Board-to-board unshrouded header, 30 positions
The 77311-122-30LF is the 30-position member of Amphenol ICC (FCI)'s BergStik unshrouded single-row header line, through-hole soldered with a push-pull fastening interface. Rated 3 A per contact with gold or Gold GXT mating plating over 30.0 µin (0.76 µm) and tin post finish 78.7 µin (2.00 µm); the phosphor bronze contacts and UL94 V-0 thermoplastic insulation support a -65°C to 125°C operating range.
Single-row selection: position count and footprint
The 30-position 77311-122-30LF uses the same 0.100" (2.54 mm) pitch and single-row layout as other BergStik unshrouded headers — the board footprint and mating half are shared across the series, so the position count is the sole selection variable for circuit matching.
