TOLERANCES AVAILABLE FOR TYPE M, C AND T THERMISTORS
DESCRIPTION OF THERMISTOR TOLERANCES
The many applications of thermistors have mandated the need for two basic tolerance schemes for these products - Curve
Tracking and Point Match Thermistors. An example of the resistance tolerance at various temperatures for the two different
tolerancing methods is described in the following graph:

CURVE TRACKING TOLERANCE
Thermistors are calibrated at the high temperature of the curve track range and then final tested at the low temperature of the
curve track range. This ensures that the thermistor will meet the specified temperature accuracy at every temperature within
the desired temperature range. Several temperature ranges are available and the accuracy of the thermistor may be ± 0.2 °C,
± 0.5 °C, and ± 1.0 °C. The Curve Tracking temperature ranges and their code designators are shown in Figure 1 and Table 1.
To specify, add the appropriate suffix from the following table to the part number.
Example: 1M1002-B3 = Curve 1, 10 kilohms at + 25 °C, curve tracking to ± 0.5 °C from 0 °C to + 70 °C
