Its headline spec is the 10000 mating cycle rating. The spec lists three current ratings — 0.5A, 1A, and 1.8A — which likely correspond to the VBUS, D+/D- signal, and ground contacts respectively in a standard USB 2.0 pinout. The 1.8A on the power and ground pins is enough for fast-charging protocols up to 9W at 5V, while the signal contacts carry the 0.5A typical for USB data lines. The 30VAC/DC voltage rating covers the full USB voltage envelope including USB-C power delivery negotiation voltages. ## Unshielded — plan for EMI in the system This is an unshielded receptacle — the steel, stainless shell provides mechanical retention but no EMI containment. For designs with sensitive RF or high-speed data lines, the system-level shielding must come from the enclosure or a separate ferrite. The shell/shielding material is steel, stainless, which gives mechanical robustness but not a continuous ground plane around the signal contacts. Termination is solder, with a board cutout and surface mount mounting type. The horizontal mid-mount feature means the connector body sits partially below the PCB surface — the cutout in the board allows the receptacle to sit lower, reducing the overall height above the board. The solder retention pads on the shell provide additional hold during reflow and against the lever-out force of a plugged-in cable.","metaTitle":"JST UB-MC5BR3-M404-4S-TB NMP USB Micro-B Receptacle","metaDescription":"JST UB series USB micro-B receptacle, 5 contacts, horizontal mid-mount SMT, gold plating, rated 30VAC/DC, 10000 mating cycles.
