ESD-R-31-P

Overview

The KEMET ESD-R-31-P is a solid, free-hanging ferrite toroidal core designed for electromagnetic interference suppression. Constructed from Mn-Zn material with a green coating, it features an inner diameter of 19.00 mm, an outer diameter of 32.00 mm, and a length of 15.80 mm. This component belongs to the ESD-R series and is intended for use with round cables in low-frequency applications.

Feature Summary

• Solid toroidal design for secure cable mounting
• Mn-Zn ferrite material composition
• Green coated surface finish

Applications

• Low frequency EMI suppression
• Round cable noise filtering

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm exact dimensional tolerances and material properties. Ensure the selected variant matches the required inner diameter for the target cable assembly. Cross-reference datasheet revisions to confirm compliance with current environmental standards.

Selection Notes

Select this component when a solid, non-split toroidal core is required for permanent installation on round cables. The 19 mm inner diameter dictates the maximum cable size compatibility. Consider the operating frequency range relative to the Mn-Zn material characteristics for effective attenuation.

Part Context

This part is part of the KEMET ESD-R series of solid ferrite cores. It serves as a fixed alternative to snap-on or split-core designs, offering a robust solution for applications where the cable cannot be disconnected during installation. The series provides various dimensions to accommodate different cable sizes.

Replacement Considerations

ESD-R-31C is a similar solid core within the same series but has a smaller inner diameter of 19.00 mm and different length specifications. Verify dimensional fit before substitution.
