It uses a 0.50mm pitch and a 3mm mated stacking height, making it suited for compact, parallel-PCB assemblies where vertical clearance is tight. The connector is a surface-mount, dual-row receptacle with center strip contacts and gold plating at 8.00µin thickness on the mating interface. ## 40 vs 50 Positions — Same Footprint, Different Density The DF12NC(3.0)-40DS-0.5V(51) shares the same 0.50mm pitch, 3mm stack height, and gold plating as the 50-position sibling DF12NC(3.0)-50DS-0.5V(51). If your BOM calls for 40 signal lines, this is the exact match; the 50-position version adds 10 extra contacts that would require a different PCB layout. ## SMT Termination and Tape & Reel Packaging This receptacle uses surface-mount termination, which means it reflows directly onto PCB pads — no through-hole soldering required. The Tape & Reel packaging (with a Cut Tape option) feeds standard pick-and-place lines without a tooling change. The 0.50mm pitch demands a fine-pitch placement head and careful solder paste stencil design to avoid bridging between adjacent pads.","metaTitle":"Hirose DF12NC(3.0)-40DS-0.5V(51) Receptacle, 40 Pos, 0.50mm","metaDescription":"Hirose DF12NC(3.0)-40DS-0.5V(51) 40-position receptacle, 0.50mm pitch, 3mm stack height, SMT, gold contacts.
