MF51E
High
Precision NTC Thermistors for Extremely Accurate
Temperature Measurement
The
MF51E NTC Thermistors were specially designed for
use in electronic thermometers which require better
than average accuracy. The extremely small size
allows the thermistor to respond very quickly to
tiny changes in temperature. The MF51E can be supplied
un-calibrated with standard tolerances or calibrated
and grouped according to R at 37°C±0.01%
for extreme interchangeability so as to eliminate
the need for other calibrations.
