Pulse Transformers Procurement Notes

Verify the specific suffix 'T' indicates the tape-and-reel packaging variant distinct from tube-packaged equivalents. Confirm RoHS compliance status and MSL rating prior to assembly. Cross-reference manufacturer part numbers with distributor codes to ensure correct sourcing of the 1000Base-T rated component.

Pulse Transformers Selection Notes

Select this model for designs requiring a compact, single-port solution for Gigabit Ethernet connectivity. Ensure the PCB footprint matches the 16.51mm x 9.27mm outline. Consider the operating temperature range of 0°C to 70°C against environmental requirements. Verify compatibility with non-PoE or PoE architectures as specified by the system design.

Pulse Transformers Part Context

This component belongs to Pulse Electronics' LAN transformer series. It serves as a critical passive element in Ethernet physical layer circuits. The module integrates primary and secondary windings into a single surface-mount device. It replaces discrete transformer components to save board space.

Pulse Transformers Replacement Considerations

HX5120NLT is a related variant with extended temperature ratings (-40°C to 85°C). Verify pinout and mechanical compatibility before substitution. Check datasheet differences regarding thermal performance and impedance matching.
