ESD-R-10D

Overview

The KEMET ESD-R-10D is a solid toroidal ferrite core designed for electromagnetic interference suppression. It features an inner diameter of 5 mm and an outer diameter of 9.5 mm, with a height of 10 mm. The component operates within a temperature range of -25 °C to +85 °C and is rated for frequencies up to 300 MHz. Constructed from manganese zinc (MnZn) material, it provides effective noise filtering for round cables in electronic circuits.

Feature Summary

• Solid toroidal geometry optimized for round cable applications
• Manganese zinc (MnZn) composition for high-frequency attenuation
• Flame resistant case construction meeting UL94V-2 standards

Applications

• Electromagnetic interference suppression on round cables
• Common mode noise filtering in consumer electronics
• Signal integrity enhancement in high-frequency circuits

Procurement Notes

Verify the specific MnZn formulation matches your target frequency spectrum, as performance varies by material grade. Confirm that the ambient operating environment remains within the specified -25 °C to +85 °C range to ensure stable magnetic properties. Ensure the cable diameter fits securely within the 5 mm inner diameter to maintain consistent coupling and suppression effectiveness during installation.

Selection Notes

Select this core when suppressing common mode noise on round conductors at frequencies approaching 300 MHz. The 5 mm inner diameter restricts usage to cables of corresponding size. Consider the thermal limits of -25 °C to +85 °C for environmental compatibility. The solid toroidal design offers superior mechanical stability compared to split cores for permanent installations.

Part Context

This component belongs to the KEMET ESD-R series of ferrite cores, which are engineered for general-purpose electromagnetic interference suppression. The series utilizes various manganese zinc and nickel zinc materials to address different frequency requirements. These cores are widely integrated into consumer electronics and industrial equipment to mitigate radiated emissions and improve signal quality.

Replacement Considerations

Direct substitutes must match the 5 mm inner diameter, 9.5 mm outer diameter, and 10 mm height dimensions. Verify equivalent MnZn material characteristics for similar impedance profiles at 300 MHz. Alternative suppliers may offer compatible toroidal cores if dimensional and material specifications align precisely with the original design constraints.
