ESD-R-47M-H

Overview

The KEMET ESD-R-47M-H is a solid manganese-zinc (Mn-Zn) ferrite toroidal core designed for electromagnetic interference suppression on round cables. It features an outer diameter of 51 mm, an inner diameter of 24.4 mm, and an external length of 19 mm. The component operates within a temperature range of -55°C to +125°C and provides an impedance of 31 ohms at 10 MHz.

Feature Summary

• Solid cylindrical construction for secure cable mounting
• Manganese-zinc material composition for high-frequency attenuation
• Rated for continuous DC currents up to 4000 milliamps

Applications

• Suppression of electromagnetic interference on round power cables
• Common mode noise reduction in electronic equipment wiring
• Signal integrity enhancement in high-frequency data transmission lines

Procurement Notes

Verify the specific suffix 'H' against official KEMET documentation to confirm the maximum operating temperature rating of 125°C. Ensure the physical dimensions match the required cable clearance. Confirm RoHS compliance status through the current manufacturer datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a robust, solid-core solution is required for cables with diameters near 24.4 mm. The Mn-Zn material offers effective attenuation at 10 MHz compared to other materials. Consider the 31-ohm impedance value relative to the target noise frequency spectrum to ensure adequate suppression performance.

Part Context

This part belongs to the KEMET ESD-R series of cable ferrites. These components are engineered for EMI suppression in various electronic assemblies. The series utilizes Mn-Zn ferrite materials optimized for broadband noise reduction across common industrial and consumer applications.

Replacement Considerations

Cross-reference with KEMET ESD-R-47SRH for similar dimensional constraints but verify distinct temperature ratings. Check ESD-R-47-1 for comparable size while noting potential differences in packaging and thermal limits.
