What it is
The Amphenol ICC 10078770-002LF is the 2-position male-blade power header in the HCI® family. Rated 75 A per circuit at 0.287" (7.30 mm) pitch, it mounts right-angle through-hole with a press-fit tail — the compliant-pin interface eliminates solder in the barrel and is sized for backplane or daughtercard power planes where current density is the constraint. Contact finish is gold or Gold GXT™ at 30.0 µin (0.76 µm) — the GXT option improves endurance on the wiping interface without changing the current ceiling. All positions are loaded. UL94 V-0 housing material supports deployment in confined power-converter enclosures where flammability rating is a compliance gate.
What the ratings mean for the fit
The 75 A per-circuit rating is the load ceiling — the blade geometry and the 30.0 µin gold/GXT plating sustain that current without the temperature rise exceeding the housing limit. For a 2-position header carrying a single power rail, the per-contact rating is the relevant figure; there is no bus-bar de-rating across the pair. Press-fit termination seats the compliant tail into the plated-through hole without wave or reflow — the interference fit holds the pin mechanically and carries current. Verify the via barrel diameter matches the Amphenol HCI press-fit spec for your backplane stack-up. Operating range of -65 °C to 105 °C covers the full span of most enclosed power electronics environments. The -65 °C floor handles outdoor or thermally cycled applications; the 105 °C ceiling is the ambient-or-contact limit before derating kicks in — check the current-derating curve in the Amphenol HCI datasheet if the board runs hot.
Sourcing and compliance
Quoted to order against BOM quantity. Confirm your layout's press-fit hole size against the Amphenol HCI datasheet before specifying — the 0.287" pitch and the right-angle orientation define the footprint boundary, and the board thickness window for press-fit retention must be verified for your backplane stack-up.
