The UB-MC5BR3-SD204-4S-TB NMP: This is a JST UB series USB micro-B receptacle, 5 contacts, designed for surface-mount right-angle attachment to a PCB. It is the device-side connector for USB 2.0 OTG or charging ports in compact electronics — tablets, handheld instruments, portable medical gear, or embedded modules. The current rating varies by contact: 0.5A, 1A, and 1.8A across the five positions. In practice, the VBUS pin carries the higher current for charging, while the data lines run at the lower rating.
The connector terminates via solder to the PCB — no crimp or press-fit option. The mounting feature is horizontal (right-angle), so the mating axis is parallel to the board surface. The insulation is black, and the shell material is steel, stainless — providing mechanical robustness without magnetic interference concerns.
The connector is unshielded, so it does not provide EMI containment at the port — plan for external board-level shielding if the design requires it.
