The product will be reserved for you when you complete your order. The resistance of the thermistor will change according to temperature, and should track with the following table. In the typical control range (0°C to 40°C), 10K thermistors offer good sensitivity to changes in temperature, and this is the range in which most 10K thermistors are typically used. Thermistors are manufactured to follow a specific curve with a high degree of accuracy.
