ESD-R-12N-H

Overview

The KEMET ESD-R-12N-H is a solid, free-hanging ferrite toroid core designed for electromagnetic interference (EMI) suppression on round cables. Constructed from Ni-Zn material, it operates effectively up to 300 MHz and withstands temperatures between -40°C and +120°C. The component features an inner diameter of 5.00 mm, an outer diameter of 15.00 mm, and a length of 9.00 mm.

Feature Summary

• Solid construction eliminates the need for assembly hardware
• Ni-Zn composition provides high permeability at elevated frequencies
• Free-hanging design allows direct cable insertion

Applications

• Suppression of common-mode noise on power cables
• Filtering data lines in industrial communication systems
• EMI reduction in automotive wiring harnesses

Procurement Notes

Verify the specific suffix 'H' against official KEMET documentation to confirm material grade and temperature rating. Ensure the selected distributor sources genuine components directly from authorized channels to avoid counterfeit ferrite cores with degraded magnetic properties.

Selection Notes

Select this model when a compact, pre-formed toroid is required for cables with a 5.00 mm diameter. The Ni-Zn material is suitable for applications operating above 10 MHz. Confirm that the ambient temperature does not exceed +120°C during operation.

Part Context

This component belongs to the ESD-R series of EMI suppression cores manufactured by KEMET. The series offers various dimensions and materials to address different cable sizes and frequency requirements in electronic equipment.

Replacement Considerations

Consult KEMET technical support for verified cross-references. Generic Ni-Zn toroids may differ in initial permeability and saturation characteristics.
