0.40mm Pitch Mezzanine Header for Tight Stack Heights
The Hirose DF37B-30DP-0.4V(51) is a 30-position header from the DF37 series, designed for board-to-board mezzanine connections where vertical space is at a premium. With a 0.016" (0.40mm) pitch and a mated stacking height of 0.98mm, this connector suits compact handheld or portable electronics that need a low-profile signal interconnect.
The 2-row, 30-position layout requires a precise footprint — the 0.40mm pitch demands careful PCB routing and a solder paste stencil matched to the land pattern.
