446176451

Overview

Fair-Rite part number 446176451 is a split-core ferrite assembly designed for electromagnetic interference suppression. It utilizes Material 46, providing an impedance of 416 ohms at 25 MHz and 300 MHz. The unit features a round cable core design with an internal diameter of 18 mm, accommodating cables ranging from 2.5 mm to 25.4 mm in diameter. Physical dimensions include a length of 38.6 mm and a height of 38.3 mm.

Feature Summary

• Split-core snap-it design allows installation on existing cables without disconnection
• Material 46 composition provides high impedance characteristics for EMI suppression
• Round geometry accommodates bundled wires and various cable diameters

Applications

• Electromagnetic interference suppression components
• Cable and wiring noise reduction
• Bundled wire protection

Procurement Notes

Verify the specific impedance values and material designation against the official Fair-Rite datasheet before integration. Confirm that the 18 mm inner diameter matches the target cable bundle size. Ensure the split-core mechanism integrity is maintained during handling to preserve magnetic circuit continuity.

Selection Notes

Select this component when retrofitting EMI suppression onto installed cabling is required. The split-core architecture eliminates the need to disconnect wires. Material 46 is suitable for applications requiring significant attenuation at 25 MHz and 300 MHz frequencies.
