ESD-R-19B

Overview

The KEMET ESD-R-19B is a solid, free-hanging ferrite core designed for electromagnetic interference suppression on round cables. It features a nickel-zinc (NiZn) material composition suitable for high-frequency applications up to 300 MHz. The component has an inner diameter of 8.80 mm, an outer diameter of 21.50 mm, and a length of 13.00 mm. It is RoHS compliant and operates within a temperature range extending up to +85°C.

Feature Summary

• Solid construction with free-hanging installation type
• Nickel-zinc material optimized for high-frequency noise suppression
• RoHS compliant environmental standard

Applications

• Electromagnetic interference filtering for round cables
• High-frequency signal integrity protection in electronic assemblies

Procurement Notes

Verify the specific manufacturer part number against official KEMET documentation to ensure compatibility with design requirements. Confirm that the NiZn material properties align with the intended operating frequency range. Check for any updated compliance certifications or packaging specifications prior to final procurement decisions.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable assembly. Ensure the cable diameter fits within the 8.80 mm inner diameter specification. Consider the thermal limits and frequency response characteristics relative to the specific EMI spectrum being addressed in the application.

Part Context

This component belongs to the KEMET ESD-R series of ferrite toroids. These cores are engineered for general-purpose EMI suppression. The ESD-R-19B specifically utilizes NiZn material, distinguishing it from MnZn variants used in lower frequency applications. It serves as a passive component for noise reduction in wiring harnesses.
