Procurement Notes
Verify the specific manufacturer designation, as API Delevan assets were acquired by Coilcraft. Confirm availability through authorized distributors or Coilcraft channels, as original Delevan stock may be limited. Ensure the datasheet matches the exact part number to confirm electrical parameters before integration into production designs.
Selection Notes
Select this component for low-inductance RF applications requiring a compact 1005 metric footprint. The unshielded design suits circuits where magnetic interference is minimal. Verify that the 650 mA current rating meets the operational requirements and that the 230 mOhms DCR aligns with power loss constraints in the target circuit topology.
Part Context
The 103R-101K belongs to the 103/R series of micro chip inductors manufactured by API Delevan. This series is characterized by small surface-mount packages suitable for high-frequency applications. The brand history involves API Delevan's specialization in passive components before industry consolidation.
Replacement Considerations
Coilcraft acquired API Delevan; verify if equivalent models exist within the Coilcraft portfolio. Cross-reference with other 1005 package RF inductors from different manufacturers if supply chain constraints require alternative sourcing.
