ESD-R-31C

Overview

The KEMET ESD-R-31C is a solid Ni-Zn toroidal ferrite core designed for electromagnetic interference (EMI) suppression. It features a free-hanging installation type with an inner diameter of 19.00 mm, an outer diameter of 31.00 mm, and a length of 8.00 mm. The component operates within a temperature range of -25°C to +85°C and complies with RoHS standards.

Feature Summary

• Solid toroidal construction for stable magnetic properties
• Ni-Zn material composition optimized for high-frequency noise attenuation
• Free-hanging design facilitates easy cable integration

Applications

• Electromagnetic interference suppression on cables
• Signal filtering in electronic assemblies
• Noise reduction in consumer electronics

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as ESD-R-31C-1 exist with different dimensional tolerances. Confirm that the required inner diameter matches the 19.00 mm specification for your cable bundle. Ensure compliance with RoHS requirements if applicable to your manufacturing process.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. The 19.00 mm inner diameter accommodates specific cable bundles that do not fit smaller cores. Consider the Ni-Zn material characteristics for the target frequency range of interference suppression.

Part Context

This part belongs to the KEMET ESD-R series of commercial-grade EMI cores. The series includes various sizes and materials to address different noise suppression needs. The ESD-R-31C represents a standard size option within this lineup for general-purpose applications.

Replacement Considerations

Check for ESD-R-31C-1 if slight dimensional variations are acceptable. Verify compatibility with other solid toroidal cores from different manufacturers by comparing inner and outer diameters.
