28-Position Dual-Row Unshrouded Header on 0.100" Pitch
The 71277-228HLF: Surface-mount solder termination means this header reflows with the board in a single pass — no secondary soldering step.
Gold Plating and Mating Cycle Life
The post (solder tail) is tin-plated, which is standard for SMT reflow compatibility — the gold-on-tin interface at the solder joint is avoided by the selective plating process.
Unshrouded design means the mating receptacle must provide its own alignment — the header itself offers no shroud to guide the plug. Row spacing is 0.100" (2.54 mm), matching the pitch.
Packaged in tray — typical for manual or pick-and-place assembly. The base product number 71277 covers the series variant family; this specific order code carries the full 28-position load.
