Product details

Board-to-Board Mezzanine Connector for 3mm Stack Heights

The Hirose DF12(3.0)-40DS-0.5V(86) is a 40-position receptacle with center strip contacts from the DF12 series, designed for board-to-board mezzanine stacking at a fixed 3mm mated height.

What the 3mm Stack Height Means for Your Board Layout

The 0.50mm pitch keeps the routing density high — traces between pads need careful neck-down, and a via-in-pad or microvia strategy is typical for breakout on inner layers. The board guide features help align the two halves during hand or automated assembly, reducing shear stress on the SMT solder joints.
