Procurement Notes

Verify the specific datasheet revision and manufacturing origin before procurement, as product change notifications may affect physical characteristics such as header design or pin insertion methods without altering electrical function. Confirm compliance with RoHS3 specifications and ensure the supplier provides traceability documentation consistent with current quality standards.

Selection Notes

Select this component when a dual-channel magnetic solution is required for Gigabit Ethernet ports. Ensure the PCB layout accommodates the specified footprint dimensions and that the operating environment remains within the documented thermal limits. Verify compatibility with the target network controller's signaling requirements.

Part Context

This part belongs to the Pulse Electronics LAN Transformers family, specifically categorized under audio and signal transformers. It serves as an encapsulated module replacing discrete transformer components, consolidating isolation and impedance matching functions into a single surface-mount device for compact network hardware designs.

Replacement Considerations

Consult official Product Change Notifications regarding header design modifications. New part numbering schemes may apply to updated versions; verify exact substitution compatibility through manufacturer engineering data rather than assuming direct interchangeability based on model number alone.
