NTC 10K Thermistor Temperature Sensor

NTC 10KΩ B3950 Negative Temperature Coefficient Thermistor

This 10kΩ NTC thermistor exhibits a steep, highly predictable decrease in resistance as temperature rises. Encapsulated in protective epoxy, it is the standard temperature sensing element for 3D printer heated beds, battery management thermal cutoffs, and smart HVAC thermostats.
