ESD-R-10S

Overview

The KEMET ESD-R-10S is a Ni-Zn ferrite toroid core designed for electromagnetic interference suppression. It features an outer diameter of 10.5 mm, an inner diameter of 5.5 mm, and a height of 20.0 mm. The component provides an impedance of 110 Ω at 100 MHz and 55 Ω at 25 MHz. It is constructed from bare ferrite material suitable for snap-on installation applications.

Feature Summary

• Snap-on design allows for rapid installation onto existing cables without cutting or splicing
• Ni-Zn ferrite composition optimized for high-frequency noise attenuation
• Bare ferrite construction ensures compatibility with various cable jacket materials

Applications

• Electromagnetic interference (EMI) suppression on data and power cables
• Common mode noise reduction in consumer electronics assemblies
• Signal integrity enhancement in high-speed digital interfaces

Procurement Notes

Verify the specific impedance requirements against the application frequency spectrum before procurement. Confirm that the cable outer diameter falls within the 5.5 mm to 10.5 mm range to ensure proper mechanical fit. Check for RoHS compliance status if required by the end-product regulations. Ensure the bare ferrite material is compatible with the operating environment temperature.

Selection Notes

Select this component when a non-invasive solution for cable noise suppression is required. The snap-on form factor eliminates the need for additional hardware or tools during assembly. Consider the impedance profile at the target noise frequency rather than just the maximum rating. Evaluate the physical space constraints around the cable to accommodate the 20.0 mm height dimension.

Part Context

This part belongs to the ESD-R series of snap-on ferrite cores manufactured by KEMET. These components are engineered for easy integration into wiring harnesses and PCB cable exits. The series offers various dimensions to suit different cable sizes while maintaining consistent magnetic properties for effective broadband noise filtering.

Replacement Considerations

Substitute parts must match the 10.5 mm OD, 5.5 mm ID, and 20.0 mm height dimensions. Verify that alternative Ni-Zn ferrites provide comparable impedance characteristics at 25 MHz and 100 MHz. Ensure the replacement maintains the snap-fit mechanical retention capability.
