Board-Stacking Connector for Dense Mezzanine Designs
The Hirose DF12(3.0)-80DS-0.5V(86) is an 80-position receptacle from the DF12 series, designed for board-to-board mezzanine stacking at a 3mm mated height. With a 0.50mm pitch and 2 rows of gold-plated center strip contacts, it packs high signal density into a compact footprint for space-constrained PCBs.
The gold contact finish at 8.00µin handles moderate mating cycles common in production test or field-swappable modules; for high-cycle applications (500+ mates), you'd typically spec thicker gold, but this part's lifecycle status makes that a moot point for new designs.
