Fixed Inductors Procurement Notes

Verify the specific manufacturer source, as listings reference both API Delevan and generic Delevan. Confirm RoHS compliance status, as some sources indicate 'N' while others suggest lead-free availability. Ensure the supplier provides official datasheets to validate the 2.75 Ohm DCR and 351 mA rating against potential generic variations.

Fixed Inductors Selection Notes

Select this component for high-precision RF designs requiring stable inductance. The unshielded design may require careful PCB layout to minimize electromagnetic interference coupling. Verify that the 351 mA current rating meets the application's peak load requirements without saturation.

Fixed Inductors Part Context

This part belongs to the 5022R series of surface-mountable fixed inductors manufactured by API Delevan. The series is characterized by wirewound technology suitable for radio frequency environments. The 5022R-473F specifically targets applications needing precise 47 µH values with tight manufacturing tolerances.

Fixed Inductors Replacement Considerations

Cross-reference with other 47 µH ±1% unshielded SMD RF inductors from API Delevan or compatible manufacturers. Verify physical footprint compatibility and thermal performance characteristics before substitution.
