TIME
* The ratio, at a specified ambient temperature, of the change in the power dissipation of the sensor to the
resulant temperature change of the thermistor. Test medium: silicone oil
** The time required for the sensor to achieve 63.2% of its steady state value when subjected to a step change
in ambient temperature [Tc=(Tf-Ti)*63.2%+Ti]. Test medium: silicone oil.

Note: Temperature Sensor Calibration Resistance Guaranteed by 100% Automated Calibration Certification.
The values above are for the unloaded thermistor, as shipped from Delphi Packard Electric, and
does not reflect the effects of application system errors and aging.
Notes:
Please contact Delphi Packard Engineering for the resistance vs temperature curve for your
temperature sensor application. Due to self-heating effects of the thermistor, the resistance is dependant upon
the application.
Since thermistors are "continuous function devices", resistance vs temperature data is available for
numbers beyond those specified above.
