Introduction:

NTC thermistors are temperature sensors that measure temperature via resistance variations. As temperature increases, resistance falls; as temperature falls, resistance rises. The SM472G1K is a standard NTC thermistor intended for a range of applications.

Specifications:

The SM472G1K has a wide operating temperature range, from -55 ºC to +150 ºC. Its resistance at 25 ºC is 10KΩ, with tolerance of ±1%. The thermal time response is within 30 seconds at a 73% response level. It is made of a glass-nickel material combining the benefits of the two materials. The NTC thermistor is highly stable and reliable, and to ensure the best performance it should be heat sinks in its environment.

Applications:

The SM472G1K is designed for a variety of applications. It can be used for temperature measurement and monitoring in a number of environments. For example, it is frequently used in automotive electronics and home appliances to measure the temperature inside the equipment and adjust it accordingly. This type of thermistor can also be used in industrial process control to ensure safe and efficient operation. Additionally, it can be used for environmental sensing in agricultural and commercial applications such as greenhouses and warehouses.

Working Principle:

The SM472G1K works by using the change in resistance that occurs when temperature changes. As temperature increases, the resistance decreases and vice versa. As a result, the thermistor can be used to measure temperature by monitoring the resistance. The thermistor works by using the semiconductor properties of its material. At low temperatures, electrons are easily able to move around the material, and the resistance is low. As the temperature increases, the electrons have less room to move. As a result, the resistance increases. This thermistor material is also stable, meaning that it can be used to accurately measure temperature and detect even small changes in temperature.

Conclusion:

The SM472G1K is a standard NTC thermistor designed for a wide range of applications. It has a wide operating temperature range, from -55 ℃ to +150 ℃, and its resistance at 25 ℃ is 10KΩ. It is well suited for temperature measurement and monitoring in automotive, home appliance, industrial process and environmental sensing applications. Its working principle involves the semiconductor properties of its material, and the thermistor can accurately detect even very small changes in temperature.
