Temperature Sensors - NTC Thermistors

NTC thermistors are widely used to measure temperature by utilizing the temperature sensitive electrical parameters of the thermistor. They are used in many different industries, and the B57891S104H9 is one of the most widely used thermistors. In this article, we will look at the application field and working principle of the B57891S104H9.

Application Field

The application field of the B57891S104H9 is quite broad. Due to its robust design and long lifetime, it is suitable for a wide range of applications, including: automotive, medical, consumer electronics, industrial, measurement and control, military and aerospace, power supply, and many more.

The B57891S104H9 is also used in temperature sensing applications. It is often used in portable temperature sensing systems, such as thermocouples and liquid crystals.

Working Principle

The B57891S104H9 thermistor operates using the principle of resistance-temperature sensing. A thermistor is a semiconductor device whose resistance changes with temperature. As the temperature increases, the resistance of the thermistor increases, and as the temperature decreases, the resistance decreases. This property can be used to measure temperature.

The B57891S104H9 thermistor utilizes a positive temperature coefficient (PTC) thermistor, which is a two-terminal device where the resistance increases with increasing temperature. As such, when the thermistor is exposed to a heat source, the resistance increases, and when it is exposed to a cold source, the resistance decreases. This response to temperature makes the B57891S104H9 thermistor ideal for sensing temperature changes in systems.

Conclusion

The B57891S104H9 thermistor is one of the most widely used thermistors due to its robust design and long lifetime. It has a wide range of applications, including automotive, medical, consumer electronics, industrial, measurement and control, military and aerospace, power supply, and many more. The thermistor operates using the principle of resistance-temperature sensing. When exposed to heat, the resistance of the thermistor increases, and when exposed to cold, the resistance decreases. This makes it ideal for temperature sensing applications.
