors configuration. In simple terms, an NTC thermistor comprises two crucial components: a metal oxide ceramic body and two or more pins. Thanks to its low resistance, when a voltage is applied to the pins of the thermistor, it enables the electrons captured in the metal oxide to transition between energy states. This generates a flow of electrical current through the device, which can be used to determine the external temperature.

Moreover, the resistance-temperature relationship of B57421V2103J072 follows an inverse exponential curve. This means that as the temperature increases, the resistance of the thermistor decreases. On the other hand, a decrease in temperature will result in an increase in resistance. By analyzing the resistance-temperature relationship of the thermistor, it is possible to accurately measure the temperature of a specific environment.

Since its introduction, the B57421V2103J072 thermistor has become an integral part of temperature-measuring and monitoring applications. Thanks to its sturdy construction and wide operating temperature range, it offers reliable and accurate temperature readings. With its ability to measure temperatures within the range of -55 to +125°C and resistance values as low as 150 Ohms at 25°C, B57421V2103J072 is the perfect choice for a wide range of industrial and commercial applications.
