Procurement Notes
Verify the specific suffix 'XNL' against the manufacturer's current datasheet to confirm RoHS compliance status, as some variants may differ. Ensure the surface mount footprint dimensions match the PCB layout requirements. Confirm that the 350 µH inductance specification meets the impedance matching needs of the target Ethernet PHY controller.
Selection Notes
Select this component when designing Gigabit Ethernet interfaces requiring robust magnetic isolation. The wide operating temperature range makes it suitable for industrial or automotive-grade deployments. Consider the SMT package size constraints during board layout planning to ensure adequate clearance for the transformer body.
Part Context
This part belongs to the 1000B series of LAN pulse transformers from iNRCORE, LLC. The series is engineered for high-reliability networking applications, offering consistent performance in converting differential signals while maintaining electrical isolation between the PHY and the magnetics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing pinout configurations and electrical parameters before considering alternative sources.
