Temperature Sensors - NTC Thermistors

A NTC thermistor is a temperature-sensing device that exhibits a large change in electrical resistance as the surrounding temperature changes. NJ28MA0502F is an NTC thermistor made of Ceramic and metal materials. This NTC thermistor has a resistance of 50kOhm at room temperature (25°C). As the temperature rises, the resistance decreases.

This NTC thermistor is typically used in temperature sensing applications. It can be used to measure temperature in air, liquids, or surfaces. It is a reliable and accurate sensor for temperature measurement. The temperature range it can measure is from -40 to +150°C.

In addition to temperature sensing applications, this NTC thermistor can also be used in other applications such as over-temperature protection, current sensing, and overload protection, among others. It can be used to detect over-temperature conditions in motor controllers, motors, and other electronic devices.

The operating principle of this thermistor is based on the PTC (positive temperature coefficient), its resistance increases as the temperature goes beyond 25°C.

When the thermistor is exposed to heat, its electrical resistance increases exponentially, and the output voltage is inversely proportional to the temperature.This means that the higher the temperature, the lower the output voltage. This inverse relationship can be used to accurately measure temperature.

In addition, the NTC thermistor\'s sensitivity can be adjusted by changing the coefficient of resistance. This coefficient of resistance determines the sensitivity of the thermistor. By adjusting this coefficient of resistance, the thermistor will be more or less sensitive to temperature changes.

The NTC thermistor is smaller and lighter than other temperature sensors. It has excellent reliability and a long service life. It also offers high accuracy and stability, making it an ideal choice for temperature sensing applications.

The NJ28MA0502F has excellent temperature stability when exposed to a wide range of environmental conditions. It is resistant to shocks and vibrations. It also has excellent thermal conductivity, making it suitable for use in high-temperature applications.

To sum up, the NJ28MA0502F is a reliable and accurate NTC thermistor for temperature sensing applications. It exhibits a large change in electrical resistance as the surrounding temperature changes. It has excellent temperature stability when exposed to a wide range of environmental conditions. It is also small and lightweight, making it ideal for use in temperature measurement. Furthermore, its sensitivity can be adjusted by changing the coefficient of resistance, allowing for precise temperature measurements.
