• Utilizes Nickel Zinc material composition optimized for radio-frequency noise suppression

Applications

• Suppression of common-mode noise on data and power cables
• EMI filtering in consumer electronics assemblies
• Radio-frequency interference mitigation in communication interfaces

Procurement Notes

Verify the specific Nickel Zinc material grade and dimensional tolerances against the official KEMET datasheet before integration. Confirm that the 7.3 mm inner diameter accommodates the target cable bundle without excessive mechanical stress. Ensure the application environment remains within the specified +85°C thermal limit to maintain magnetic performance integrity.

Selection Notes

Select this component when a compact 7.3 mm toroid is required for high-frequency noise reduction. The Nickel Zinc formulation is suitable for frequencies up to 300 MHz. Evaluate cable thickness compatibility with the aperture size prior to procurement to ensure proper fit and effective magnetic coupling.

Part Context

This part belongs to the KEMET ESD-R series of ferrite toroids, which are passive components used for EMI suppression. The series offers various sizes and materials to address different cable diameters and frequency requirements in electronic design.

Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitutes. Ensure any alternative maintains the 7.3 mm inner diameter and compatible Nickel Zinc magnetic properties.
