ESD-R-47S

Overview

The KEMET ESD-R-47S is a manganese-zinc (Mn-Zn) ferrite toroid designed for electromagnetic interference suppression. It features an outer diameter of 47 mm, an inner diameter of 27 mm, and an external length of 15 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

• Utilizes Mn-Zn ferrite material for effective high-frequency noise attenuation
• Bare core design allows for custom winding configurations
• Robust construction suitable for demanding industrial environments

Applications

• Common mode choke cores for power line filtering
• Differential mode inductors in switching power supplies
• EMI suppression components in industrial control systems

Procurement Notes

Verify the specific datasheet revision and physical dimensions against current manufacturing standards before integration. Confirm that the bare core format aligns with your winding capabilities and assembly processes. Ensure thermal ratings are sufficient for the intended operating environment.

Selection Notes

Select this component when custom inductance values are required through variable turn counts. The Mn-Zn composition offers high permeability for compact magnetic circuit designs. Evaluate the specific frequency spectrum of the noise to ensure optimal attenuation characteristics at 10 MHz.

Part Context

This part belongs to the ESD-R-SRH series of ferrite rings from KEMET. It serves as a passive magnetic component used to suppress electromagnetic interference in electronic circuits by providing impedance to unwanted high-frequency signals.
