What this 30-position AMPMODU System 50 receptacle does on the board
Board spacing and stacking height options
The mated stacking heights are 11.94 mm and 13.08 mm, depending on the mating header height. This gives the designer two z-height budgets for the mezzanine gap — confirm the header part number to know which stack height applies. The insulation height of 0.370" (9.40 mm) is the body height above the board; the total stack height includes the mating header's body height above its own board.
