The FCI 78511-108HLF is an 8-position, single-row BERGSTIK® II unshrouded header on a 0.100" (2.54mm) pitch. This is a through-hole, vertical-mount male pin header with square pins, rated for 5A per contact at 110V. The 30.0µin (0.76µm) gold or Gold, GXT™ plating on the mating surface handles repeated mating cycles without corrosion — the 5A rating is the practical limit for signal-level duty through a single row of pins.
