The Hirose FX11A-100P/10-SV0.5(71) is a 100-position, 2-row header from the FX11 series, using outer shroud contacts and a 0.50 mm pitch. It is a board-to-board mezzanine connector designed for parallel PCB stacking at a fixed 3 mm mated height. The header carries gold-plated contacts with a 4.00 µin flash, and includes a board guide, ground plate, and solder retention features to assist assembly and signal integrity.
Stacking Height and Board Fit
The header itself stands 2.63 mm above the board surface.
Assembly and Retention Details
The ground plate provides a low-inductance return path, which is useful for high-speed signals where ground bounce needs to be controlled.
