ESD-R-12F

Overview

The KEMET ESD-R-12F is a nickel-zinc toroidal ferrite core designed for electromagnetic interference suppression. It features an inner diameter of 8.5 mm, an outer diameter of 12 mm, and a height of 15 mm. The component operates at a maximum temperature of +85°C and is intended for use in consumer electronics applications.

Feature Summary

• Snap-on toroidal design for rapid installation on cables
• Nickel-zinc material composition for high-frequency noise attenuation

Applications

• Consumer electronics cable shielding
• Electromagnetic interference suppression

Procurement Notes

Verify the specific datasheet version to confirm impedance characteristics at target frequencies, as values may vary by batch or revision. Ensure the supplier provides documentation confirming compliance with RoHS standards. Cross-reference the part number against official KEMET catalogs to validate current production status and availability before finalizing procurement orders.

Selection Notes

Select this component when a snap-on solution is required for cables fitting within the 8.5 mm aperture. The nickel-zinc formulation is suitable for higher frequency ranges compared to manganese-zinc alternatives. Confirm that the operating environment remains below the +85°C maximum temperature rating to ensure material stability and performance consistency.

Part Context

This component belongs to the ESD-R series of snap-on ferrite cores manufactured by KEMET. These cores are engineered to suppress common-mode noise on data and power lines without requiring soldering or complex mounting hardware, providing a flexible retrofit option for existing cable assemblies in electronic devices.

Replacement Considerations

Direct substitutes include other KEMET ESD-R series parts with matching dimensions, such as ESD-R-12M-H, provided the impedance profile meets the specific application requirements.
