ESD-R-17S

Overview

The KEMET ESD-R-17S is a solid nickel-zinc ferrite toroidal core designed for electromagnetic interference (EMI) suppression. It features an inner diameter of 9.4 mm, an outer diameter of 17.7 mm, and an external length of 28.8 mm. The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 300 MHz. Packaged in bulk, this free-hanging core serves as a passive filtering element for cable assemblies.

Feature Summary

• Constructed from nickel-zinc ferrite material for effective high-frequency noise attenuation
• Solid toroidal geometry allows for easy installation onto existing cable bundles
• Designed specifically for suppressing electromagnetic interference in electronic systems

Applications

• Cable assembly noise suppression
• Electromagnetic interference filtering
• Electronic equipment signal integrity enhancement

Procurement Notes

Verify the specific suffix designation against official documentation, as variations may exist within the ESD-R series. Confirm that the intended application aligns with the specified operating temperature limits and frequency characteristics. Ensure compatibility with the target cable diameter before procurement to guarantee proper fit and performance.

Selection Notes

Select this component when a solid, non-snap-on ferrite core is required for permanent or semi-permanent cable installations. Consider the physical dimensions to ensure adequate clearance around the cable bundle. Evaluate the nickel-zinc material properties against the specific frequency spectrum of the noise being suppressed to ensure optimal impedance matching.

Part Context

This part belongs to the KEMET ESD-R series of solid ferrite toroids. These components are distinct from snap-on cores due to their fixed geometry and manufacturing process. They are categorized under passive EMI filtering elements and are commonly used in industrial and consumer electronics to meet regulatory compliance standards for emissions.

Replacement Considerations

Consult official KEMET documentation for confirmed substitute part numbers. Verify dimensional compatibility and material composition when evaluating alternatives. Do not assume functional equivalence based on similar naming conventions without cross-referencing technical specifications.
