The Amphenol FCI 10146065-113Q0LF is a 164-position PCI Express female connector on a 0.039" (1.00mm) pitch, dual-readout, surface-mount design. It accepts a standard 0.062" (1.57mm) thick PCI Express card and terminates via solder to the PCB.
Position Count and Pitch — The BOM Match
At 164 positions, this connector matches the full x16 PCI Express lane count — one position per lane pair plus management sideband. The 1.00mm pitch keeps the overall card-edge footprint compact while still allowing two rows of contacts for the dual-readout architecture. Compared to the 10139595-110T0LF which carries 280 positions for a different form factor, the 164-position body here is the standard x16 slot length. The sibling 10146070-113Y0LF shares the same 164 positions, 1.00mm pitch, and 30.0µin gold but adds a locking ramp and board guide features — if your design needs positive retention of the card edge, that variant is the one to spec.
