Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pinout, tape-and-reel packaging details, and RoHS compliance status. Ensure the selected variant matches the required operating temperature range and inductance tolerance for the target design. Cross-reference terminal counts and package dimensions with the PCB footprint library before finalizing procurement orders.

Selection Notes

Select this component for single-port LAN applications requiring integrated pulse transformation and isolation. The 350 µH inductance value supports standard Ethernet signaling requirements. Consider the surface-mount form factor for automated assembly processes. Verify compatibility with PoE extended temperature specifications if power delivery over Ethernet is required in the application environment.
