The rise in temperature between the operating temperature and the case. If you enter a value for this parameter, this value is added to the operating temperature. If you prefer, you can directly enter the value for the case temperature for Case Temp Override. However, when you enter an override value, any changes to the subassembly temperature or to factors contributing to the temperature rise are not taken into account.

Generally this field is left at #.# so that the case temperature is calculated. If you enter a value for this parameter, this value is used in place of a calculated temperature rise. (Perhaps you want to use the temperature value obtained from an infrared scanner or a thermal engineer.) Using this method, changes to the subassembly temperature or to factors contributing to the temperature rise are not taken into account.

The maximum junction temperature, which is normally available in the manufacturer's databook. The part is flagged as overstressed if the sum of the temperature rise and subassembly temperature is greater than the maximum junction temperature. This field is shown only for certain types of capacitors and resistors.
