ESD-R-47SR-P

Overview

The KEMET ESD-R-47SR-P is a manganese-zinc (Mn-Zn) ferrite toroidal core designed for electromagnetic interference suppression. It features an outer diameter of 48.5 mm, an inner diameter of 26 mm, and an external length of 16 mm. The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 150 kHz.

Feature Summary

• Utilizes Mn-Zn ferrite material for effective high-frequency noise attenuation
• Toroidal geometry provides efficient magnetic flux containment
• Engineered for robust performance in EMI suppression applications

Applications

• Electromagnetic interference filtering in electronic circuits
• Common mode choke core assembly for cable harnesses
• Power supply line noise suppression components

Procurement Notes

Verify the specific suffix 'P' against official KEMET documentation to confirm packaging or variant distinctions. Ensure dimensional tolerances align with mechanical constraints. Confirm RoHS compliance status through current datasheets before integration into regulated assemblies.

Selection Notes

Select this core based on required inner diameter clearance for cable bundles and outer diameter space availability. Evaluate Mn-Zn material suitability for the target frequency spectrum. Verify thermal stability requirements against the specified operating temperature limits.
