Thermal Considerations
Module Derating
The derating curves in Figure 16 were determined from
measurements obtained in an experimental apparatus
shown in Figure 19. Note that the module and the
printed-wiring board (PWB) that it is mounted on are
vertically oriented. The passage has a rectangular
cross-section.
