The 0.50mm pitch keeps the footprint compact — you're routing 40 signals through a board area that a 2.54mm pitch header would need three times the space for. This is a mezzanine interconnect for tight z-height budgets — think handheld devices, camera modules, or any assembly where the board gap is exactly 3mm and you need a reliable, production-ready SMT joint. ## Sizing the Board Layout Around the 0.50mm Pitch At 0.50mm pitch, the trace escape from the inner rows is the main layout constraint. You'll need at least a two-layer board with via-in-pad or microvias to route all 40 signals out cleanly — a single-layer fanout at this density is tight. The header sits 0.091\" (2.30mm) above the board, so the total stack height with the mating receptacle is 3mm. That's a fixed dimension — no adjustment for board thickness variation. The solder retention features (small tabs on the body) add a mechanical anchor during reflow; they don't carry current but they prevent tombstoning on a dense board.","metaTitle":"Hirose DF12NB(3.0)-40DP-0.5V(51), 40-Position 0.50mm Header","metaDescription":"Hirose DF12NB(3.0)-40DP-0.5V(51) header, 40 positions, 0.50mm pitch, 3mm stacking height.
