ESD-SR-160

Overview

The KEMET ESD-SR-160 is a snap-on ferrite core designed for round cables, belonging to the ESD-SR series. Constructed from Ni-Zn material, it features a 9 mm internal diameter and external dimensions of 20.2 mm x 20 mm x 39 mm. The component provides an impedance of 145 Ω at 25 MHz and 246 Ω at 100 MHz. It operates within a temperature range of -40°C to +85°C and supports frequencies up to 300 MHz. The design allows for free-hanging installation without requiring tools.

Feature Summary

• Snap-on design enables rapid installation on round cables without disassembly
• Ni-Zn ferrite material ensures high stability and reliability for EMI suppression
• Tool-free operation facilitates quick deployment in assembly processes

Applications

• Electromagnetic interference suppression in consumer electronics
• Cable noise reduction in electronic equipment wiring
• High-frequency signal integrity management in round cable assemblies

Procurement Notes

Verify the specific part number ESD-SR-160 against official KEMET documentation to confirm dimensional accuracy and impedance characteristics. Ensure the selected component matches the required cable diameter of 9 mm and operating temperature range. Cross-reference datasheet specifications for RoHS compliance and material composition before finalizing procurement decisions.

Selection Notes

Select this component when a tool-free, snap-on ferrite solution is required for round cables with diameters up to 9 mm. Consider the Ni-Zn material properties for applications involving frequencies up to 300 MHz. Evaluate the physical dimensions (20.2 mm x 20 mm x 39 mm) to ensure adequate space for installation in the target electronic enclosure or cable harness layout.

Part Context

The ESD-SR-160 is part of KEMET's ESD-SR Snap-on Cores series, specifically engineered for easy integration into cable assemblies. This series focuses on providing reliable electromagnetic interference suppression through simple mechanical attachment methods, distinguishing itself from split-core designs that may require additional fastening mechanisms.

Replacement Considerations

The ESD-SR-160H is a hinged variant within the same family, offering similar electrical characteristics but with a different mechanical opening mechanism. Verify dimensional compatibility and impedance curves when considering alternative snap-on cores from other manufacturers.
