ESD-R-38-1

Overview

The KEMET ESD-R-38-1 is a solid Mn-Zn ferrite toroidal core designed for round cables. It features an outer diameter of 39.0 ±1.0 mm, an inner diameter of 17.5 ±1.0 mm, and a height of 14.0 ±1.0 mm. The component operates at frequencies up to 300 MHz and is supplied in case and tape packaging.

Feature Summary

• Solid toroidal design for secure cable clamping
• Mn-Zn ferrite material for broadband suppression
• Snap-on installation without disconnection

Applications

• Electromagnetic interference suppression on round cables
• Electrostatic discharge protection circuits
• High-frequency noise filtering in electronic assemblies

Procurement Notes

Verify the specific ordering suffix against official KEMET documentation to confirm physical dimensions and packaging type. Ensure the selected variant matches the required cable diameter and frequency range. Confirm compliance status with current regulatory standards before integration into final designs.

Selection Notes

Select this component based on the required inner diameter for the target cable size. Evaluate the Mn-Zn material properties for the specific frequency spectrum of the noise to be suppressed. Consider the snap-on mechanical fit for assembly efficiency and space constraints within the enclosure.

Part Context

This part belongs to the KEMET ESD-R series of solid ferrite cores. These components are engineered for low and high-frequency applications, providing effective common-mode noise attenuation. The series offers various sizes to accommodate different cable diameters and impedance requirements.

Replacement Considerations

Consult official KEMET substitution guides for equivalent parts. Verify that any alternative maintains the same inner diameter and material characteristics to ensure consistent performance.
