Procurement Notes

Verify the specific part number suffix against official KEMET documentation to ensure correct material composition and dimensional tolerances. Confirm that the nanocrystal core variant matches the intended frequency response requirements for the target application design.

Selection Notes

Select this component when nanocrystal permeability is required for low-frequency noise reduction. Ensure the physical dimensions fit the available board space and that the operating temperature range aligns with the environmental conditions of the final assembly.

Part Context

This item belongs to the KEMET ESD-R series of ferrite and nanocrystal cores. These components are engineered for EMI suppression in electronic systems where standard ferrites may not provide sufficient attenuation at lower frequencies.

Replacement Considerations

Consult official KEMET substitution guides for compatible alternatives. Verify that any substitute maintains identical nanocrystal properties and dimensional constraints to ensure circuit compatibility.
