ESD-SR-100G

Overview

The KEMET ESD-SR-100G is a snap-on ferrite core designed for electromagnetic interference (EMI) suppression. It features a nickel-zinc material composition and accommodates cables with a maximum diameter of 6 mm. The component measures 16.5 mm in width, 21 mm in depth, and has an internal bore of 6 mm. It provides an impedance of 80 Ω at 100 MHz and reaches 300 Ω at 300 MHz. The unit operates within a temperature range of -25°C to +85°C and complies with RoHS standards.

Feature Summary

• Snap-on design allows for rapid installation on existing cable assemblies without disconnection.
• Nickel-zinc ferrite material provides effective high-frequency noise attenuation.
• Free-hanging mounting style offers flexible integration into various electronic enclosures.

Applications

• Suppression of electromagnetic interference in consumer electronics
• Noise filtering on data and power cables in industrial equipment
• Common mode choke applications for signal integrity protection

Procurement Notes

Verify the specific suffix 'G' against official KEMET documentation to confirm compliance details and material specifications. Ensure the selected part matches the required cable diameter of 6 mm for proper fit. Cross-reference the impedance values at 100 MHz and 300 MHz with system requirements. Confirm RoHS status through current manufacturer declarations before procurement.

Selection Notes

Select this component when a split-core solution is required for retrofitting or testing environments where permanent attachment is not feasible. The 6 mm inner diameter limits usage to smaller gauge wires. Compare impedance characteristics against other series members if higher frequency performance or different cable sizes are needed. Ensure the operating temperature range meets the environmental conditions of the target application.

Part Context

This component belongs to the ESD-SR Snap-on Cores series from KEMET. This family focuses on easy-installation ferrite solutions for EMI suppression. The series includes various sizes and materials to address different cable diameters and frequency ranges. These cores are distinct from toroidal rings as they feature a split design for quick assembly.

Replacement Considerations

Direct substitutes include other KEMET ESD-SR series parts with matching 6 mm bore dimensions. Verify that alternative models maintain similar impedance profiles at critical frequencies. Ensure replacement units support the same free-hanging mounting method and temperature ratings.
