It's designed for board-to-board mezzanine stacking where the mated height is 0.98mm — tight for compact handheld or module-to-motherboard interconnects. Gold flash plating (2.00µin) on the contacts handles moderate mating cycles typical of internal device connections. The 0.40mm pitch drives the board footprint — trace escape between pads needs a fine-line PCB fab capable of 0.20mm or tighter trace/space. The 0.75mm height above board is the header's own standoff from its mounting surface. ## Plating Grade and Duty Cycle If your application needs higher cycle life or sees corrosive atmospheres, the sibling DF37B-20DP-0.4V(75) carries 4.00µin gold, which doubles the wear layer at the same pitch, position count, and stack height. That extra thickness buys you more reconnect margin without changing the footprint.","metaTitle":"Hirose DF37B-20DP-0.4V(53) Header, 20 Pos, 0.40mm Pitch","metaDescription":"Hirose DF37B-20DP-0.4V(53) 20-position header, 0.40mm pitch, 0.75mm board height, gold contacts.
