475164281

Overview

The Fair-Rite 475164281 is a split-core ferrite assembly designed for cable EMI suppression. It utilizes 75-material composition to provide an impedance of 102 ohms at 5 MHz, with a minimum specification of 110 ohms at 5 MHz. The unit features a round snap-it design with a 6.3 mm inner diameter to accommodate cables within the specified range. Operating frequencies extend from 200 kHz to 30 MHz. The housing is constructed from polypropylene, ensuring durability and ease of installation on existing wiring without disconnection.

Feature Summary

• Split-core snap-it design allows installation on terminated cables without circuit interruption
• Utilizes 75-material composition optimized for low-frequency noise suppression
• Polypropylene housing provides structural integrity and environmental resistance

Applications

• Suppression of common-mode conducted EMI in cables
• Noise filtering in frequency ranges between 200 kHz and 30 MHz
• EMI mitigation for cables up to 6.3 mm diameter

Procurement Notes

Verify that the target cable diameter does not exceed the 6.3 mm inner diameter specification. Confirm that the application requires low-frequency suppression characteristics provided by 75-material composition rather than high-frequency alternatives. Ensure compatibility with the polypropylene housing material for the intended environmental conditions.

Selection Notes

Select this component when non-invasive installation on existing cabling is required. The 75-material composition is specifically suited for lower frequency interference scenarios compared to standard 43-material cores. The split-core form factor eliminates the need to disconnect wires during deployment, making it suitable for retrofits or maintenance applications where continuity must be maintained.
