Fixed Inductors Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations exist between tape-and-reel and cut-tape formats. Confirm that the selected variant matches the required reel width and terminal wraparound specifications for your pick-and-place equipment. Cross-reference the manufacturer part number against official distribution channels to avoid counterfeit components. Ensure compliance with RoHS3 standards if environmental regulations apply to your assembly process.

Fixed Inductors Selection Notes

Select this component when a compact 0402 footprint is required for low-inductance RF applications. The 27 nH value suits high-frequency filtering where minimal parasitic effects are critical. Consider the 400 mA current rating to ensure the inductor does not saturate under operational load. The unshielded design may require careful layout consideration to minimize electromagnetic interference with adjacent sensitive traces.
