Procurement Notes
Verify the specific datasheet version and RoHS compliance status prior to ordering, as manufacturer documentation may undergo revisions. Confirm that the SMD package dimensions align with the target PCB footprint design. Ensure that the thermal management strategy accommodates the specified operating temperature range during final product integration.
Selection Notes
Select this component when designing circuits requiring integrated magnetics for 10/100 Mbps Ethernet connections with PoE support. The single-port configuration simplifies layout compared to multi-port alternatives. Consider the unshielded nature of the module regarding electromagnetic interference requirements in the final enclosure design.
Part Context
This part belongs to the HX series of LAN transformers from Pulse Electronics. It is categorized under audio and signal transformers, specifically tailored for datacom applications. The module encapsulates the necessary magnetic components to facilitate signal coupling and isolation in standard twisted-pair copper cabling systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative manufacturers or models.
