ESD-SR-100

Overview

The KEMET ESD-SR-100 is a snap-on ferrite core designed for electromagnetic interference suppression. It features a Ni-Zn ferrite material composition and an inner diameter of 9 mm. The component exhibits an impedance of 30 Ω at 25 MHz and 80 Ω at 100 MHz. Its physical dimensions are 9 mm in inner diameter, 20.2 mm in outer diameter, and 39 mm in length. It operates within a temperature range up to +85 °C.

Feature Summary

• Snap-on installation design for rapid deployment on round cables
• Ni-Zn ferrite material construction for effective high-frequency noise attenuation
• ESD-SR series classification indicating electrostatic discharge protection capabilities

Applications

• Electromagnetic interference suppression on round cables
• Electrostatic discharge protection in electronic assemblies
• Noise filtering in consumer electronics wiring

Procurement Notes

Verify the specific impedance requirements against application frequencies, as values vary between 25 MHz and 100 MHz. Confirm that the cable diameter fits within the 9 mm inner diameter specification. Ensure the operating environment remains below the maximum temperature rating of +85 °C. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a snap-on solution is preferred over split-core or clamp types for speed of assembly. Choose based on the required impedance profile at target noise frequencies. Ensure the physical size accommodates the cable bundle. Consider the Ni-Zn material properties for the specific frequency band of interest.

Part Context

This part belongs to the KEMET ESD-SR Snap-on Cores series, which specializes in ferrite cores for ESD protection. The series includes various sizes and materials tailored for different cable diameters and frequency ranges. These components are distinct from toroidal cores or clip-on types, offering a unique snap-fit mechanical interface.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing cable diameters and impedance curves before considering alternative suppliers.
