ESD-SR-250HL

Overview

The KEMET ESD-SR-250HL is a Ni-Zn ferrite snap-on core designed for electromagnetic interference suppression. It features a hinged design for easy installation on round cables without disconnection. The component has an inner diameter of 13 mm and external dimensions of 30 mm x 13 mm x 42 mm. It is rated for AEC-Q200 automotive standards, ensuring reliability in harsh environments.

Feature Summary

• Hinged snap-on design allows rapid installation on existing cable assemblies
• Ni-Zn material composition provides effective high-frequency noise attenuation
• AEC-Q200 qualification ensures suitability for demanding automotive applications

Applications

• Automotive wiring harness noise suppression
• Consumer electronics cable protection
• Industrial equipment EMI filtering

Procurement Notes

Verify the specific suffix HL against official KEMET documentation to confirm AEC-Q200 compliance and exact dimensional tolerances. Ensure the supplier source provides traceability for automotive-grade components. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit or non-compliant variants.

Selection Notes

Select this component when a split-core solution is required for retrofitting or assembly line efficiency. The 13 mm aperture accommodates standard cable bundles. Confirm that the Ni-Zn frequency characteristics align with the target noise spectrum. Verify space constraints within the enclosure against the 42 mm length dimension.

Part Context

This part belongs to the ESD-SR Snap-on Cores series from KEMET. It serves as a specialized variant optimized for automotive durability compared to standard industrial versions. The series offers various aperture sizes to fit different cable diameters while maintaining consistent magnetic performance characteristics across the product line.

Replacement Considerations

ESD-SR-250 is the solid version; verify if hinged access is mandatory. ESD-SR-250HL is the direct equivalent with automotive rating.
