ESD-R-12S

Overview

The KEMET ESD-R-12S is a nickel-zinc ferrite toroidal core designed for general electronics applications. It features an outer diameter of 12 mm, an inner diameter of 7 mm, and a height of 5.5 mm. The component operates within standard electronic environments and complies with RoHS standards.

Feature Summary

• Snap-on toroidal design for rapid installation on cables
• Nickel-zinc material composition for high-frequency noise suppression
• Solid ring structure providing consistent magnetic properties

Applications

• General electronics cable noise suppression
• Consumer equipment signal integrity enhancement
• Industrial control wiring interference reduction

Procurement Notes

Verify the specific suffix 'S' to confirm the snap-on variant rather than solid or split types. Ensure the 7mm inner diameter matches the target cable bundle size. Confirm RoHS compliance status if required by local regulations. Check datasheet for impedance characteristics at relevant frequencies.

Selection Notes

Select this component when a snap-on installation method is preferred over adhesive or clip styles. The 7mm aperture accommodates moderate cable diameters. Nickel-zinc material is suitable for higher frequency ranges compared to manganese-zinc alternatives. Verify mechanical fit before integration into tight spaces.

Part Context

This part belongs to the KEMET ESD-R series of ferrite cores. The series includes various sizes and materials tailored for different cable diameters and frequency requirements. The ESD-R designation indicates a solid toroidal shape, while the 'S' suffix typically denotes a snap-on configuration for ease of assembly.

Replacement Considerations

Direct substitutes include other KEMET snap-on ferrites with identical 7mm inner diameter and similar nickel-zinc material properties. Cross-reference dimensions carefully as outer diameters may vary between manufacturers. Ensure equivalent impedance performance at the target operating frequency.
