NTC Thermistors, or Negative Temperature Coefficient Thermistors, are devices that change resistance in response to changes in temperature. With negative coefficient parts, their resistance decreases as their temperature increases. They are typically defined with variables such as the parts base resistance value at a set temperature, usually 25°C, and B values, the performance curve of temperature vs. resistance calibrated between two fixed points.
