The NTC 3950 100K ohm thermistor is a Negative Temperature Coefficient (NTC) resistor, meaning its resistance decreases as the temperature increases. The "100K ohm" refers to the sensor's 100 kΩ resistance at 25°C, while "3950" represents the B-value (temperature coefficient), which defines the response to temperature changes.
The NTC 3950 100K thermistor is a popular choice for temperature regulation of heated beds in 3D printers. Due to its design, it can also be used attached to stepper motors to monitor their temperature.
