Procurement Notes
Verify that the specific part number matches the required tape and reel configuration if automated placement is needed, as the base suffix indicates tube packaging. Confirm RoHS compliance status through official documentation before finalizing procurement. Ensure design-in compatibility with existing PCB footprints and thermal management requirements.
Selection Notes
Select this component when designing single-port Ethernet solutions requiring integrated PoE support. Compare against non-PoE variants like the HX1260NLT if power delivery is unnecessary. Consider the operating temperature range and isolation voltage requirements to ensure suitability for the target environment and safety standards.
Part Context
This component is part of Pulse Electronics' HX series of audio and signal transformers. It serves as a specialized magnetic solution for local area network connectivity. The product line focuses on providing reliable signal integrity and power transfer for standard Ethernet protocols in compact form factors.
