Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to ordering, as manufacturing updates may occur. Confirm that the SMD package dimensions align with your PCB footprint requirements. Ensure that the thermal management strategy accounts for the operating temperature range specified in the official documentation. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when designing automotive Ethernet nodes requiring integrated MDI/MDIX switching capabilities. It is appropriate for space-constrained layouts due to its compact surface mount form factor. Consider the 1.5 kV isolation rating for safety-critical network segments. Evaluate the 350uH inductance value against the impedance matching requirements of the connected PHY transceiver to ensure signal integrity.
