NTC thermistors, short for Negative Temperature Coefficient thermistors, are a type of semiconductor sensors used to measure temperature. DKF203N3 is a thermistor that utilizes NTC thermistors. This article will discuss DKF203N3\'s application field and working principle.

Application Fields

DKF203N3 thermistors are used in many different types of applications. Some of the most common applications include HVAC systems, automotive systems, medical equipment, and home appliances. The thermistor is used to provide accurate temperature measurements for these applications.

In HVAC systems, the thermistor is used to measure the indoor temperature. This allows the system to properly adjust the temperature setting to ensure the desired temperature is reached. Automotive systems use the thermistor to measure the engine temperature and ensure the engine is operating within the optimum parameters. The thermistor is also used in medical equipment for monitoring body temperature and in home appliances for controlling and monitoring internal heat levels.

Working Principle

DKF203N3 thermistors use an NTC (Negative Temperature Coefficient) semiconductor material. When a current is passed through the material, the material creates a voltage drop proportional to the temperature. The voltage drop is then used to accurately measure the temperature. As the temperature increases, the voltage drop will increase. As the temperature decreases, the voltage drop will decrease.

DKF203N3 thermistors have a resistance range of 30kΩ to 300kΩ. This range allows for the thermistor to accurately measure temperatures from -55°C to +135°C. The thermistor also has a response time of 500 ms, meaning it can quickly adjust to changing temperatures. The thermistor is also highly accurate, with an accuracy of +0.25°C at 25°C.

Conclusion

DKF203N3 is a NTC thermistor used in a variety of applications. It is used for measuring temperature in HVAC systems, automotive systems, medical equipment, and home appliances. DKF203N3 thermistors utilize an NTC semiconductor material that creates a voltage drop proportional to the temperature. The thermistor has a resistance range of 30kΩ to 300kΩ, allowing it to measure temperatures from -55°C to +135°C with an accuracy of +0.25°C at 25°C.
