Fixed Inductors Procurement Notes

Verify the specific suffix 'F' indicates the required 1% tolerance level compared to standard variants. Confirm RoHS compliance status as some Delevan series may not meet current environmental directives. Ensure the established reliability designation aligns with project quality requirements before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when high inductance stability and precise tolerance are critical for RF performance. The 390 µH value suits lower frequency filtering tasks where higher self-resonant frequencies are unnecessary. Consider the physical size constraints of the axial package during PCB layout planning.
