USB 3.2 Gen 1 Type-A Receptacle, Right-Angle, Shielded
The Molex 484050004 is a USB-A (USB Type-A) receptacle from the 48405 series, carrying 9 contacts and rated for USB 3.2 Gen 1 (also known as USB 3.1 Gen 1 / Superspeed USB 3.0). This is the board-side receptacle that mates with a standard USB-A cable plug.
Current Ratings and Contact Assignment
The 484050004 carries a dual current rating: 0.25 A per contact on the signal pins and 1.8 A per contact on the power/VBUS pins. This is standard for USB 3.x receptacles — the four SuperSpeed differential pairs (eight signal contacts) are rated for signal-level current, while the single VBUS pin handles the higher power delivery. The 1.8 A rating on the power contact is sufficient for USB 3.0 bus-powered devices drawing up to 900 mA, with headroom for inrush. The 0.25 A signal rating is not a limitation for digital data lines; it reflects the contact's capacity in a continuous DC scenario, not the transient signal current.
Through-hole solder termination with a right-angle body and horizontal mounting feature. The board lock consists of two through-hole retention pins that solder into the PCB alongside the signal and power pins, distributing extraction force across the board. The blue insulation color is a visual identifier for the USB 3.0/3.1/3.2 Gen 1 standard (USB 2.0 receptacles are typically black or white).
