ESD-R-19N-H

Overview

The KEMET ESD-R-19N-H is a solid toroidal ferrite core designed for electromagnetic interference (EMI) noise 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 7.7 mm, an outer diameter of 22.0 mm, and a length of 14.0 mm. It operates within a temperature range of -40°C to +120°C and complies with RoHS 3 standards.

Feature Summary

• Solid construction provides mechanical stability for round cable installation.
• Nickel-Zinc material formulation optimizes performance in the 300 MHz frequency range.
• Free-hanging design allows for easy mounting on cables without additional hardware.

Applications

• Noise suppression on round power and signal cables
• Electromagnetic interference filtering in electronic assemblies
• Common mode choke applications for cable harnesses

Procurement Notes

Verify the specific suffix 'H' confirms the solid NiZn material variant and dimensional tolerances as documented in the official KEMET datasheet. Ensure compatibility with the target cable diameter of approximately 7.7 mm inner bore. Confirm RoHS 3 compliance requirements match project specifications before finalizing procurement orders.

Selection Notes

Select this component when a solid, non-split toroidal core is required for permanent cable installations. The NiZn material is appropriate for higher frequency noise suppression compared to MnZn variants. Verify that the physical dimensions fit the available space and that the operating temperature range meets the environmental conditions of the application.

Part Context

This part belongs to the KEMET ESD-R-H series of EMI cores. The series offers various sizes and materials to address different cable diameters and frequency requirements. The ESD-R-19N-H specifically addresses mid-range cable sizes with solid construction for robust mechanical handling and installation.

Replacement Considerations

Direct substitutes include other KEMET ESD-R-H series parts with matching inner diameter and material properties. Cross-brand replacements require verifying identical magnetic characteristics, physical dimensions, and temperature ratings to ensure equivalent noise suppression performance.
