ESD-R-25SR-P

Overview

The KEMET ESD-R-25SR-P is a cylindrical ferrite core designed for electromagnetic interference suppression. It features an inner diameter of 15.4 mm and an outer diameter of 25.9 mm, with a total length of 13.7 mm. The component belongs to the ESD-R-SR series and is constructed from nickel-zinc material. It is rated for operation at frequencies up to 10 MHz.

Feature Summary

• Snap-on design allows for rapid installation onto round cables without disconnection
• Nickel-zinc composition provides effective high-frequency noise attenuation
• Free-hanging configuration enables flexible mounting in constrained spaces

Applications

• Electromagnetic interference filtering on power cables
• Signal line noise suppression in electronic assemblies
• Common mode choke applications for data transmission lines

Procurement Notes

Verify the exact part number against official KEMET documentation to confirm dimensional tolerances and material specifications. Ensure compatibility with cable diameters within the specified inner diameter range. Check for RoHS compliance status if required by your manufacturing standards. Confirm availability through authorized distributors as supply levels may vary.

Selection Notes

Select this component when a snap-on ferrite core is required for cables with an inner diameter near 15.4 mm. The nickel-zinc material is suitable for higher frequency applications compared to manganese-zinc alternatives. Consider the free-hanging form factor for applications where rigid mounting is not feasible or desired.

Part Context

This part is part of KEMET's EMI suppression portfolio, specifically the ESD-R-SR series of snap-on cores. These components are engineered to provide immediate noise reduction solutions for various electronic systems. The cylindrical shape accommodates round cables, making it versatile for different wiring configurations.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate alternative cylindrical ferrite cores with matching inner and outer dimensions. Verify that replacement materials offer comparable impedance characteristics at the target operating frequency.
