Temperature Sensors—NTC Thermistors

Thermistors are solid-state temperature sensors that are made of a ceramic material consisting of sintered metal oxides. They contain a metal oxide material whose resistance is sensitive to temperature increase or decrease. While the resistance of standard resistors generally decrease with temperature, thermistors show an increase in resistance. This means that if the current through the thermistor is kept constant, the voltage drop across it will increase as temperature increases.

The BR42KA102M is a thermistor manufactured using NTC (Negative Temperature Coefficient) thermistor technology. It is typically used in applications such as temperature measurement, temperature compensation, over-temperature protection, and thermoelectric cooling. It has good accuracy and high sensitivity, making it well-suited to applications that require precise and reliable temperature sensing. The thermistor is composed of a dielectric ceramic composed of a resistive layer, a positive temperature coefficient layer, and a negative temperature coefficient layer. The resistance of the thermistor varies based on the temperature, so that it acts as a temperature sensor.

The working principle of the BR42KA102M is relatively simple. It consists of a silicon semiconductor chip that is connected to two terminal pins. When temperature changes, the resistance of the semiconductor chip changes. This resistance change is then converted to an equivalent voltage which can be read by a control system. The voltage range of the BR42KA102M is from −25°C to 150°C, with a resistance range of 0.1KΩ to 1MΩ.

The advantage of using the BR42KA102M is that it is a very reliable, accurate and linear sensor. It is also simple to install and easy to operate. Additionally, the Thermistor has a wide temperature range and a long product life. The BR42KA102M is suitable for a variety of different applications such as temperature compensation, over-temperature protection, and thermoelectric cooling.

The BR42KA102M is also cost-effective, relatively low-priced and highly accurate. It is suitable for long-term or high-temperature applications, providing many years of reliable and precise temperature sensing. The BR42KA102M thermistor is also RoHS compliant and UL and CE certified, making it a popular choice for applications that require reliable operation in harsh environments.

In conclusion, the BR42KA102M is a reliable and accurate thermistor which can be used in a variety of applications such as temperature measurement, temperature compensation, over-temperature protection, and thermoelectric cooling. It is RoHS compliant, UL and CE certified, making it a popular choice for applications that require reliable operation in harsh environments. The BR42KA102M is a cost effective solution for temperature sensing and has good accuracy and high sensitivity, making it well-suited to applications that require precise and reliable temperature sensing.
