A 36-Position Mezzanine Header for Tight Board Stacks
The Hirose DF12D(4.0)-36DP-0.5V(81) is a 36-position SMT header from the DF12 series, designed for board-to-board mezzanine stacking at a tight 4mm mated height. Outer shroud contacts provide alignment during mating and protect the terminals from side-load damage, which matters in assemblies where the boards are stacked without a separate guide frame.
What the Stacking Height and Pitch Mean for Your Board Layout
The 0.50mm pitch forces the trace fan-out to use fine-line routing or via-in-pad on the inner rows; expect to drop to micro-vias if routing all 36 signals out of a single layer.
