The 0.100\" pitch and 0.100\" row spacing put this on the legacy through-hole grid — the footprint is a straightforward 2×36 array of 0.025\" square pins. The overall contact length of 0.940\" with a 0.720\" mating length means the header stands well off the board; the post length of 0.120\" is short, so the solder tail barely protrudes below the PCB. That 0.120\" post is worth checking against your board thickness — on a 0.062\" board you get about 0.058\" of exposed tail for the solder fillet, which is adequate for wave solder but leaves little margin for a thick board. The current ceiling is set by the 0.100\" pitch and the phosphor bronze contact material — the 30.0 µin gold plating doesn't limit current, but the narrow pin cross-section and the housing's UL94 V-0 material's temperature rise curve do. For a 72-position header, the practical limit is the total current through the common plane, not any single pin. The voltage rating of 110 V is conservative for the 0.100\" air gap between unshrouded pins in a typical indoor environment. For vibration-prone assemblies, consider a shrouded header or a separate locking latch.","metaTitle":"Amphenol FCI 87900-172HLF BergStik II Header, 72 Pos","metaDescription":"Amphenol FCI BergStik II unshrouded header, 72 positions (2x36), 0.100\" pitch, 5 A, 110 V, through-hole, 30.0µin gold.
