Fixed Inductors Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and specifications. Confirm RoHS3 compliance status if required by specific project regulations. Check moisture sensitivity level classifications prior to storage and handling procedures. Ensure compatibility with standard surface mount assembly processes.

Fixed Inductors Selection Notes

Select this component when space constraints require a 1008 footprint with integrated shielding. Consider the 1.4 A rated current and 2.2 A saturation limit for load requirements. Evaluate the 150 mΩ DC resistance against efficiency targets. Verify thermal management capabilities within the specified -40°C to 125°C operating range.

Fixed Inductors Part Context

This inductor belongs to the CIGW series of metal composite power inductors designed for surface mount technology. The series emphasizes low profile dimensions suitable for modern PCB layouts. Samsung Electro-Mechanics manufactures these components using specialized winding techniques to achieve consistent electrical characteristics across production batches.

Fixed Inductors Replacement Considerations

Cross-reference with other Samsung CIGW series variants sharing identical 1008 dimensions and 4.7 µH values. Verify that substitute parts maintain equivalent shielding effectiveness and saturation current ratings. Ensure replacement components match the original DC resistance and tolerance specifications.
