Rated 5A per contact at 110V, with 30.0µin (0.76µm) gold plating on the mating surface — the gold thickness is enough for repeated mating cycles in field-serviceable equipment without risking contact fretting. The through-hole solder termination and 0.120\" (3.05mm) post length suit it for standard PCB thicknesses; the overall 1.040\" (26.42mm) contact length gives enough reach for a mid-board position. The 0.100\" pitch is the classic 2.54mm grid — every DIP IC and prototype board uses it, so the footprint is predictable. 66 positions loaded all means every pin hole on the two rows is populated; there is no optional empty position to verify against the BOM.","metaTitle":"Amphenol 87901-166HLF BergStik II Header, 66 Pos","metaDescription":"Amphenol 87901-166HLF BergStik II unshrouded header, 66 positions, 2 rows, 0.100\" pitch, 5A, 110V, through-hole, gold plating.
