461164951

Overview

The Fair-Rite Products Corp. part number 461164951 is a split-core ferrite assembly designed for electromagnetic interference suppression on round cables. It utilizes Ferrite Material 61 and features an internal diameter accommodating cable diameters ranging from 2.5 mm to 25.4 mm. The component provides a minimum impedance of 800 ohms at 200 MHz, with operational frequency characteristics extending up to 1 GHz. This Snap-It™ design allows for easy installation onto existing wiring without disconnection.

Feature Summary

• Split-core snap-bead design enables rapid installation onto existing cables without wire termination removal
• Utilizes Ferrite Material 61 optimized for high-frequency noise absorption in the VHF/UHF spectrum
• Accommodates a wide range of round cable and bundled wire diameters within specified limits

Applications

• Suppression of electromagnetic interference on round cables and bundled wires
• High-frequency noise filtering in communication equipment cabling
• EMI mitigation in electronic assemblies requiring non-invasive retrofitting

Procurement Notes

Verify that the target cable diameter falls strictly within the 2.5 mm to 25.4 mm range to ensure proper fit and magnetic coupling. Confirm that the application requires the specific impedance profile of Material 61, as other materials offer different frequency responses. Check for RoHS compliance requirements if applicable to the end product regulations.

Selection Notes

Select this component when non-invasive installation is required for round cables or wire bundles. Material 61 is appropriate for applications targeting higher frequency noise suppression compared to standard Materials 31 or 43. Ensure the physical space allows for the external dimensions of the snap bead and that the cable diameter does not exceed the maximum opening capacity.

Part Context

This part belongs to the Fair-Rite Snap-It™ series of split-core ferrites. These components are engineered for convenience in field installations where traditional slide-on beads cannot be used due to fixed connectors. The series offers various material compositions and sizes to match specific impedance and cable diameter requirements across diverse electronic environments.

Replacement Considerations

Direct replacements must match the 2.5–25.4 mm cable diameter range and provide comparable impedance at 200 MHz. Alternative Fair-Rite parts using Material 61 may be considered if dimensional constraints differ. Verify that any substitute maintains the split-core functionality for retrofit applications.
