Description
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.
Application
• Electronic Thermometers
• Medical Equipment and Patient Monitoring
