Curve Tracking and Point Matched

NTC Thermistors
tolerance based on the temperature coefficient at each
temperature point within the specified range. Standard
temperature tolerance and ranges are listed below, along with
the available styles and resistances.
Curve Tracking Thermistors are “curve matched” to desired
temperature tolerances over selected temperature ranges.
They allow component standardization and can reduce cost
associated with assembly because they are curve tracking to
within the tolerance and temperature range specified without
re-calibration. They are ideally suited for use in
To specify, add the appropriate suffix from the following table
to the part number.
microcomputer measurement and control circuits. The
temperature tolerance corresponds to a resistance
Example: 1M1002-B3 = Curve 1, 10 kilohms at + 25°C,
curve tracking to ± 0.5°C from 0° to + 70°C.

Point Matched Thermistors are available for applications
which require a specific resistance value matched to a
specific temperature point. (Example: 10,000 ohms ± 2%
at + 80°C.) They are useful for applications which require
temperature monitoring at a critical temperature point
to control, measure or shutdown. Consult factory with
requirements.
NOTE: All thermistors listed in this catalog are point matched
thermistors at + 25°C.
