Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets have been acquired. Confirm RoHS compliance status through official documentation, as historical records may vary. Ensure the ordering suffix matches the required tolerance and packaging specifications. Cross-reference the datasheet for any updates regarding lead-free status or material changes since the acquisition.

Selection Notes

Select this component for applications requiring compact RF inductors with precise 5% tolerance. The 900 mA current rating suits moderate power levels. Consider the unshielded nature for layout sensitivity. Compare against shielded alternatives if electromagnetic interference mitigation is critical. Verify the 120 mOhm resistance meets efficiency requirements for the target circuit.

Part Context

This part belongs to the 103/R series of RF inductors from Delevan. The series offers various inductance values in a standardized 1010 footprint. These components are engineered for general-purpose RF applications where size constraints and electrical precision are prioritized over magnetic shielding.
