NTC thermistors are very versatile temperature sensors. The SM105R1K is one of the most widely used NTC thermistors available today and is used in a wide variety of applications. This article will discuss the application fields and working principle of the SM105R1K.

Firstly, we will look at the application fields of the SM105R1K. This thermistor is used in measuring temperature in various environments such as in food processing, home and industrial HVAC/R systems, hospitals and laboratories. It is also used in many industrial applications including in medical equipment, consumer electronics and even data centers.

The SM105R1K thermistor has many advantages that make it suitable for these applications. One of its main advantages is its high accuracy and precision. The thermistor is able to accurately measure temperatures in a wide range of environments and can measure temperatures at a resolution of 0.1°C. Furthermore, this thermistor has a wide operating temperature range (-40°C to 200°C) and is able to measure temperatures outside of this range in extreme cases.

The SM105R1K is also very robust. Its thick glass body and epoxy coating make the thermistor resistant to most chemicals, including acids, bases and solvents. This makes the SM105R1K suitable for a wide range of applications.

Another advantage of the SM105R1K is its fast response time. This thermistor is able to measure temperatures quickly and accurately. This makes it ideal for applications where fast response times are required, such as in food processing or HVAC/R systems.

Finally, the SM105R1K is also cost effective. This thermistor can be bought in bulk, making it suitable for large-scale applications.

Now that we have discussed the application fields of the SM105R1K, let\'s look at its working principle. The SM105R1K is an NTC thermistor. This means that it is a temperature-sensitive resistor that changes resistance when its temperature is changed. When the temperature of the thermistor is increased, its resistance decreases; when the temperature of the thermistor is decreased, its resistance increases.

This change in resistance can be used to measure the temperature. The thermistor is connected to a power supply and the resulting current is measured. This current is then used to calculate the temperature. The accuracy of the measurement depends on the accuracy of the power supply and the sensitivity of the thermistor.

The SM105R1K has a Resistance-Temperature Coefficient (RTC) of 0.73. This means that for every 1 degree Celsius change in temperature, the resistance of the thermistor will change 0.73 units. The SM105R1K also has a resistance range of 4.5MΩ to 25MΩ, meaning that it is able to measure temperatures between -40°C and 200°C accurately.

In conclusion, the SM105R1K thermistor is a versatile and reliable NTC thermistor. It is suitable for a wide range of applications and is able to provide accurate and precise temperature measurements in a wide temperature range. Furthermore, its robust construction and fast response time make it ideal for many applications. All these features make the SM105R1K one of the most popular NTC thermistors available today.
