Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Abracon LLC or authorized distributors before procurement. Confirm that the surface-mount footprint dimensions align precisely with the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the isolation voltage specifications against system safety standards.

Selection Notes

Select this component for standard 10/100 Mbps Ethernet designs requiring integrated magnetics. The single-channel configuration suits simple PHY interfaces without PoE requirements. Consider the 350 μH inductance value for impedance matching. Evaluate the 12.6 mm x 6.87 mm footprint against available board space. Verify compatibility with the target soldering profile for SMD/SMT termination.
