Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm exact tolerance and current ratings against specific datasheet revisions prior to integration. Ensure axial lead dimensions match target PCB footprint requirements. Validate supplier authenticity through authorized channels given potential availability constraints.

Selection Notes

Select this component for designs requiring 4.7 uH inductance with moderate current handling capabilities up to 150 mA. Consider the unshielded nature for layout planning to minimize interference. Verify that the 16 MHz self-resonant frequency aligns with operational bandwidth needs. Compare physical dimensions against available board space constraints.
