ESD-R-26S

Overview

The KEMET ESD-R-26S is a solid nickel-zinc (NiZn) ferrite core designed for cable electromagnetic interference suppression. It features a cylindrical geometry with an inner diameter of 13.00 mm, an outer diameter of 26.00 mm, and a length of 28.50 mm. The component operates within a temperature range up to +85°C and supports frequencies up to 300 MHz. Classified under the ESD-R series, it utilizes a free-hanging installation method and complies with RoHS3 standards.

Feature Summary

• Constructed from nickel-zinc ferrite material for effective high-frequency noise attenuation
• Solid cylindrical design eliminates the need for assembly tools or snap-on mechanisms
• Engineered for broad-spectrum electromagnetic interference suppression in cable applications

Applications

• Cable noise suppression in electronic assemblies
• Electromagnetic interference filtering for signal and power lines
• General-purpose EMI mitigation in consumer electronics

Procurement Notes

Verify current availability status as the part is listed as obsolete with end-of-life notifications. Confirm final substitution options with the manufacturer prior to procurement planning. Ensure compliance requirements match project specifications, noting RoHS3 certification. Review official datasheets for any recent product change notices affecting form, fit, or function before integration into new designs.

Selection Notes

Select this component when a non-split, solid ferrite solution is required for cables exceeding 13 mm in diameter. The NiZn composition suits higher frequency applications compared to manganese-zinc alternatives. Evaluate thermal constraints against the +85°C maximum operating limit. Consider mechanical stability needs where snap-on cores are unsuitable due to cable stiffness or routing constraints.

Part Context

The ESD-R-26S belongs to KEMET's ESD-R series of solid ferrite cores. This series provides fixed-dimension magnetic components for permanent cable attachment. Unlike split-core variants, these units require threading during initial assembly. The series targets cost-effective, reliable EMI suppression across various industrial and commercial electronic environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult KEMET technical support for direct cross-references or updated series replacements given the obsolete status.
