It is designed for parallel-stacking mezzanine applications where the mated pair occupies a 2 mm stack height. The gold-plated contacts with 4.00 µin thickness provide corrosion resistance suitable for moderate mating-cycle duty in consumer and industrial environments. ## Board Layout and Assembly Considerations The 0.50 mm pitch requires careful trace routing — expect micro-via fanout or blind vias for the inner rows on a standard PCB. The 1.65 mm height above board sets the z-axis clearance for the mezzanine pair; confirm the enclosure gap accommodates the 2 mm mated stack height plus any component keep-out on the opposing board. Surface-mount termination with solder retention tabs provides mechanical hold during reflow — no through-hole anchors. The ground plate should be connected to the PCB ground plane with multiple vias to maximize its shielding and return-current benefit.","metaTitle":"Hirose FX11LA-100S/10-SV(71) Receptacle, 100 Pos","metaDescription":"Hirose FX11LA-100S/10-SV(71) receptacle, 100 positions, 0.50mm pitch, 1.65mm stack height, gold contacts.
