USB-A Plug for Board-Edge Integration
The Molex 480372100 is a USB-A (USB TYPE-A) plug from the 48037 series, designed as a board-edge USB 2.0 interconnect. It carries 4 contacts rated 1.5A each at 150VAC, with gold plating on the contact surfaces for corrosion resistance across repeated mating cycles. The connector is shielded — the steel shell provides EMI containment for the differential data pair, which is necessary to pass radiated emissions limits in commercial equipment.
Mounting Type and Orientation
This plug is offered in a surface-mount, right-angle configuration, with a through-hole option also listed.
USB 2.0 Only — Not Backward Compatible with USB 3.x
The 480372100 is specified for USB 2.0, not USB 3.0 or 3.x. The 4-contact layout carries power (VBUS and GND) and the D+/D- differential pair — there are no SuperSpeed pairs. It will physically mate with a USB 3.0 Type-A receptacle, but data transfer will fall back to USB 2.0 rates. If your design requires USB 3.0 (5 Gbps) or higher, this part will not support it.
