Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the SMD package dimensions align with your PCB footprint design rules. Ensure the operating temperature range meets your system's environmental requirements. Cross-reference the manufacturer part number to avoid confusion with similar series components like HX5008NLT or H5020NLT which may have different port counts or electrical characteristics.

Selection Notes

Select this component when a dual-channel, non-PoE solution is required for Gigabit Ethernet applications. Compare inductance values and insulation ratings against other LAN transformers in the HX series to ensure compatibility with your specific PHY chip requirements. Consider the unshielded nature of the device regarding electromagnetic interference (EMI) constraints in your enclosure design. Verify that the surface-mount form factor fits within your available board space constraints.
