The Amphenol Airmax VS® 10028916-4455P00LF is a 4-position receptacle blade power connector designed for high-current daughtercard power delivery in backplane systems. The press-fit termination and through-hole mounting suit it for solderless backplane assembly where reliability and reworkability matter. The 2-row × 2-column layout (4 power positions) mates with a complementary header to feed a line card from the backplane.
What the 80 A rating means for the fit
80 A per contact is well above typical signal-level current. Each blade in this 4-position receptacle carries enough current for a power bus or a single high-draw load. The press-fit termination avoids solder-joint fatigue under thermal cycling, which is the failure mode you watch for at these current levels.
The only peer with identical specs and packaging is the 10028916-4554P00LF, which shares the same 80 A, 150 V, press-fit, gold 30.0 µin, and Tube delivery. That gives a second sourcing path without requalifying the footprint.
