Through-hole right-angle 40-position breakaway header
The 77317-403-40LF is the 40-circuit member of the Amphenol ICC BERGSTIK® breakaway header line, a dual-row unshrouded board-to-board interconnect on 0.100" pitch. Rated 3 A per contact with tin-plated mating surfaces, the header mounts through-hole right-angle and carries UL94 V-0 thermoplastic insulation.
Position count and footprint across the series
The 40-position 77317-403-40LF sits at the upper end of the BERGSTIK® dual-row right-angle range — the 0.100" pitch and 0.100" row spacing are shared across the series, so the board footprint scales linearly with position count.
