BERGSTIK unshrouded header, 22-circuit right-angle
The 54772-101-22LF is the 22-circuit member of Amphenol ICC (FCI)'s BERGSTIK unshrouded pin header line, a board-to-board interconnect in a through-hole right-angle orientation. Contacts are phosphor bronze with 30.0µin (0.76µm) gold GXT on the mating surface and 78.7µin (2.00µm) tin on the post; the thermoplastic housing carries a UL94 V-0 flammability rating.
Pitch and footprint — dual-row 0.100" grid
Mating pitch and row spacing are both 0.100" (2.54mm), placing the 54772-101-22LF on the industry-standard 0.100" x 0.100" grid — the same footprint shared across the BERGSTIK dual-row line, so the board layout carries over when the position count changes.
