446164251

Overview

The Fair-Rite 446164251 is a split-core ferrite clamp designed for electromagnetic interference suppression. It utilizes Material 46, providing an impedance of 245 ohms at 100 MHz. The component features a round cable aperture with a maximum diameter of 6.3 mm. It operates effectively within a frequency range from 25 MHz to 300 MHz. The core assembly allows for installation on existing cables without disconnection.

Feature Summary

• Split-core design enables clamping onto pre-existing cables
• Material 46 composition provides high-frequency noise attenuation
• Round cross-section accommodates standard wire bundles

Applications

• Electromagnetic interference suppression in broadband frequencies
• Noise reduction on data and power cables
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific material designation (Material 46) and impedance characteristics against your schematic requirements. Confirm that the 6.3 mm inner diameter adequately fits the target cable bundle. Ensure compliance with RoHS standards if required by your manufacturing process. Cross-reference the part number with official Fair-Rite documentation to confirm current availability and lead times.

Selection Notes

Select this component when retrofitting ferrite suppression onto installed cabling is necessary. The split-core mechanism eliminates the need to disconnect wires during assembly. Material 46 is suitable for applications requiring significant attenuation in the VHF/UHF spectrum. Ensure the cable diameter does not exceed the 6.3 mm limit to maintain proper magnetic coupling.

Part Context

This component belongs to the Fair-Rite snap-it series of ferrite cores. These are distinct from solid toroidal or EP cores due to their hinged construction. They are primarily used for post-assembly EMI mitigation rather than as components within transformer windings.

Replacement Considerations
