Procurement Notes

Verify the specific manufacturer source, as API Delevan operations have undergone structural changes. Confirm RoHS compliance status directly with the supplier or authorized distributor documentation. Ensure the part number matches the exact suffix requirements for your assembly process. Check for obsolescence notices or lifecycle status updates from the original manufacturer before finalizing procurement plans.

Selection Notes

Select this component when an unshielded 1 µH inductor is required for RF environments where magnetic interference isolation is not critical. The low DC resistance and specified current rating suit moderate power RF paths. Consider the physical dimensions against available board space. Verify thermal performance within the stated operating temperature range for the specific application environment.

Part Context

This component belongs to the 103/R series of fixed RF inductors manufactured by Delevan. The series offers various inductance values in a consistent small outline footprint. These parts are designed specifically for high-frequency circuit applications requiring precise inductance stability and low loss characteristics typical of ferrite-core SMD designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires verifying identical electrical parameters, including 1 µH inductance, 0.54 Ω DCR, and 2.54 x 2.54 mm footprint.
