The Amphenol 68031-103HLF is a 3-position, single-row BERGSTIK® II unshrouded male pin header on the standard 0.100" (2.54 mm) pitch. The through-hole solder tails lock the header into the board mechanically before reflow or wave solder. The gold thickness is the real story here — it buys you repeated mating cycles and corrosion resistance over a tin-plated part, which matters if this header lives in a field-serviceable assembly or a mildly corrosive environment.
Where it fits
Three positions match a 3-circuit BOM line.
