Introduction to B57891M0104H000

B57891M0104H000 is an NTC thermistor, more specifically a negative temperature coefficient thermistor. NTC thermistors are thermally sensitive semiconductor resistors, which offer a precise way to measure temperature. B57891M0104H000 is produced by Infineon Technologies, it is based on semiconductor material. B57891M0104H000 features include a RoHS compliant portfolio, temperature ranges between -20°C and +100°C and resistance range with 1.2 kOhm.

Application Field of B57891M0104H000

As with all NTC Thermistors, the B57891M0104H000 is a widely used component for temperature control and temperature monitoring. Specifically, the B57891M0104H000 can be found in industrial, medical, and consumer electronics applications such as heaters or ovens, thermally regulated circuits, temperature detection and temperature control systems. Additionally, since NTC thermistors are linear over a wide range of temperatures, they are used in deriving voltage reference sources.

The B57891M0104H000 is also used in more specialized applications. For example, the B57891M0104H000 is used to detect temperature changes in automotive applications, such as engine coolant levels and engine running temperatures. It is also used in refrigeration, medical and HVAC systems. Additionally, B57891M0104H000 is used to detect the temperature of components in data centers and servers.

Working Principle Of B57891M0104H000

B57891M0104H000 is an NTC thermistor which means that resistance decreases in response to an increase in temperature. This is known as a negative temperature coefficient. B57891M0104H000 is made up of a semiconductor material with a high Curie temperature, which is the temperature at which the material reverses its temperature coefficient from negative to positive. As the temperature increases above this point, the thermistor\'s resistance decreases further.

The working principle of the thermistor is simple; as the temperature increases the resistance decreases. This can be seen by connecting the thermistor in series to a known voltage. When the temperature changes, the resistance of the thermistor will in turn also change, resulting in a change in the voltage across the thermistor, which can be measured by a voltmeter.

When the thermistor is used in a closed loop control system, the temperature to which the thermistor is exposed to will vary until it has reached a predetermined set point, after which the system will stabilize. A temperature controller or regulator is often used to monitor and adjust the temperature as required. It will be able to detect a difference between the actual temperature and the desired temperature and then adjust in order to reach that desired temperature.

Conclusion

The B57891M0104H000 NTC thermistor is a widely used temperature sensing device and can be found in a number of applications. Its working principle is based on the property of semi-conductors, where resistance decreases in response to an increase in temperature. This allows temperature to be monitored and controlled accurately in a closed loop system.
