The 3DA100J thermistor has become a preferred choice for medical equipment due to its accuracy and stability. Its small size and wide temperature range also make it ideal for use in space applications where size and weight are of great concern.

Advantages

The 3DA100J NTC thermistor offers superior accuracy and stability in temperature measurements. Its small size and wide temperature range make it a perfect choice for various applications. In addition, it has a high resistance ratio, an excellent coefficient of temperature, and a low temperature coefficient of resistance. All these features further add to its effectiveness, making it a safe and secure solution for any temperature measurement needs.

Working Principle

The 3DA100J NTC thermistor works on the principle of resistance variation with temperature change. It uses a ceramic body, composed of a semiconductor material, with a negatively charged surface. As the temperature rises, the body expands and the molecules on its surface become increasingly mobile. As they move closer to the positively charged electrode, they create a current that causes the resistance of the sensor to decrease. Conversely, as the temperature drops, the molecules move farther away from the positive electrode, which causes the resistance of the sensor to increase. This change in resistance is measured and used to calculate the temperature of the sensor\'s surrounding environment.

Conclusion

The 3DA100J thermistor is an invaluable tool for temperature measurement in a variety of applications. Its accuracy and stability, small size, wide temperature range, and excellent resistance ratio make it the perfect choice for reliable temperature measurements. With its range of features and capabilities, it is no wonder that the 3DA100J thermistor is preferred by many industries for their temperature measurement needs.
