Temperature sensors are essential parts of many electronic systems. NTC thermistors are one type of temperature sensor often used in temperature measurement applications. The NJ28QA0503F is one such NTC thermistor designed for use in various applications. This article will discuss the applications and working principle of the NJ28QA0503F.

Uses of the NJ28QA0503F

The NJ28QA0503F is designed for use in a wide range of temperature sensing applications. It can be used for measuring a range of temperatures from -40°C to 150°C. It is suitable for use in automotive, industrial, and consumer applications including air conditioning systems, window units, refrigerators, and dryers. It is also suitable for use in home appliances such as thermoelectric coolers (TECs) and temperature-controlled electrical motors.

Its small size and low cost make it an ideal choice for applications where size and cost are concerns. It is also extremely rugged, with a high level of resistance to shock and vibration. Lastly, the NJ28QA0503F has an extended temperature range, making it suitable for applications in many different environments.

Working Principle of the NJ28QA0503F

The NJ28QA0503F is a type of negative temperature coefficient (NTC) thermistor. A thermistor is a temperature-sensitive resistor whose resistance changes with temperature changes. It works on the principle that when the temperature of the thermistor increases, its resistance decreases, and vice versa. The NJ28QA0503F has a resistance of 25KΩ at 25°C that drops to 4KΩ at 150°C.

This resistance variation can be exploited to determine changes in temperature. To do this, the thermistor is connected in a voltage divider circuit with another resistor. By measuring the voltage drop across the thermistor, it is possible to determine the temperature of the thermistor and thus the ambient temperature. This is done by measuring the voltage drop across the thermistor and then using an appropriate equation to calculate the temperature.

Conclusion

The NJ28QA0503F is an NTC thermistor designed for use in temperature sensing applications. It is suitable for use in automotive, industrial, and consumer applications due to its small size, low cost, and extended temperature range. It works on the principle that when the temperature of the thermistor increases, its resistance decreases and it can be connected in a voltage divider circuit to measure the temperature.
