Standard USB-A Plug for USB 2.0, Right-Angle SMT
The Molex 480371000 is a USB-A (USB TYPE-A) plug from the 48037 series, configured for USB 2.0 with 4 contacts. It is a shielded, right-angle surface-mount connector with additional through-hole retention posts — the SMT pads handle the signal and power lines while the through-hole legs anchor the connector against the insertion and extraction forces of repeated USB mating cycles.
Mounting and Board Layout
The hybrid termination — surface-mount for the four contacts, through-hole for the mechanical posts — means the reflow profile must accommodate both. The SMT pads reflow with the paste; the through-hole legs require either a selective solder wave or a hand-solder touch-up after reflow. The Board Guide feature (molded alignment ribs on the housing) helps locate the part during placement, reducing skew before reflow.
The 1.5 A per pin is typical for a USB 2.0 power line — the VBUS pin can deliver up to 1.5 A to a connected device, which covers the standard USB 2.0 power budget (500 mA for a high-power device) with margin. The 150 VAC rating is unusually high for a USB connector; it reflects the creepage distance across the 3.00 mm pitch contacts and the UL94 V-0 housing material, not the voltage the port will see in a USB application (5 VDC nominal). For the buyer's BOM line, the key fit check is the 4-contact count and the USB 2.0 specification — this plug mates with any standard USB-A receptacle, but the data rate is limited to 480 Mbps by the USB 2.0 spec.
