About this product
A 10kΩ negative temperature coefficient (NTC) thermistor with a B-value of 3950, in a 2 mm diameter, 30 mm long lead-type body. Its resistance falls as temperature rises, so it suits temperature measurement, compensation and control circuits read through a voltage divider and an analog input.

How do I read temperature with this thermistor on an Arduino or ESP32?
Connect a fixed 10kΩ resistor between the supply and the analog pin, and the thermistor between the pin and GND. Then calculate R = 10k × ADC / (ADC_max − ADC) and convert R to temperature with the B-parameter equation using B = 3950 and T0 = 298.15 K at 25 °C, or with a lookup table.
What does the 3950 in the part number mean?
3950 is the B-value in kelvin, which describes how strongly the resistance changes with temperature. It is used in the Beta equation R(T) = R25 × exp(B × (1/T − 1/T25)), where T and T25 are absolute temperatures in kelvin.
