Fixed Inductors Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm specific packaging requirements, such as reel quantities, against official distributor data sheets. Ensure the ordering suffix matches the required tape and reel configuration. Cross-reference manufacturer part numbers with authorized distributor identifiers to prevent sourcing errors during procurement.

Fixed Inductors Selection Notes

Select this component for applications requiring precise 1.5 µH inductance with tight 1% tolerance. Evaluate the 560 mA current rating and 220 mΩ resistance against circuit power dissipation limits. Consider the 140 MHz self-resonant frequency to ensure operation remains below the parasitic resonance point. Verify that the axial package fits the available PCB footprint and assembly constraints.
