Procurement Notes
Verify the specific datasheet version for the 103R-120KS to confirm RoHS compliance status and exact electrical tolerances. Ensure that the ordering suffix matches the required packaging format, as variations may exist between reel and cut-tape options. Cross-reference the manufacturer's latest documentation to validate lead times and availability before finalizing procurement plans.
Selection Notes
Select this component for applications requiring low inductance values in the nano-Henry range. The 1.19 A current rating suits moderate power RF circuits. Consider the unshielded nature when designing layouts to prevent coupling with nearby sensitive traces. Verify that the 12 nH value aligns with the target frequency response requirements of the specific RF application.
Part Context
This part belongs to the Delevan 103/R series of fixed RF inductors. These components are designed for high-frequency applications where small form factors are critical. The series offers various inductance values while maintaining consistent physical dimensions, facilitating standardized PCB footprints across different circuit designs.
Replacement Considerations
Consult official substitution guides for equivalent unshielded SMD RF inductors with similar 12 nH specifications. Verify that alternative parts match the 1.19 A current rating and 69 mΩ DC resistance to ensure circuit compatibility.
