The connector is designed for parallel board stacking at a fixed 3mm mated height, with a 2.30mm profile above the board surface. Surface-mount termination suits automated pick-and-place and reflow soldering lines. Gold-plated contacts (8.00µin) provide stable contact resistance for signal-level currents through repeated mating cycles. ## 3mm Stack Height — The Dimension That Decides the Fit The mated stacking height is 3mm — this is the distance between the two parallel PCBs when the header is mated with its matching receptacle.","metaTitle":"Hirose DF12NC(3.0)-40DP-0.5V(51) Header, 40 Pos","metaDescription":"Hirose DF12 series header, 40 positions, 0.50mm pitch, 3mm stack height, SMT, gold contacts, RoHS.
