‡ The ratio, at a specified ambient temperature, of the change in the power dissipation of the sensor to the resultant 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.
‡‡‡ Test fixture fitted with 3/8"-18 NPSF Internal Threads.

Important: The values above are for the unloaded thermistor, as shipped from Packard Electric, and does not reflect the effects of application system errors and aging.
*Note: Please contact PE Engineering for the resistance vs. temperature curve for your temperature sensor application. Due to self-heating effects of the thermistor, the resistance is dependent on the application.
Since thermistors are "continuous function devices", resistance vs. temperature data is available for numbers beyond those specified above.
