Fixed Inductors Procurement Notes

Verify the specific datasheet version to confirm current RoHS compliance status and exact electrical tolerances. Ensure the ordering suffix matches the required packaging format, as bulk and reel options may exist within the series. Cross-reference the manufacturer's latest documentation for any updates to mechanical dimensions or material specifications before finalizing procurement.

Fixed Inductors Selection Notes

Select this component when a 3.3 µH inductance value is required with low DC resistance. Consider the axial package size constraints and the unshielded nature of the design regarding magnetic interference. Evaluate the self-resonant frequency against the target application bandwidth to ensure adequate performance at the operating frequency.

Fixed Inductors Part Context
