BERGSTIK 40-position breakaway header
The 77317-103-40LF is the 40-circuit member of Amphenol ICC's BERGSTIK unshrouded breakaway header line, configured as a dual-row through-hole right-angle board-to-board interconnect. Mating contacts carry a gold GXT finish rated 3 A per contact; the post side is tin-plated for solderability. The 0.100" (2.54mm) pitch and row spacing match the standard BERGSTIK footprint.
Position count and series fit
The 40-position 77317-103-40LF sits at the upper end of the BERGSTIK dual-row right-angle range — the pitch, row spacing, and unshrouded profile are shared across the series, so the position count alone determines the board footprint length.
