Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Sumida documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, as variations may exist within the product line. Check RoHS compliance status directly from the datasheet or supplier declarations before integration into regulated assemblies.

Fixed Inductors Selection Notes

Select this component when a shielded, high-current radial inductor is required for power applications. The 3.3 A rating and low DC resistance make it suitable for efficient energy storage. Ensure the PCB layout accommodates the 5 mm lead spacing and 17.5 mm height constraint for proper mechanical fit.

Fixed Inductors Part Context

This part belongs to the RCP1317 series of power inductors from Sumida. The series utilizes ferrite drum cores and offers magnetic shielding. Other variants in the family include different inductance values such as 68 µH and 390 µH, sharing similar physical footprints and mounting characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes require matching the 47 µH inductance, 3.3 A current rating, and 69 mΩ resistance. Verify that alternative components maintain the same radial package dimensions and shielding requirements to ensure compatibility with existing board layouts.
