Board-to-board unshrouded pin strip
The 77311-822-25LF is the 25-position member of Amphenol ICC (FCI)'s BERGSTIK® unshrouded header line, designed for board-to-board stacking with a push-pull fastening system. Rated 3A per contact with a -65°C~125°C operating range, the header carries gold or GXT™ plating on the mating surface and tin on the solder posts, with a UL94 V-0 thermoplastic insulator.
Single-row footprint and routing
The single-row 0.100" (2.54mm) pitch leaves a narrow board footprint — the 25 through-hole posts occupy a single row of plated holes, freeing adjacent routing channels for signal traces on the same layer.
