Applications

• Three-phase power line filtering
• Industrial equipment EMI suppression
• Power supply input stages

Procurement Notes

Verify the complete part number including suffixes to ensure correct tolerance and packaging specifications. Confirm that the 4A current rating and 10mH inductance align with the specific circuit requirements before procurement. Check datasheets for mechanical dimensions to ensure compatibility with existing board layouts.

Selection Notes

Select this component when high inductance is required for common mode noise reduction in three-phase applications. Ensure the operating environment meets the minimum temperature specification. Verify that the physical size accommodates the through-hole footprint constraints of the target design.

Part Context

This component belongs to the KEMET SCR series, which utilizes toroidal coils with nanocrystalline metal cores. These coils are characterized by ultra-high inductance and permeability, making them suitable for demanding power filtering applications where standard ferrite cores may be insufficient.

Replacement Considerations

Check for compatible parts within the same SCR series or equivalent nanocrystalline common mode chokes from other manufacturers. Ensure substitute components match the 10 mH inductance, 4A current rating, and through-hole package dimensions.
