Procurement Notes

Verify the specific datasheet revision when sourcing, as manufacturer documentation may vary slightly between distributors. Confirm that the required package type matches the target PCB footprint. Ensure compliance with relevant environmental directives such as RoHS if applicable to the final product design. Cross-reference part numbers carefully to avoid confusion with similar series components.

Selection Notes

Select this component for designs requiring a compact, single-port Ethernet solution. It is specifically suited for space-constrained applications like PC Cards where standard RJ45 jacks are impractical. Consider thermal management requirements during SMT reflow processes. Evaluate impedance matching and signal integrity needs against the transformer's specified performance characteristics.
