ESD-SR-S38M

Overview

The KEMET ESD-SR-S38M is a manganese-zinc (Mn-Zn) ferrite snap-on core designed for electromagnetic interference suppression. It features a round shape with an inner diameter of 18 mm, an outer diameter of 44 mm, and an external length of 16.5 mm. The component operates within a temperature range of -40°C to +85°C and is rated for free-hanging installation. This part belongs to the ESD-SR series and is packaged in bulk quantities.

Feature Summary

• Snap-on design allows for easy installation over existing cables without disconnection
• Manganese-zinc material composition provides effective high-frequency noise attenuation
• Round geometry accommodates single cable configurations

Applications

• Electromagnetic interference filtering in electronic circuits
• Suppression of common-mode noise on power and signal lines
• Compliance enhancement for consumer electronics emissions standards

Procurement Notes

Verify the specific Mn-Zn material grade and dimensional tolerances against the official KEMET datasheet before integration. Confirm that the 18 mm inner diameter matches the target cable bundle size to ensure proper magnetic coupling. Check for UL94 flammability ratings if required by your application safety standards.

Selection Notes

Select this component when a large aperture is required for thick cables or multi-conductor bundles. The Mn-Zn material is suitable for lower frequency noise suppression compared to Ni-Zn alternatives. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits for reliable performance.

Part Context

This ferrite clamp is part of KEMET's ESD-SR Snap-on Cores family, which focuses on providing flexible EMI solutions for various cable diameters. The series includes multiple sizes and materials to address different noise profiles and physical constraints in modern electronic assemblies.

Replacement Considerations

Direct substitutes must match the 18 mm inner diameter and similar Mn-Zn characteristics. Verify cross-reference availability through authorized distributors to ensure identical electrical and mechanical specifications.
