The 0.40mm pitch packs 44 circuits into a compact footprint, but that tight pitch means the board layout needs careful trace routing — the keep-out zone around the footprint is tight, and routing a full 44 signals between two 0.40mm-spaced pads takes a disciplined fan-out. The shielded construction and gold-plated contacts (1.97µin thickness) point to this being used in high-speed or RF signal paths where crosstalk and corrosion resistance matter. ## SMT Mounting and Solder Retention The solder retention tabs on the shield take the shear load from cable or board handling after reflow — they're not just for alignment. The Tape & Reel packaging (Cut Tape also available) feeds into standard pick-and-place lines.","metaTitle":"Hirose DF40GL-44DS-0.4V(58) Receptacle, 44 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40GL-44DS-0.4V(58) receptacle, 44 positions, 0.40mm pitch, 1.5mm stacking height.
