It carries 4 contacts, the classic USB 2.0 pinout (VBUS, D-, D+, GND), rated 1.5A at 30VDC. Board locks on the solder tabs anchor the connector through reflow and repeated cable insertions — without them, the shear force from a stiff USB cable can lift the pads over time.
Why the 1.5A Rating Matters
At 1.5A per port, this is a USB 2.0 power envelope — enough to charge a phone or power a thumb drive, but not the 3A+ that USB 3.0 BC 1.2 or USB-C PD demands. The 30VDC voltage rating covers the 5V USB bus with plenty of headroom; the limiting factor is the contact-beam current capacity and the temperature rise inside the housing. If your design needs higher charging current, look at a USB-C receptacle rated 3A or more.
The white insulator colour is a visual aid for alignment on the pick-and-place line, though the part ships in tray packaging, not tape-and-reel.
