HiTCE: Green ceramic is thermally matched to FR4 circuit board.
The aluminum lid is electrically connected to the grounded substrate of the C-5 NP.
Neither the lid nor any heat sink connected to the lid should be part of a current-carrying
path. It is acceptable, however, to connect the lid or heatsink to ground if necessary
(through the standoff screws for the heat sink).
