ESD-R-47SR

Overview

The KEMET ESD-R-47SR is a solid manganese-zinc (Mn-Zn) ferrite toroid core designed for electromagnetic interference suppression. It features an inner diameter of 24.4 mm, an outer diameter of 51 mm, and an external length of 19 mm. The component operates within a temperature range of -25°C to +85°C and is rated for frequencies up to 10 MHz.

Feature Summary

• Solid Mn-Zn ferrite construction for effective high-frequency noise attenuation
• Snap-on design allows for rapid installation on existing cables without disconnection
• RoHS compliant material composition

Applications

• Electromagnetic interference suppression in consumer electronics
• Noise filtering on power and signal cables
• Common mode choke applications in industrial equipment

Procurement Notes

Verify the exact dimensional specifications against the official datasheet prior to integration, as manufacturing revisions may alter physical tolerances. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Ensure compatibility with cable diameters falling within the specified inner diameter limits to maintain optimal magnetic coupling and suppression performance.

Selection Notes

Select this component when a snap-on solution is required for retrofitting or space-constrained designs where winding a coil is impractical. The Mn-Zn material offers high permeability suitable for lower frequency noise suppression compared to Ni-Zn alternatives. Consider the thermal rating of +85°C to ensure stability under expected load conditions.
