Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to integration. Confirm that the 110 mΩ DCR and 3.1 A current ratings align with your thermal management requirements. Ensure the 1280 package dimensions fit within your defined board clearance zones. Cross-reference the manufacturer's latest mechanical drawings for accurate pad layout specifications.

Arrays, Signal Transformers Selection Notes

Select this component when a dual-inductor solution is required in a single package to save board space. The 47 µH value suits intermediate frequency switching applications. The 3.1 A rating provides sufficient headroom for moderate power loads. Consider the 8.5 mm height constraint during mechanical enclosure design. The shielded type reduces the need for additional magnetic shielding materials.

Arrays, Signal Transformers Part Context

This part belongs to the WE-DD series of coupled inductors from Würth Elektronik. The series focuses on providing integrated magnetic solutions for complex power conversion needs. The 744873470 specifically addresses applications needing two isolated or coupled windings in a standardized SMD form factor.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes must match the 47 µH inductance, 1280 package size, and coupled topology. Verify equivalent current ratings and DC resistance values to ensure thermal compatibility. Check for pin-out consistency if the replacement offers different winding configurations.
