It uses a 0.100\" (2.54mm) square-pin grid on both pitch and row spacing, making it a standard footprint for prototyping and production. The mating contacts are finished with 30.0µin (0.76µm) of Gold, GXT™ — a hard gold alloy that holds up through repeated mating cycles better than standard soft gold, which matters if this header sees field-service reconnects or lives in a corrosive environment. The housing is molded from UL94 V-0 rated thermoplastic in black, with an operating temperature range of -65°C to 130°C that covers automotive underhood and industrial cabinet environments. The 0.225\" (5.72mm) mating pin length ensures reliable contact wipe with industry-standard receptacles. The 0.100\" row spacing matches the pitch, so the footprint is a simple 2-row grid of 0.040\" square holes on 2.54mm centers — a layout that routes easily on two-layer boards. The 0.445\" (11.30mm) overall contact length keeps the header low-profile enough for card-edge applications where the mating connector sits close to the board.","metaTitle":"FCI 75844-156-34LF BERGSTIK Header, 34 Pos, 2.54mm Pitch","metaDescription":"FCI 75844-156-34LF BERGSTIK 2-row unshrouded through-hole header, 34 positions at 0.100\" pitch, rated 5A, 30µin GXT gold.
