ESD-R-57S

Overview

The KEMET ESD-R-57S is a solid Mn-Zn ferrite core designed for electromagnetic interference suppression. It features a circular geometry with an inner diameter of 36.00mm, an outer diameter of 57.00mm, and a length of 20.00mm. Classified as a cable ferrite within the ESD-R series, this component utilizes a free-hanging installation type suitable for wrapping around cables. The material composition ensures effective noise attenuation in high-frequency applications.

Feature Summary

• Constructed from manganese-zinc (Mn-Zn) ferrite material for robust magnetic performance
• Solid design provides structural integrity without requiring assembly hardware
• Free-hanging configuration allows flexible placement on various cable diameters

Applications

• Electromagnetic interference suppression on power cables
• Common mode noise reduction in industrial wiring
• Signal line filtering for electronic equipment

Procurement Notes

Verify the specific suffix 'S' against official KEMET documentation to confirm material properties and dimensional tolerances. Ensure compatibility with target cable diameters before integration. Cross-reference RoHS compliance status with current regulatory requirements for your region. Confirm package quantity details directly with authorized distributors.

Selection Notes

Select this component when a large aperture is required for thick cables or bundles. The Mn-Zn composition offers high permeability for low-frequency noise suppression compared to NiZn alternatives. Evaluate thermal stability requirements against the operating environment. Consider mechanical clearance constraints due to the substantial outer diameter dimensions.

Part Context

This part belongs to the KEMET ESD-R series of solid ferrite cores. These components are engineered specifically for cable wrapping applications rather than printed circuit board mounting. The series provides standardized dimensions for consistent noise suppression performance across various industrial and commercial electronic systems.

Replacement Considerations

No public substitute part numbers are documented for this specific model.
