USB 2.0 Type-B Receptacle for Board-Edge Duty
The Molex 670688001 is a USB Type-B receptacle from the 67068 series, designed for USB 2.0 data and power interconnect on a PCB. It carries 4 contacts rated 1.5 A at 30 V, with gold-plated contacts that handle the 1500 mating cycles typical of a user-facing port.
This is a right-angle, through-hole mount part with a board lock feature — the two large solder tabs anchor the shell to the PCB, taking the mechanical strain off the signal pins during cable insertion and removal.
What the 1500 Mating Cycles Mean
The gold contact finish resists fretting corrosion over that cycle life, which keeps contact resistance stable for the USB 2.0 signal pair.
