The overall contact length of 0.410\" (10.41 mm) breaks down into a 0.190\" (4.83 mm) mating length and a 0.120\" (3.05 mm) solder post, which means the board-to-board stack height is set by the receptacle's mating depth plus the header's own height above the board. ## Plating and current","metaTitle":"Amphenol FCI 79425-426HLF BERGSTIK II Header, 26 Pos","metaDescription":"Amphenol FCI BERGSTIK II unshrouded header, 26 positions dual-row, 0.100\" pitch, 5 A, 110 V, tin-plated, UL94 V-0.
