Fixed Inductors Procurement Notes

Verify the specific ordering suffix against official Samsung Electro-Mechanics documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with standard SMD reflow soldering profiles. Confirm availability status through authorized distributors as production cycles may vary. Cross-reference the datasheet for precise thermal management requirements during installation.

Fixed Inductors Selection Notes

Select this component when a low-profile, shielded inductor is required for high-current applications. The 4040 footprint offers a balance between current handling capacity and board space efficiency. Consider the 1.2 A current rating relative to peak load demands. The metal composite core is suitable for applications prioritizing reduced magnetic noise compared to unshielded alternatives.

Fixed Inductors Part Context

This part belongs to the CIGW series of power inductors manufactured by Samsung Electro-Mechanics. The series utilizes wire-wound technology with metal composite cores to deliver robust performance in power electronics. The 4040 package size is a standard form factor designed for surface-mount assembly, providing reliable connectivity for modern automated manufacturing processes.

Fixed Inductors Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any alternative maintains identical 4040 dimensions, 470 nH inductance, and comparable current ratings to ensure mechanical and electrical compatibility without redesign.
