431164051

Overview

Fair-Rite part number 431164051 is a snap-open ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing an impedance of 290 ohms at 100 MHz and 138 ohms at 25 MHz. The component features a split design with one opening, allowing installation over existing cables without disconnection. Physical dimensions include an inner diameter of 65.28 mm (2.570 inches), an outer width of 80.77 mm (3.180 inches), an outer height of 8.13 mm (0.320 inches), and a length of 32.31 mm (1.272 inches).

Feature Summary

• Snap-open construction enables installation on terminated cables.
• Material 43 composition provides high impedance in the VHF/UHF range.
• Free-hanging design allows flexible mounting configurations.

Applications

• Electromagnetic interference suppression on large cables.
• High-frequency noise filtering in electronic assemblies.
• Retroactive cable treatment for compliance testing.

Procurement Notes

Verify the specific material grade and impedance values against the manufacturer's current datasheet before integration. Confirm that the physical aperture dimensions accommodate the target cable bundle size to ensure proper magnetic coupling and mechanical fit.

Selection Notes

Select this component when retrofitting ferrite suppression onto cables that cannot be disconnected. Material 43 is appropriate for applications requiring significant attenuation in the very high frequency spectrum. Ensure the openable mechanism remains secure during operation.

Part Context

This component belongs to the Fair-Rite Snap-It series of split ferrite cores. These cores are distinct from solid toroids by their ability to enclose cables post-assembly. They are widely used in industrial and commercial electronics for managing conducted emissions.
