The FCI BERGSTIK® 75160-118-20LF is an unshrouded male pin header, 20 positions in a single row on 0.100" (2.54 mm) pitch — a standard footprint that matches legacy perf-board and breadboard layouts as well as production PCB patterns. It uses through-hole solder termination with a 0.120" (3.05 mm) post length, and the 0.225" (5.72 mm) mating pin length gives enough reach to engage standard female socket strips or IDC receptacles. The GXT™ alloy itself is a hardened gold formulation that extends wear life beyond what the gold thickness alone would suggest.
Where it fits and what it mates with
The single-row 20-position layout is common for I/O breakouts, programming headers, and test points. All 20 positions are loaded — no option for selective population on this variant.
