ESD-R-25SD

Overview

The KEMET ESD-R-25SD is a solid manganese zinc ferrite toroidal core designed for electromagnetic interference suppression on round cables. It features an internal diameter of 15 mm, an external diameter of 25 mm, and an axial length of 12 mm. The component operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Solid construction provides mechanical stability for cable routing
• Manganese zinc material optimizes high-frequency noise attenuation
• Snap-on design facilitates rapid installation without cable disconnection

Applications

• Noise suppression for round data cables
• Electromagnetic interference filtering in consumer electronics
• Signal integrity enhancement in industrial control wiring

Procurement Notes

Verify the specific suffix designation against official KEMET documentation to confirm material composition and impedance characteristics. Ensure the procurement specification matches the required internal diameter and operating temperature range for the target application environment.

Selection Notes

Select this component when a solid, non-split ferrite geometry is required for permanent cable assembly. Confirm that the 15 mm aperture accommodates the target cable bundle diameter while maintaining sufficient magnetic coupling for effective noise reduction at the intended frequency spectrum.

Part Context

This part belongs to the ESD-R series of solid ferrite cores manufactured by KEMET. These components are engineered specifically for suppressing common-mode noise on round cables, offering a robust alternative to split-core designs where continuous magnetic circuit integrity is prioritized over field-installation flexibility.
