Fixed Inductors Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain solderability and electrical integrity during assembly processes.

Fixed Inductors Selection Notes

Select this component when space constraints require a 0402 package size alongside specific 12 nH inductance values. Consider the 100 mA current rating and 3.4 ohm DCR limits against circuit power dissipation requirements. Evaluate the 3.8 GHz self-resonant frequency to ensure operation remains below the resonance point for effective inductive behavior.
