USB 3.2 Gen 1 Type-A Receptacle, 9 Contacts, Right-Angle Through-Hole
The Molex 484040003 is a USB 3.2 Gen 1 (USB 3.0 / Superspeed) Type-A receptacle from the 48404 series, carrying 9 contacts in a single-port, right-angle through-hole package. This is the standard upstream-facing USB-A port found on host devices, designed for board-edge mounting where the cable plug inserts parallel to the PCB. The 9-contact layout supports the SuperSpeed differential pair (SSRX+/-, SSTX+/-) plus the legacy USB 2.0 D+/D- and power/ground lines, all in a single shielded shell.
Dual Current Rating and Contact Assignment
The current rating splits into two tiers: 1.8 A per contact on the power delivery pins (VBUS and GND), and 0.25 A per contact on the signal lines. This is typical for USB 3.x receptacles — the higher-current pins handle device charging and bus power, while the signal contacts carry only data. The 30 VAC/DC rating covers the USB bus voltage comfortably. Gold plating on the contacts ensures consistent low resistance over the rated 5000 mating cycles, which is a high-durability spec for a USB port — suited for test equipment, industrial panels, or public kiosk interfaces where the connector sees frequent plug/unplug cycles.
Shielded Shell with Board Lock for Mechanical Retention
The steel/stainless steel shell provides full EMI shielding.
The tray packaging suits automated pick-and-place assembly for the through-hole solder process.
