Module Derating
The derating curves in Figure 22 were derived by mea-
surements obtained in an experimental apparatus
shown in Figure 30. Note that the module and the
printed-wiring board (PWB) that it is mounted on are
both vertically oriented. The passage has a rectangular
cross section.
Note: Dimensions are in millimeters and (inches).
