The Molex 483910003 is a USB-A receptacle from the 48391 series, built for USB 3.2 Gen 1 (also known as USB 3.0 or SuperSpeed) data rates. Its 9 contacts — four legacy USB 2.0 pins plus five SuperSpeed differential pairs — fit the standard Type-A form factor. A shielded steel shell contains EMI from the 5 Gbps signaling, and the blue insulator visually flags the SuperSpeed capability at a glance.
Through-hole solder tails and integrated board locks anchor the connector against the shear force of repeated plug insertions.
Power and Signal Ratings
The dual current rating — 1.8 A on the power pins and 0.25 A on the signal contacts — matches the USB 3.0 power budget: the VBUS and GND pins carry up to 1.8 A for device charging or bus-powered peripherals, while the SuperSpeed differential pairs handle only signal-level current. The 30 VAC/DC rating covers the USB bus voltage and any downstream power delivery negotiation.
