ESD-R-25MK

Overview

The KEMET ESD-R-25MK is a solid cylindrical ferrite core designed for electromagnetic interference suppression. Constructed from Manganese Zinc (MnZn) material, it features an inner diameter of 14.8 mm, an outer diameter of 25.3 mm, and a length of 12.3 mm. Rated for a maximum operating temperature of +85°C, this component provides effective noise filtering for round cables in electronic assemblies.

Feature Summary

• Solid cylindrical construction for secure cable mounting
• Manganese Zinc (MnZn) composition for high permeability
• Coated surface finish for environmental protection

Applications

• Electromagnetic interference suppression on round cables
• Noise filtering in electronic equipment assemblies
• Cable harness EMI mitigation

Procurement Notes

Verify the MnZn material specification and dimensional tolerances against the official datasheet to ensure compatibility with specific cable diameters. Confirm RoHS compliance status and maximum operating temperature ratings prior to integration into final designs.

Selection Notes

Select this component when a solid, non-split ferrite design is required for permanent cable installation. The MnZn material offers superior low-frequency performance compared to NiZn alternatives, making it suitable for general-purpose EMI suppression where high-temperature stability up to 85°C is sufficient.

Part Context

This part belongs to the ESD-R series of solid ferrite cores manufactured by KEMET. It serves as a passive component for managing conducted emissions in electronic systems, distinct from snap-on or split-core variants that allow installation after cable termination.
