Introduction

NTC thermistors are temperature sensors with a negative temperature coefficient (NTC). These devices are used in sensing the temperature in a wide range of applications to measure, control, and regulate temperature. The 123JG1K NTC thermistor is one of the most commonly used temperature sensors for many of these applications. This article will look at the 123JG1K application fields and its working principle.

123JG1K NTC Thermistor overview

NTC thermistors are temperature sensors with a negative temperature coefficient. This means that the resistance of the thermistor decreases as the temperature increases. The 123JG1K NTC thermistor is widely used due to its reliable and accurate measurement abilities. It has a low sensitivity to undesired temperature effects, wide operating temperature range, and is able to handle high-current applications with ease.The 123JG1K is also highly temperature stable, has a higher dielectric strength, and its leads are made from plated copper- all making it a more durable and dependable device. Furthermore, its very low temperature coefficient makes it more cost effective than other temperature sensors.

123JG1K Application fields

The 123JG1K NTC thermistor has a wide range of application fields requiring accurate and reliable temperature sensing. The typical applications of the 123JG1K include:* Home and Industrial Automation: The 123JG1K is commonly used in automation to measure the temperature of ovens, refrigerators, air conditioners, and other appliances. It is a reliable and accurate sensor for these applications.* Telecommunications and IT industries: The 123JG1K is used in telecom and IT systems to measure the temperature of electronic components, such as transistors, integrated circuits, etc.* Automotive industry: In the automotive industry, the 123JG1K is used to detect the operating temperature of engines, transmissions, and other automotive components.* Medical industry: In the medical industry, the 123JG1K is used to detect the temperature of drug storage containers, equipment parts, and liquid components.

123JG1K Working Principle

The 123JG1K NTC thermistor is a temperature-sensitive device. Its resistance decreases as the temperature increases. This is due to the temperature coefficient of the device. The temperature coefficient of an NTC thermistor is a measure of its resistance change with temperature. The higher the temperature coefficient, the greater the resistance change with increasing temperature.The working principle of the 123JG1K NTC thermistor is that its resistance decreases with increasing temperature due to its temperature coefficient. This resistance change is used to measure the temperature. When the resistance of the 123JG1K changes, it produces a voltage change that can be measured to generate a temperature reading.

Conclusion

The 123JG1K NTC thermistor is a versatile and cost-effective temperature sensor used in numerous applications. It is highly accurate and reliable, and is able to measure temperature with excellent sensitivity. Lastly, the 123JG1K working principle is based on its temperature coefficient, which allows it to detect temperature changes with precision.
