ESD-R-25D

Overview

The KEMET ESD-R-25D is a solid toroidal ferrite core designed for electromagnetic interference suppression on round cables. It features an inner diameter of 14 mm and an outer diameter of 25 mm, with an external length of 15 mm. The component operates within a temperature range of -25°C to +60°C and is rated for frequencies up to 300 MHz. Constructed from nickel zinc material, it provides effective noise attenuation in compact applications.

Feature Summary

• Solid toroidal design for secure cable mounting
• Nickel zinc composition for high-frequency noise suppression
• Snap-on installation capability for rapid deployment

Applications

• Electromagnetic interference filtering for electronic equipment
• Noise suppression on power and signal cables
• Compliance support for EMC standards in consumer electronics

Procurement Notes

Verify the specific suffix designation against official KEMET documentation to confirm exact dimensional tolerances and material specifications. Ensure the selected variant matches the required operating temperature range and frequency characteristics for the target application environment.

Selection Notes

Select this component based on the cable diameter requirement of 14 mm inner bore. Confirm that the nickel zinc material properties align with the targeted noise frequency spectrum. Validate physical clearance constraints against the 25 mm outer diameter and 15 mm length dimensions.

Part Context

This part belongs to the KEMET ESD-R series of solid ferrite cores. These components are engineered for general-purpose EMI suppression. The series offers various sizes to accommodate different cable diameters while maintaining consistent magnetic performance characteristics across the product line.

Replacement Considerations

Consult official KEMET substitution guides for verified alternatives. Cross-reference internal diameter and impedance curves to ensure functional equivalence.
