443166651

Overview

Fair-Rite part number 443166651 is a split-core ferrite assembly designed for flat cable applications. It utilizes Fair-Rite Material 43, providing an impedance of 290 ohms at 25 MHz and operating effectively from 1 MHz to 300 MHz. The physical dimensions are 33.7 mm in length and 1.3 mm in height. This Snap-It™ component allows for installation on existing multi-conductor flat cables without disconnection.

Feature Summary

• Split-core design enables installation on terminated flat cables
• Material 43 composition provides high impedance in the 25 MHz to 300 MHz range
• Snap-It mechanism secures the core around the cable

Applications

• Suppression of common-mode conducted EMI on multi-conductor flat cables
• EMI mitigation in data transmission lines
• Noise reduction in industrial control cabling

Procurement Notes

Verify the specific material grade and impedance tolerance against the manufacturer's current datasheet before integration. Confirm that the flat cable thickness falls within the mechanical clearance limits of the 1.3 mm height specification. Ensure compatibility with the intended frequency spectrum requirements.

Selection Notes

Select this component when retrofitting EMI suppression onto existing flat ribbon cables is required. Material 43 is suitable for frequencies above 10 MHz. Verify that the cable width fits within the internal aperture of the snap-core assembly to ensure proper magnetic coupling and effective noise attenuation.

Part Context

This component belongs to the Fair-Rite Snap-It series of split-core ferrites. These assemblies are engineered specifically for flat cables, offering a convenient alternative to solid cores that require cable termination removal. They are widely used in electronics manufacturing for post-assembly noise filtering.
