Procurement Notes

Verify the specific suffix codes on the ordering information to confirm tolerance, tape-and-reel specifications, and termination finish. Ensure compatibility with your reflow soldering profile by checking the recommended thermal parameters in the official datasheet. Confirm lead-free compliance status if required by your manufacturing standards. Cross-reference the manufacturer's latest documentation to ensure no obsolescence notices apply before finalizing procurement.

Selection Notes

Evaluate the required saturation current and RMS current ratings against your application's peak load conditions to prevent core saturation. Consider the physical dimensions to ensure the component fits within the designated footprint on the printed circuit board. Assess the operating temperature range to guarantee reliability under worst-case thermal scenarios. Compare DC resistance values to optimize efficiency losses in the power path.

Part Context

This component belongs to KEMET's series of shielded power inductors, which are widely used in modern electronics for their ability to manage high currents in small packages. The SH series specifically targets applications requiring minimal magnetic leakage and high stability. These inductors complement KEMET's broader portfolio of passive components used in power management solutions across industrial and consumer sectors.

Replacement Considerations

Consult KEMET's official substitution guide or distributor cross-reference tools for verified equivalent part numbers. Ensure any replacement maintains identical inductance value, current ratings, and physical dimensions. Verify that alternative components meet the same shielding and thermal performance requirements specified in the original design.
