431163951

Overview

Fair-Rite part number 431163951 is a solid free-hanging ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 31, providing an impedance of 300 Ohms at 100 MHz. The component features a circular geometry with a large inner diameter of 2.500 inches (63.50 mm) and an outer width of 2.670 inches (67.82 mm). Its height measures 0.320 inches (8.13 mm), and the inside length is 52.1 mm. This configuration allows it to accommodate thick cables or busbars without requiring clamping mechanisms.

Feature Summary

• Solid construction eliminates the need for snap-fit mechanisms or assembly tools
• Material 31 composition provides high impedance characteristics in the radio frequency range
• Free-hanging design enables simple installation over existing cable assemblies

Applications

• Electromagnetic interference suppression on heavy gauge power cables
• Noise filtering for industrial equipment busbars
• RFI mitigation in large-scale electrical distribution systems

Procurement Notes

Verify that the target cable or conductor diameter does not exceed the 2.500-inch inner diameter specification. Confirm that the application environment is compatible with standard ferrite material properties. Ensure the solid form factor is acceptable for the specific routing constraints, as this unit cannot be opened or closed around pre-existing connections.

Selection Notes

Select this component when the required cable diameter exceeds the capacity of standard snap-on cores. Material 31 is appropriate for applications requiring significant impedance in the VHF/UHF spectrum. The solid design is suitable for permanent installations where the cable can be threaded through the core during initial assembly rather than added later.

Part Context

This part belongs to the Fair-Rite solid free-hanging ferrite core category. It differs from openable clamp-on cores by its fixed geometry, which requires the cable to pass through the center bore during installation. The use of Material 31 distinguishes its magnetic performance from other materials like Material 43, which targets different frequency ranges.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
