ESD-R-28C-1

Overview

The KEMET ESD-R-28C-1 is a nickel zinc ferrite toroidal core designed for electromagnetic interference suppression. It features an inner diameter of 16 mm, an outer diameter of 28 mm, and an external length of 13 mm. The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 300 MHz.

Feature Summary

• Constructed from nickel zinc ferrite material for high-frequency noise attenuation
• Toroidal geometry provides efficient magnetic flux containment
• Designed for free-hanging installation on cables

Applications

• Suppression of electromagnetic interference in high-speed data lines
• Noise filtering on communication cable assemblies
• Common mode choke applications in electronic equipment

Procurement Notes

Verify the specific suffix '-1' against official KEMET documentation to confirm exact dimensional tolerances and material batch specifications. Ensure compatibility with existing cable diameters before integration into final assembly designs.

Selection Notes

Select this component when nickel zinc properties are required for frequencies approaching 300 MHz. Compare physical dimensions against available cable bundles to ensure proper fitment within the designated enclosure space.

Part Context

This part belongs to the ESD-R series of ferrite rings manufactured by KEMET. The series offers various sizes and materials to address different EMI suppression requirements across industrial and consumer electronics sectors.

Replacement Considerations

Consult KEMET technical support for verified cross-reference part numbers. Do not substitute with generic ferrite cores without confirming matching permeability and dimensional constraints.
