The 0.100\" (2.54 mm) pitch is the classic square-pin grid — every board house knows the drill pattern, and the 0.025\" square pins drop into standard stamped receptacles. The 0.730\" (18.54 mm) overall contact length includes a 0.430\" (10.92 mm) mating tail and a 0.200\" (5.08 mm) solder post, which sets the board-to-board stack height when mated with a standard receptacle.","metaTitle":"FCI BERGSTIK II 79821-128HLF Header, 28 Pos, 0.100\" Pitch","metaDescription":"FCI BERGSTIK® II unshrouded header, 28 positions, dual row, 0.100\" pitch, 5 A, 30 µ\" gold plating.
