ESD-R-12C

Overview

The KEMET ESD-R-12C is a nickel-zinc ferrite toroidal core designed for electromagnetic interference suppression. It features an internal diameter of 7.3 mm and an external diameter of 11.8 mm, with a length of 15 mm. The component operates up to 300 MHz and has a maximum operating temperature of +85°C. It is RoHS compliant and packaged in bulk.

Feature Summary

• Constructed from nickel-zinc ferrite material for effective high-frequency noise attenuation
• Snap-on toroidal design allows for easy installation on cables without disconnection
• RoHS compliant construction suitable for environmentally conscious manufacturing

Applications

• Electromagnetic interference suppression on data and power cables
• Common mode noise reduction in electronic assemblies
• ESD protection components in consumer electronics

Procurement Notes

Verify current availability status as the component may be subject to obsolescence notices. Confirm specific packaging quantities and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure compliance with regional regulatory requirements for electronic components.

Selection Notes

Select this component when a 7.3 mm inner diameter fits the target cable bundle. Verify that the nickel-zinc material characteristics align with the specific frequency range of the noise spectrum being suppressed. Ensure the operating environment remains within the specified thermal limits.

Part Context

This part belongs to the ESD-R series of snap-on ferrite cores manufactured by KEMET. These cores are engineered for rapid assembly onto existing wiring harnesses. The series provides standardized dimensions to accommodate various cable sizes while maintaining consistent impedance characteristics across different frequencies.

Replacement Considerations

The ESD-R-12C-2 is a documented variant within the same product family. Verify dimensional compatibility and material specifications before substitution. No other direct cross-references are confirmed in public documentation.
