The Amphenol FCI 67998-122HLF is a dual-row unshrouded header from the BERGSTIK II series, packing 22 positions on the standard 0.100 inch (2.54 mm) pitch grid. The 0.100 inch (2.54 mm) row spacing gives a compact 11-pin-per-side layout that fits breadboard and standard perfboard patterns without a custom footprint.
The overall contact length is 0.525" (13.34 mm), with a mating length of 0.318" (8.08 mm) and a post length of 0.107" (2.71 mm) — the short post suits thinner PCBs or shallow solder wells. Phosphor bronze contacts and a UL94 V-0 black housing round out the build. All 22 positions are loaded, so the pinout is full and symmetrical across both rows.
