ESD-R-47H

Overview

The KEMET ESD-R-47H is a manganese-zinc (Mn-Zn) ferrite toroidal core designed for electromagnetic interference suppression. It features an outer diameter of 52.5 mm, an inner diameter of 22.7 mm, and an external length of 18.5 mm. The component is supplied with a protective case and operates within a temperature range of -25°C to +85°C. It is rated for frequencies up to 10 MHz and complies with RoHS standards.

Feature Summary

• Constructed from manganese-zinc ferrite material for effective high-frequency noise attenuation
• Includes an integrated protective case to secure the core during installation
• Solid toroidal geometry provides consistent magnetic properties for cable filtering

Applications

• Electromagnetic interference suppression on round cables
• Common mode choke applications in electronic assemblies
• Noise reduction in power supply input lines

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm physical dimensions and material composition. Ensure the selected variant includes the required case configuration if mechanical protection is necessary for the assembly environment. Cross-reference the frequency rating with the application spectrum to validate performance requirements.

Selection Notes

Select this component based on the required cable inner diameter fitting within the 22.7 mm bore size. Evaluate the thermal environment to ensure operation remains within the specified -25°C to +85°C range. Confirm that the Mn-Zn material characteristics align with the target frequency band for optimal impedance performance.

Part Context

This part belongs to the ESD-R series of ferrite toroids manufactured by KEMET. These components are engineered for general-purpose EMI suppression tasks. The series offers various sizes and materials to accommodate different cable diameters and frequency requirements across industrial and consumer electronics.

Replacement Considerations

Consult official substitution lists for compatible Mn-Zn toroids with matching dimensions. Verify that alternative parts maintain the same operating temperature range and include similar casing provisions if required.
