The B3950 10K NTC Thermistor Temperature Sensor utilizes a negative temperature coefficient (NTC) element where resistance decreases predictably as temperature increases. The sensing element is housed within a robust 5mm diameter by 20mm long stainless steel sheath, providing mechanical protection and environmental sealing for applications involving moisture or condensation. The integrated 0.5-meter cable with XH2.54 connector offers a convenient interface for direct connection to custom breakout boards or data acquisition systems.
Accurate temperature reading requires processing the thermistor’s non-linear resistance curve, typically achieved via a voltage divider circuit and microcontroller ADC. The sensor’s low thermal mass and typical dissipation constant of 5mW/°C ensure minimal self-heating and fast response times. With an insulation resistance greater than 100 MΩ, it is suitable for integration into 3D printer hotends, HVAC monitoring systems, aquarium controllers, and other precision thermal management setups.
