The 0.016\" (0.40mm) pitch packs 48 circuits into a compact footprint, and the shielded outer shroud contacts help contain EMI in tight digital modules — think camera modules, display interconnects, or compact compute stacks. Gold contact finish is standard across the DF40GB variants, giving a corrosion-resistant mating surface suited for repeated assembly in consumer or portable equipment. ## Mated Stack Heights and Board Fit This plug sits 0.045\" (1.14mm) above the board after reflow. The datasheet lists mated stacking heights of 1.5mm and 3mm — the actual height depends on which matching DF40 receptacle you pair it with. For a 1.5mm total stack, the board-to-board gap is tight; verify the keep-out zone on the opposing board clears the tallest component. The 0.40mm pitch means trace routing between pads is possible with standard PCB fab capabilities, but the fan-out vias need careful placement to avoid shorting between adjacent pads.","metaTitle":"Hirose DF40GB-48DP-0.4V(58) Plug, 48 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40 series plug, 48 positions, 0.016\" (0.40mm) pitch, gold contacts, shielded SMT.
