Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with Pulse Electronics or authorized distributors before procurement. Confirm that the SMD footprint dimensions match the target PCB layout requirements. Ensure the operating temperature range aligns with the final system environment constraints. Cross-reference the manufacturer part number to avoid confusion with similar variants like HX1305NL.
Selection Notes
Select this component when designing for 100Base-TX Ethernet interfaces requiring a single-port solution. It is suitable for space-constrained designs due to its small SMD footprint. Consider the 350 µH inductance value for impedance matching requirements. Verify compatibility with the intended signal integrity standards and isolation voltage needs of the application.
Part Context
This component belongs to the Pulse Electronics LAN transformer series, which provides integrated magnetics for Ethernet connectivity. These modules simplify circuit design by combining transformers and common-mode chokes into a single package. The series supports various Ethernet speeds and port configurations, offering reliable signal transmission for networking hardware.
Replacement Considerations
Check for direct substitutes such as the HX1305NL, noting differences in channel count and specific electrical parameters. Verify pinout compatibility and physical dimensions before substitution. Consult official replacement guides from Pulse Electronics for validated alternatives.
