The Hirose DF12A(3.0)32DS0.5V80 is a 32-position receptacle from the DF12 series of board-to-board mezzanine connectors. It uses a 0.50mm pitch, arranges contacts in 2 rows, and is designed for a fixed mated stacking height of 3mm. The surface-mount termination and gold-plated center strip contacts suit it for dense, low-profile interconnects inside portable electronics, handheld devices, and compact embedded systems where board spacing is tight.
Key Ratings and Fit
The 0.50mm pitch and 32 positions define the board footprint — each contact sits on a tight grid that demands careful routing clearance on inner layers. The 3mm mated stacking height sets the z-axis budget between the two PCBs; the connector itself stands 2.20mm above the board. Gold contact finish provides corrosion resistance suitable for the moderate mating-cycle duty of a mezzanine interconnect inside an assembled product.
