Procurement Notes

Verify the specific ordering suffix ensures compliance with required environmental standards such as RoHS directives. Confirm the moisture sensitivity level (MSL) rating matches your manufacturing process capabilities to prevent damage during reflow soldering. Ensure the package type aligns with your PCB footprint design and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact solution for expanding USB connectivity is required without external host overhead. Consider the power budget of the target system to determine if self-powered or bus-powered configuration is necessary. Evaluate the available pin count and package dimensions against the mechanical constraints of the intended enclosure design.
