USB 2.0 Type-A Receptacle for Board-Edge Mounting
The Molex 482580001 is a USB 2.0 Type-A receptacle from the 48258 series, offering 4 contacts in a single port. The shielded brass shell and gold-plated contacts support the USB 2.0 signal standard, rated at 1.5 A per contact and 250 VAC.
This receptacle uses board-edge, right-angle through-hole solder termination.
Current and Voltage Rating
Rated at 1.5 A per contact and 250 VAC, the 482580001 covers the USB 2.0 power envelope (500 mA standard) with margin for low-power charging. The 1.5 A limit is a per-contact figure — the total current through the receptacle depends on the PCB trace width and ambient temperature, but the connector itself is not the bottleneck for typical USB 2.0 duty. The 250 VAC rating is a dielectric withstand spec, not a working voltage for the signal pair; the USB 2.0 differential pair operates at 3.3 V logic levels.
Shielding and Compliance
The shielded brass shell provides EMI containment for the USB 2.0 signal pair, which is essential for passing radiated emissions testing in commercial equipment.
