Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm pinout, shielding status, and packaging type. Ensure the selected variant matches the required thermal management and mechanical footprint constraints for the target PCB layout. Cross-reference datasheet revisions to confirm compliance with current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when designing non-PoE Ethernet links requiring high-frequency signal integrity and galvanic isolation. Confirm that the 24-pin SMD package fits the available board space and that the 1.5 kV isolation rating meets system safety requirements. Validate that the operating temperature range aligns with the intended deployment environment and that the 350 µH inductance is compatible with the connected transceiver specifications.
