Temperature Sensors – NTC Thermistors are electronic devices used to measure temperature. The B57234S0220M051 is a one of such device used for temperature measurement.
Fundamentally, an NTC thermistor performs as a three-terminal voltage dependent resistor. It is inherently a nonlinear device as its resistance changes significantly with temperature, with a negative differential resistance region. The thermistor has an electrical resistance that varies significantly with temperature and the resistance value can typically vary by a factor of 10 or more over a range of 60°C.
Today, NTC thermistors are widely used in various temperature-sensing applications, such as temperature control systems and automotive temperature control systems. They can also be used in various types of sensors, for example for performing temperature measurements on indoors spaces, in weather monitoring, in medical equipment and even in telecommunications.
The B57234S0220M051, specifically, is a commercial type of NTC thermistor. It is an unmounted device in surface mount-base package. It is made of metal semiconductor ceramics and rated for power dissipation of 1 W.
When it comes to its applications, the B57234S0220M051 is suitable for temperature measurements in various applications such as power supplies, computers, industrial machineries, and domestic appliances. It can also be used as a temperature sensor in automotive engines, heat exchangers, air conditioners, and dryers.
To understand the working principle of the B57234S0220M051, we need to understand the basics of thermistors. A thermistor works on the principle of thermal conductance, meaning it relies on the temperature-dependent resistance of a semiconductor material. The electrical resistance of an NTC thermistor is basically inversely proportional to its temperature.
In the B57234S0220M051, heat absorbed is conducted from the surface and through the thermistor material. This generates a variable voltage that is proportional to the temperature. The voltage generated is measured and this reading can be used to determine the temperature.
In an NTC thermistor, the resistance decreases as the temperature increases due to the nature of the semiconductor material used in its construction. This means that it acts as a temperature-dependent thermistor in which the resistance and temperature have an inverse relationship – i.e. as the temperature increases, the resistance decreases and vice-versa.
In conclusion, the B57234S0220M051 is a NTC thermistor often used in temperature sensing applications. It is a unmounted device in surface mount-base package and rated for power dissipation of 1 Watt. This thermistor has a large temperature range 60°C, and is suitable for temperature measurements in various applications such as power supplies, computers, industrial machineries, and domestic appliances. Working wise, the thermistor works on the principle of thermal conductance, wherein heat absorbed is conducted from the surface and through the thermistor material resulting in variable voltage that is proportional to the temperature.
