An NTC thermistor (Negative Temperature Coefficient thermistor) is a type of temperature-sensitive resistor whose resistance decreases as its temperature increases. It is made from semiconductor materials, typically metal oxides like manganese, nickel, or cobalt, sintered into a ceramic form.
-Resistance drops as temperature rises (unlike PTC thermistors, which have a positive coefficient).
-Highly nonlinear response but very sensitive to small temperature changes.
-More responsive than RTDs (Resistance Temperature Detectors) or thermocouples in certain ranges.
-Best suited for narrow to moderate temperature ranges (typically -50°C to 150°C, though some go higher).
-Small size, fast response, and low cost.
-High sensitivity in its operating range.
-Nonlinearity requires calibration or lookup tables.
-Limited temperature range compared to RTDs/thermocouples.
-Self-heating can affect accuracy if not properly designed.
