The Amphenol FCI BERGSTIK 75844-118-16LF is a 16-position, dual-row breakaway header on 0.100" (2.54 mm) pitch. The breakaway design means you snap the strip to exactly the position count your layout needs — 16 positions loaded here, but the same base strip serves other counts off the same reel. Typical use is board-to-board or cable-to-board interconnects where you need a reliable, field-proven pin header at standard 0.100" pitch.
The 0.100" pitch and 0.100" row spacing are the standard 0.025" square pin grid — your board footprint is a 2x8 pattern on 0.100" centers, which matches a huge installed base of IDC sockets and mating receptacles. The 5 A per circuit rating is per contact at the full temperature range; for a 16-position header carrying signal-level current (tens of mA), derating is not a concern, but if you're pushing the full 5 A on several adjacent pins, the temperature rise through the thermoplastic housing (UL94 V-0 rated) is what limits the bundle. The 30 µ" gold GXT plating is the differentiator here — it's rated for hundreds of mating cycles, so this header suits a production harness that gets mated and unmated during test or field service. Tin-plated versions of the same BergStik series are cheaper but wear through faster under repeated mating.
