Procurement Notes

Verify the specific suffix (e.g., NL vs NLT) against the official datasheet to confirm packaging type and reel specifications. Ensure the revision level matches the current production version. Confirm RoHS compliance status and moisture sensitivity classification prior to integration into the manufacturing process.

Selection Notes

Select this component when a pre-integrated solution for 10GBASE-T is required to reduce board space and assembly complexity. The integrated connector module eliminates the need for separate magnetics and jack assembly. Verify that the 120µH inductance and 1.5kVRMS isolation rating meet the specific circuit requirements.

Part Context

This part belongs to Pulse Electronics' LAN transformer portfolio, specifically engineered for Ethernet connectivity. It serves as a critical isolation component between the PHY chip and the RJ45 port, ensuring signal quality and electrical safety in high-speed networking environments.

Replacement Considerations

Check for updated revisions such as H7018FNLT or H7018NLT. Verify pinout compatibility and mechanical footprint before substitution. Consult the manufacturer's product change notification for any functional updates.
