ESD-R-16

Overview

The KEMET ESD-R-16 is a manganese zinc (MnZn) ferrite toroidal core designed for electromagnetic interference suppression. It features an outer diameter of 15.8 mm, an inner diameter of 11.6 mm, and a height of 8.4 mm. The component operates within a temperature range of -25°C to +85°C and exhibits an impedance of 100 MHz at its rated frequency.

Feature Summary

• Snap-on design allows for rapid installation onto existing cables without disconnection.
• High permeability manganese zinc material provides effective noise attenuation in the high-frequency spectrum.
• RoHS compliant construction ensures adherence to environmental safety standards.

Applications

• Consumer electronics cable shielding
• Data line noise suppression
• Power cord EMI reduction

Procurement Notes

Verify the specific MnZn material grade and impedance characteristics against your target frequency requirements. Confirm that the 11.6 mm aperture accommodates the cable assembly diameter with sufficient clearance. Ensure the operating temperature range meets your environmental conditions.

Selection Notes

Select this model when a snap-on solution is preferred over split cores for ease of retrofitting. Consider the MnZn composition for lower frequency noise compared to NiZn alternatives. Verify physical dimensions against the cable bundle size to ensure proper fit and magnetic coupling efficiency.

Part Context

This component belongs to the ESD-R series of ferrite rings manufactured by KEMET. These toroidal cores are engineered for broadband noise suppression applications. The series utilizes manganese zinc ferrite materials optimized for common mode choke performance in compact form factors.

Replacement Considerations

Consult official KEMET documentation for direct cross-references. Generic substitutes may differ in impedance curves or material permeability. Verify dimensional compatibility before replacing.
