Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm tolerance and packaging configuration, as variations exist within the series. Confirm RoHS3 compliance status prior to integration into environmentally regulated assemblies. Check manufacturer announcements for obsolescence notices or production changes that may affect long-term supply stability. Ensure storage conditions align with moisture sensitivity level requirements during handling.

Fixed Inductors Selection Notes

Select this component when a small form factor is required alongside moderate current handling capabilities. The unshielded design necessitates careful layout planning to minimize electromagnetic interference with adjacent sensitive traces. Evaluate the 630 mOhm DC resistance impact on power efficiency for low-voltage applications. Consider the 3.2 GHz self-resonant limit to ensure adequate performance margin for the target operating frequency.
