ESD-R-57D-1

Overview

The KEMET ESD-R-57D-1 is a solid nickel-zinc (NiZn) ferrite core designed for electromagnetic interference suppression. It features a circular geometry with an inner diameter of 32.4 mm, an outer diameter of 61 mm, and a length of 24 mm. The component operates within a temperature range of -25°C to +85°C and supports frequencies up to 300 MHz. It is compliant with RoHS3 standards and is classified as a cable ferrite suitable for free-hanging installation.

Feature Summary

• Constructed from nickel-zinc material for high-frequency noise attenuation
• Solid design intended for free-hanging cable mounting
• Capable of suppressing electromagnetic interference at frequencies up to 300 MHz

Applications

• Consumer electronics cable shielding
• General electromagnetic interference suppression
• Cable noise reduction in electronic assemblies

Procurement Notes

Verify the specific suffix designation against official documentation to confirm material composition and dimensional tolerances. Ensure that the selected variant matches the required operating temperature range and frequency characteristics for the target application environment.

Selection Notes

Select this component when a solid NiZn ferrite core is required for cables fitting within a 32.4 mm inner diameter. Consider the 300 MHz frequency limit and the -25°C to +85°C operational range during system design to ensure compatibility with environmental conditions.

Part Context

This part belongs to the KEMET ESD-R series of solid ferrite cores. The series offers various dimensions and materials, including manganese-zinc and nickel-zinc options, to address different electromagnetic interference challenges across industrial and consumer applications.

Replacement Considerations

ESD-R-57A-1 shares similar physical dimensions but utilizes manganese-zinc material instead of nickel-zinc, altering its magnetic properties.
