Procurement Notes
Verify the specific suffix '3J11ET' against official Abracon documentation to confirm exact pinout and mechanical tolerances. Ensure compatibility with target PCB footprint and reflow profiles. Cross-reference RoHS compliance status via the manufacturer's latest datasheet before finalizing procurement decisions.
Selection Notes
Select this component when a compact, shielded LAN transformer is required for Gigabit Ethernet designs. Consider the 18.3 x 12.4 mm surface mount package constraints. Verify that the 350 uH inductance and 1.2 Ohm primary resistance meet the specific PHY requirements of the target application circuit.
Part Context
This part belongs to Abracon's ALAN series of LAN transformers. It serves as a passive magnetic component bridging the Ethernet PHY and the physical medium connector. The design integrates common mode chokes and pulse transformers into a single surface-mount package to simplify board layout.
Replacement Considerations
Consult official Abracon substitution guides for verified alternatives. Generic cross-references may differ in pin configuration or electrical characteristics. Do not assume interchangeability without validating schematic compatibility and mechanical fit.
