Linear 100K ohm NTC N3950 thermistor 1% (Pack of 5)
These thermistors are small, high-quality, and precision devices with an NTC (Negative Temperature Coefficient) that changes their resistance according to the temperature. They have a consistent R-T (Resistance-Temperature) curve over a wide temperature range, which allows the circuit designer to use the same circuit for different thermistors. They also have an epoxy coating that makes them interchangeable and easy to replace without affecting the calibration of the circuit.

How to Use Linear 100K ohm NTC N3950 thermistor 1%
Mount the thermistor bead close to the measurement point and solder its leads into a voltage-divider network with a fixed reference resistor. Connect the divider output to an ADC input on your controller, then apply the N3950 R-T curve from the datasheet in your code to convert voltage readings into temperature. Secure the epoxy-coated bead against vibration and avoid exceeding its 75 mW power limit to prevent self-heating errors.

Frequently Asked Questions
What is the accurate temperature range for this thermistor?
The Linear N3950 thermistor reliably measures from –80 °C up to 150 °C, maintaining its ±1% resistance tolerance across that span.
How do I wire the 100 kΩ NTC into my microcontroller circuit?
Use it in a voltage-divider configuration with a matching reference resistor (e.g., 100 kΩ) and feed the midpoint voltage into your ADC pin. Then apply the N3950 resistance-to-temperature conversion curve in your firmware.
Can I use this thermistor in high-power heating applications?
This device is rated for a maximum dissipation of 75 mW. It’s ideal for low-power sensing and control—avoid driving excessive current to prevent self-heating and measurement errors.
