ESD-SR-110

Overview

The KEMET ESD-SR-110 is a snap-on ferrite core designed for round cables, belonging to the ESD-SR Snap-on Cores series. It features an internal diameter of 5 mm and measures 14.4 mm in width, 14.2 mm in height, and 28 mm in depth. The component provides an impedance of 175 Ω at 25 MHz and 320 Ω at 100 MHz. Constructed from Ni-Zn ferrite material with a permeability grade of 65C, it operates within a temperature range up to 125 °C. The unit is RoHS compliant and polarized-free, suitable for EMI suppression in consumer electronics.

Feature Summary

• Snap-on design allows for rapid installation on existing round cables without disconnection
• Ni-Zn ferrite composition provides high impedance characteristics for effective EMI suppression
• Openable structure facilitates retrofitting onto terminated cable assemblies

Applications

• Consumer electronics cable shielding
• EMI suppression on signal and power lines
• ESD protection for data transmission cables

Procurement Notes

Verify the specific impedance requirements against application frequencies, noting the 175 Ω value at 25 MHz and 320 Ω at 100 MHz. Confirm that the 5 mm inner diameter accommodates the target cable bundle size. Ensure compliance with RoHS standards if required by the end product regulations. Check for any specific automotive or industrial certifications if the deployment environment demands higher reliability than standard consumer grades.

Selection Notes

Select this component when retrofitting EMI suppression onto round cables where space constraints prevent through-hole mounting. The 5 mm aperture limits usage to smaller cable bundles. Compare impedance curves against noise frequency spectra to ensure adequate attenuation at target frequencies. Consider the snap-on mechanism for assembly speed advantages over split cores requiring tools.

Part Context

The ESD-SR-110 is part of KEMET's ESD-SR series of snap-on ferrite cores. This series focuses on providing easy-to-install solutions for electromagnetic interference reduction in various electronic assemblies. The components are engineered for compatibility with standard round cabling found in consumer and industrial applications.

Replacement Considerations

Direct substitutes must match the 5 mm inner diameter and similar impedance profiles at 25 MHz and 100 MHz. Verify physical dimensions (14.4 x 14.2 x 28 mm) for spatial fit. Alternative materials like Mn-Zn may offer different frequency characteristics but require re-validation of EMI performance.
