Procurement Notes

Verify the specific ordering suffix to confirm tolerance and packaging details. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the axial package dimensions match the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when high precision inductance is required for RF applications. The 1% tolerance ensures tight control over circuit performance. Consider the 525 mA current rating and 440 MHz self-resonant frequency to ensure suitability for the intended operating frequency range.

Part Context

This part belongs to the Delevan 0819 series of RF inductors. The series offers various inductance values and tolerances. The 0819-10F specifically provides a low-inductance option with high precision, distinguishing it from higher inductance variants within the same family.

Replacement Considerations

Parts such as 0819-10J (5% tolerance) or 0819-10H (3% tolerance) share identical electrical parameters except for tolerance. Verify that the looser tolerance meets the application requirements if substituting.
