The Molex 0480370001 is a standard USB-A (USB TYPE-A) plug from the 48037 series, built for USB 2.0 applications. This orientation is common for rear-panel I/O, front bezels, or any enclosure where the USB port needs to be accessible from the side of the board rather than the top.
The pinout follows the standard USB 2.0 assignment: VBUS, D-, D+, and GND. If your design calls for USB 3.0 or 3.1 data rates, this is not the right part — you'd need a 9-contact or 10-contact USB-A with the extra differential pairs.
Shielding and Construction
The 0480370001 is shielded — the shell material is steel (SPCC), which provides EMI containment for the differential pair. The steel shell is grounded through the through-hole solder tabs, bleeding common-mode noise from the cable shield before it reaches the host board. Gold finish on the contacts handles the mating cycle duty of a field-serviceable USB port.
Ratings and Operating Range
Rated 1.5A per contact at 150VAC, with an operating temperature span of -20°C to 85°C. The 1.5A per-contact current covers standard USB power delivery — enough for charging and data peripherals, though not for USB Power Delivery extended profiles. The 150VAC voltage rating is well above the 5V DC typical of a USB bus, so the margin is generous for industrial or telecom environments where transient protection matters. The -20°C low end means it can sit in an unheated enclosure or outdoor kiosk without issue.
