Procurement Notes

Verify the specific suffix (e.g., FNL) against official datasheets to confirm exact inductance values and packaging type. Ensure compatibility with RoHS directives if required by your manufacturing process. Cross-reference pinout diagrams with your PCB layout to prevent installation errors during assembly.

Selection Notes

Select this component when designing Gigabit Ethernet ports requiring integrated magnetics. Consider the 1.5 kV isolation rating for safety compliance. Verify that the 120µH/350µH inductance profile matches your PHY chip requirements. Check thermal limits against your system's operating environment.

Part Context
