ESD-R-25D-8

Overview

The KEMET ESD-R-25D-8 is a solid, free-hanging ferrite core designed for electromagnetic interference suppression. It features an inner diameter of 15.00mm (0.591 inches), an outer diameter of 25.00mm (0.984 inches), and a length of 8.00mm (0.315 inches). The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 300 MHz.

Feature Summary

• Solid construction provides mechanical stability for cable attachment
• Free-hanging design allows flexible installation on round cables
• Optimized for high-frequency noise attenuation up to 300 MHz

Applications

• Electromagnetic interference suppression in consumer electronics
• Cable noise filtering for data and power lines
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific suffix '8' corresponds to the required physical dimensions and material composition. Confirm RoHS compliance status with the manufacturer or authorized distributor prior to finalizing procurement orders. Ensure the selected variant matches the intended operating temperature range requirements.

Selection Notes

Select this component when a compact, solid ferrite ring is needed for cables with a 15mm aperture. Consider the 300 MHz frequency rating and -25°C to +85°C operational limits against system requirements. Evaluate the free-hanging mounting style for ease of integration into existing cable harnesses.

Part Context

This part belongs to the ESD-R series of ferrite cores manufactured by KEMET. These components are engineered for general-purpose EMI suppression applications. The series offers various sizes and materials to accommodate different cable diameters and frequency spectra.

Replacement Considerations

Direct substitutes must match the 15mm ID, 25mm OD, and 8mm length dimensions. Verify that alternative parts support the same 300 MHz frequency range and thermal specifications.
