Fixed Inductors Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before procurement. Confirm that the 22 uH inductance value aligns with your circuit requirements, as variations may exist between similar part numbers or manufacturing batches. Ensure compatibility with your assembly process regarding axial lead spacing and thermal constraints during soldering.

Fixed Inductors Selection Notes

Select this component when a fixed 22 uH inductance with tight 5% tolerance is required for RF applications. Consider its unshielded nature regarding potential magnetic interference in dense layouts. Verify that the 0.96 ohm DC resistance meets your power loss specifications and that the axial form factor fits your board space constraints.
