It uses a 0.016\" (0.40mm) pitch in a dual-row layout, with the contacts arranged as outer shroud contacts — the mating interface expects the matching DF37 receptacle with inner contacts. The header sits 0.030\" (0.75mm) above the board surface and achieves a mated stacking height of 0.98mm with its receptacle counterpart, making it suitable for tight z-height budgets in compact portable electronics, camera modules, and handheld devices where every tenth of a millimeter counts. ## Gold Plating and Solder Retention for Reliable Assembly Surface mount termination suits high-speed pick-and-place assembly lines.","metaTitle":"Hirose DF37B-40DP-0.4V(53) Header, 40 Pos, 0.40mm Pitch","metaDescription":"Hirose DF37B-40DP-0.4V(53) header, 40 positions, 0.40mm pitch, 0.75mm above board, gold contacts.
