Ultra Thin 10K Thermistor - B3950 NTC is designed for temperature sensing where a standard probe is simply too bulky. Its ultra-thin sensing element, noted by the supplier as only 0.2mm wide, makes it well suited for measuring temperature in narrow gaps or when taped onto a flat surface.
This is an NTC thermistor, so its resistance decreases as temperature rises and increases as temperature falls. At 25°C, the rated resistance is 10KΩ with ±1% tolerance, making it a solid choice for accurate measurement and repeatable sensor readings.
For practical use, this thermistor is commonly read with a resistor divider and ADC input on a microcontroller. The supplier also recommends using a lookup table for precise temperature-to-resistance conversion, and notes that guides are available for use with Arduino and CircuitPython.

This thermistor has two terminals and is a passive resistive sensor, so there is no polarity to worry about. It is typically used in a voltage divider circuit and read through an analog input.
Because thermistors are non-linear devices, the most accurate way to convert resistance into temperature is by using the supplier's lookup table or an appropriate thermistor calculation model based on the B3950 characteristic.
Important: avoid exceeding the rated power, as self-heating can affect measurement accuracy. For best results, use low measurement current and mount the sensor so it maintains good thermal contact with the target surface.
This is a 10KΩ NTC thermistor with a B25/50 value of 3950K. As an NTC sensor, its resistance decreases as temperature rises and increases as temperature falls.
Its rated zero-power resistance at 25°C is 10KΩ with ±1% tolerance. The B value is 3950K with ±1% allowable deviation.
The specified operating temperature range is -30°C to +125°C. A temperature-to-resistance lookup table is recommended for accurate conversion across the range.
The sensor body is very slim at 20mm x 4.5mm x 0.5mm, with a total length of 25mm. Its ultra-thin form makes it suitable for measuring temperature in small gaps or when taped to a flat surface.
The supplier notes that this thermistor has usage guidance for both Arduino and CircuitPython. Since it is a standard 10K B3950 NTC thermistor, you would typically read it as a variable resistance and convert the value using the lookup table or thermistor equations.
The specified thermal time coefficient is ≤5 seconds in still air. Its dissipative constant is 0.7 mW/°C in still air, and the rated power is ≤25 mW.
