34-position unshrouded BERGSTIK header
The 77311-122-34LF is the 34-circuit member of Amphenol ICC's BERGSTIK unshrouded pin header line, built for board-to-board stacking at 0.100" (2.54mm) pitch. Rated 3 A per contact with a gold or GXT™ mating finish and a through-hole solder termination, the header runs from -65°C to 125°C in a UL94 V-0 thermoplastic housing.
Unshrouded layout and footprint fit
Single-row unshrouded design with push-pull fastening — the 0.100" (2.54mm) pitch and 0.305" (7.75mm) mating length suit standard pin receptacle strips and IDC sockets on the same grid. The 0.120" (3.05mm) post length fits through-hole boards up to 1/16" nominal thickness; the 0.525" (13.34mm) overall contact length sets the board-to-board standoff when mated.
