NTC thermistors are temperature sensors that are often used due to their wide temperature range, high sensitivity and excellent long-term stability. The SM102E1K NTC thermistor is a popular temperature sensor that can be used in many applications.

Features

The SM102E1K NTC thermistor has several features that make it an attractive choice for use in sensing temperature. It has excellent linearity, with a tolerable temperature error of ±2℃. It also has a wide operating temperature range – from -55℃ to +200℃. Additionally, it has fast response time and requires no calibration. It also has an exceptional long-term stability, which is important for reliable temperature measurement.

Application Field

The SM102E1K NTC thermistor is often used in automotive, industrial, medical, and consumer electronics applications. It can be used in sensors for cars, such as temperature sensors in the engine and in HVAC systems. It can also be used in industrial process control devices, such as temperature and humidity sensors. In medical applications, it can be used in biomedical sensors, such as temperature probes in CAT scanners. And in consumer electronics, it can be used in temperature sensors in electronic components, such as microwaves and air conditioners.

Working Principle

The SM102E1K NTC thermistor is a resistance-type temperature sensor. It is made of a metal oxide semiconductor material that has a dinistor effect. As the temperature increases, the resistance of the material decreases. The SM102E1K thermistor has a temperature coefficient of -2.672-mV/K. This means that the resistance of the sensor changes by -2.672 mV per kelvin, or for every 1℃ change in temperature. This change in resistance can be used to measure the temperature.

How to Use?

Using the SM102E1K NTC thermistor is relatively simple. The thermistor is connected to a circuit with two leads (the longer lead is usually the positive lead). The resistance across the two leads varies with temperature, and can be measured by connecting a multimeter to the leads. The multimeter should be set to measure resistance in Ohms, and the resistance reading can then be used to calculate the temperature.

Conclusion

The SM102E1K NTC thermistor is an ideal temperature sensor for a wide range of applications. It has excellent linearity, wide operating temperature range, fast response time, and requires no calibration. Its temperature coefficient of -2.672-mV/K makes it easy to measure temperature with a multimeter. It is sure to provide reliable temperature measurements in a wide variety of applications.
