ESD-R-25D-1

Overview

The KEMET ESD-R-25D-1 is a solid, free-hanging ferrite core designed for cable suppression. It features a Nickel Zinc (NiZn) material composition suitable for high-frequency applications up to 300 MHz. The component has an inner diameter of 14.00 mm (0.551 inches), an outer diameter of 26.00 mm (1.024 inches), and a length of 15.00 mm (0.591 inches). It is classified as a toroidal ferrite ring with a solid design.

Feature Summary

• Solid construction for secure cable retention
• Nickel Zinc material for high-frequency noise suppression
• Free-hanging installation type

Applications

• Cable EMI suppression
• High-frequency signal line filtering
• Electronic equipment noise reduction

Procurement Notes

Verify the specific Nickel Zinc material grade and frequency response characteristics against your application requirements. Confirm that the physical dimensions match your cable bundle size. Check for RoHS compliance status in the official datasheet before finalizing procurement specifications.

Selection Notes

Select this component when NiZn material properties are required for frequencies around 300 MHz. Ensure the 14 mm inner diameter accommodates the target cable or wire gauge. Compare performance against MnZn alternatives if lower frequency attenuation is needed.

Part Context

This part belongs to the KEMET ESD-R series of solid ferrite cores. These components are engineered for easy installation on existing cables without disconnection. The series offers various sizes and materials to address different electromagnetic interference challenges across industrial and consumer electronics.

Replacement Considerations

Direct substitutes include other KEMET NiZn toroids with similar dimensions, such as the ESD-R-25D. Verify material composition and dimensional tolerances before swapping.
