NTC thermistors are a type of temperature sensor that can be used to measure temperature under varying environments. The NTC0805J680R is a thermistor composed of a metal oxide film that is sandwiched between two electrodes. Its resistance changes with temperature, making it an ideal choice for temperature sensing applications. This article will take a look at the application field and working principle of the NTC0805J680R.

Application Field of NTC0805J680R

The NTC0805J680R is designed for use in temperature sensing and temperature control applications. Its main applications include:

• Temperature measurement.
• Temperature control systems.
• HVAC systems
• Medical equipment
• Air conditioning systems
• Industrial process control

The thermistor is highly accurate and has a wide temperature sensing range extending from -60°C to +150°C. It has a low thermal time constant allowing for fast temperature changes to be detected and it is also shock and vibration-resistant.

Working Principle of NTC0805J680R

The NTC0805J680R thermistor works by changing its resistance in relation to the temperature. This is known as the temperature coefficient of resistance (TCR). As the temperature increases, the resistance of the thermistor decreases linearly, meaning it can be used to accurately measure temperature.

The thermistor is composed of a sintered metal oxide film between two electrodes. When this film is exposed to a change in temperature, the resistance changes and a small electrical current flows through the circuit. This current is then measured by a connected temperature controller that converts the current to a temperature reading.

The NTC0805J680R comes with a tolerance of +- 1%. This allows it to provide accurate temperature readings, making it an ideal choice for use in temperature sensing and control applications.

Conclusion

The NTC0805J680R is an accurate and reliable thermistor designed for use in temperature sensing and control applications. Its low thermal time constant allows for fast temperature changes to be detected and it is also shock and vibration-resistant. Its wide temperature range and accuracy make it an ideal choice for use in HVAC systems, medical equipment, air conditioning systems, and industrial process control.
