30-position unshrouded header, 2.54 mm pitch
The 77311-127-30LF is the 30-position member of Amphenol ICC (FCI)'s BERGSTIK unshrouded header line, a single-row board-to-board interconnect on 0.100" (2.54mm) pitch. Rated 3 A per contact with gold or GXT mating finish (30.0µin thickness) and tin-plated posts, the header operates from -65°C to 125°C and carries a UL94 V-0 thermoplastic insulator.
Pitch, footprint, and routing density
The 0.100" (2.54mm) pitch sets the board footprint and routing density — the single row leaves a narrow keep-out zone, and the 0.260" (6.60mm) mating length provides a standard through-hole engagement depth. The unshrouded push-pull fastening means the header mates with any standard 0.100" pitch receptacle; the 0.105" (2.67mm) post length suits typical 1.6 mm PCB thickness.
