The TE Connectivity 5145165-4 is a 184-position female card edge connector from the Standard Edge.050 series, designed to mate with a PCI 3.3V 64-bit add-in card. The 0.050" (1.27 mm) pitch and dual-row readout match the standard PCI edge finger layout, while the 3.3V keying prevents insertion into a 5V slot. The natural thermoplastic housing includes a board guide feature to align the card during insertion, reducing stress on the 184 solder tails.
Contact Finish and Termination Details
That gold thickness supports repeated card insertions — think test fixtures or production burn-in racks where the connector sees hundreds of cycles. The solder tails are staggered in a through-hole pattern, which spreads the insertion force across the wave solder process and helps with alignment on a dense 184-position footprint.
Board Fit and Card Thickness
If your PCB is thicker or thinner than 0.062", the contact normal force changes — stick with the spec to maintain reliable connection over temperature cycles.
