USB Type-A SMT Receptacle 4 Pin DW-U20-SA430-01TR-03 is a shielded female USB connector designed for surface-mount PCB applications. The Dragon Well drawing confirms a standard 4-contact Type-A interface, SMT contact termination, metal shell retention features, and tape-and-reel packaging for automated production.
The connector is rated at 1.5 A maximum and operates from -25°C to +75°C. Electrical performance includes 30 mΩ maximum contact resistance, 1000 MΩ minimum insulation resistance, and 500 VAC RMS dielectric withstand voltage.
Mechanical specifications for the USB Type-A SMT Receptacle 4 Pin include a maximum insertion force of 3.57 kg and a minimum extraction force of 1.02 kg. The connector body measures approximately 15.80 ±0.25 mm overall width, with a 13.20 ±0.15 mm front shell width, 13.50 ±0.25 mm body depth, and 7.0 ±0.15 mm height.
The housing is made from LCP thermoplastic rated UL 94V-0. Contacts are 0.25 mm brass, while the 0.30 mm brass shell uses nickel plating. For this specific model, plating code 01 specifies gold flash on the mating area. The product is marked RoHS compliant.
This USB Type-A SMT Receptacle 4 Pin is suitable for USB host ports, embedded electronics, industrial control equipment, communication products, consumer electronics, instrumentation, and other compact PCB interfaces. Amphenol and Samtec likewise classify comparable Type-A receptacles with right-angle/surface-mount configurations and flash-gold contact options.
