ESD-R-25M-H

Overview

The KEMET ESD-R-25M-H is a solid MnZn ferrite core designed for electromagnetic interference suppression. It features a circular geometry with an inner diameter of 12.70 mm, an outer diameter of 29.01 mm, and a length of 16.00 mm. The component operates within a temperature range of -40°C to +120°C and is rated for frequencies up to 10 MHz. It complies with RoHS3 standards and is classified under ECCN EAR99.

Feature Summary

• Solid toroidal construction eliminates the need for assembly hardware
• MnZn material composition optimized for low-frequency noise attenuation
• Free-hanging installation design allows direct cable suspension

Applications

• Suppression of electromagnetic interference on round cables
• Common mode noise filtering in electronic assemblies
• EMI mitigation in industrial equipment wiring

Procurement Notes

Verify the specific suffix 'H' against the manufacturer datasheet to confirm dimensional tolerances and material grade. Ensure the required cable diameter falls within the 12.70 mm inner diameter specification. Confirm RoHS3 compliance requirements match the project's regulatory constraints before finalizing procurement.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. The MnZn material is suitable for lower frequency applications compared to NiZn alternatives. Verify that the physical dimensions accommodate the target cable bundle without excessive strain or fitment issues during assembly.

Part Context

This part belongs to the ESD-R-H series of solid ferrite cores manufactured by KEMET. These components are distinct from snap-on cores as they require threading the cable through the center bore during manufacturing or assembly. The series provides a robust solution for fixed wiring environments where split-core accessibility is not available.
