The FCI 75160-148-36LF is a 36-circuit unshrouded male header from the BERGSTIK series, on a 0.100" (2.54 mm) pitch. It is a through-hole, single-row board-to-board interconnect with push-pull mating. Rated 5 A per circuit at 110 V, with an operating temperature range of -65°C to 130°C and a UL94 V-0 thermoplastic housing. This is a workhorse general-purpose header for prototyping, production board stacking, and signal distribution where a reliable, unshrouded pin header is called for.
For a 36-position board-to-board interconnect in a system that sees field service or rework, that plating grade buys you a lot of margin before you start seeing intermittent opens.
The 0.100" pitch and 0.230" mating pin length give a standard footprint that fits a wide range of mating receptacles — the matching BERGSTIK receptacle or any 0.100" pitch IDC socket with a 0.230" insertion depth. The 0.095" solder post length is on the short side, so check your board thickness before committing: it works with standard 1.6 mm boards but may not protrude enough for thick backplanes or hand-soldering through plated-through holes with a heavy ground plane.
