Need to measure something with a very slim sensor? This precision 10K thermistor is an inexpensive way to measure temperature in a small gap, or taped to a flat surface, it's only 0.2mm wide!

The resistance in 25°C is 10K (+- 1%). The resistance goes down as it gets warmer and goes up as it gets cooler. For specific temperature-to-resistance, check the lookup table.

We have a great detailed tutorial on how thermistors work and how to use this one with both Arduino & CircuitPython!

We also carry an epoxy-coated precision 1% 10K thermistor.
