40-position breakaway header, 0.100" pitch
The 77313-120-40LF is the 40-circuit member of Amphenol ICC's BERGSTIK breakaway header line, a dual-row unshrouded pin header on 0.100" (2.54mm) pitch with a push-pull fastening interface. Rated 3A per contact with gold or GXT mating finish (30.0µin/0.76µm thick) and tin-plated posts, the header operates from -65°C to 130°C and carries a UL94 V-0 thermoplastic housing.
BERGSTIK breakaway series — position count ladder
Within the BERGSTIK 77313 series the 40-position 77313-120-40LF occupies the middle of the dual-row range — the pitch, row spacing, and unshrouded push-pull design are shared across the series, so the position count alone determines the board footprint length.
