LCSC-stocked 4.7 µH candidates

PartMPNPackageCurrent ratingDCRNotes
FXL0630-4R7-MFXL0630-4R7-MIND-SMD_L7.0-W6.66 ANot listed in libraryBest library hit. Meets the >= 4.05 A target. DCR must still be checked in datasheet.
PRS6045-4R7MTPRS6045-4R7MTIND-SMD_L6.0-W6.04 ANot listed in librarySlightly below your 4.05 A target.
MHCI05030-4R7M-R8DFMHCI05030-4R7M-R8DFSMD4 ANot listed in libraryAlso slightly below your current target.
Conclusion
From the Flux library metadata alone, only FXL0630-4R7-M clearly meets your current-rating requirement.
The DCR <= 30 mΩ requirement cannot be confirmed from the library records because DCR is not populated for these entries.
Best current candidate What to do next
To finalize this correctly, I should verify the datasheet for:
and confirm:
  • DCR
  • saturation current
  • temperature rise current
If you want, I can do that next.
