Product details

Dual-row 56-circuit breakaway header

The 77313-424-56LF is the 56-circuit member of Amphenol ICC's BERGSTIK® breakaway header line, a board-to-board or cable interconnect in a dual-row 0.100" pitch layout. Rated 3 A per contact with tin-plated mating surfaces, the header operates from -65°C to 130°C and carries a UL94 V-0 thermoplastic housing.

Unshrouded through-hole fit

Unshrouded and push-pull fastening — the 0.100" insulation height and 0.266" mating pin length leave clearance for board-edge placement without a shroud wall. Through-hole solder termination with 0.114" post length suits wave-solder assembly; the 78.7µin tin post finish matches the board pad finish without a mixed-plating interface.

Frequently asked questions
