Module Derating
The derating curves in Figures 43 through 45 were
determined by measurements obtained in an experi-
mental apparatus shown in Figure 61. 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).
Layout Considerations
Copper paths must not be routed beneath the power
module standoffs.
