100K NTC Thermistor B3950 with Glass Encapsulation for Temperature Measurement

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The 100K NTC thermistor with B3950 is a temperature sensitive component designed for accurate temperature measurement. The thermistor has a nominal resistance of 100 kOhm at 25 degrees C and its resistance decreases as the temperature increases. The B3950 value specifies the thermistor Beta value and is used together with the reference resistance to calculate the temperature from the measured resistance.

The glass encapsulation provides good protection for the thermistor element and makes the sensor suitable for applications where temperature resistance, moisture resistance and long service life are important. The specified operating temperature range is from -40 to +300 degrees C, providing a wide margin for measurements in applications such as -20 to +40 degrees C.

The thermistor can easily be used as a voltage divider together with a microcontroller such as Arduino or other equipment with an analog input. For temperature measurement within the -20 to +40 degrees C range, a divider resistor of approximately 100 kOhm is a suitable choice. At 25 degrees C the NTC resistance is approximately 100 kOhm, providing a good distribution of the measurement range.

The thermistor is suitable for temperature monitoring, electronic measuring instruments, control systems, sensors and custom electronics projects. The glass encapsulation also provides fast temperature response due to the small size of the thermistor.
