443800506

Overview

The Fair-Rite Products Corp. part number 443800506 is a split core ferrite bead designed for cable applications. It features an internal diameter of 12.8 mm (0.520 inches) and an outer dimension of 29.69 mm x 12.70 mm. The component provides an impedance of 56 ohms at frequencies between 25 MHz and 300 MHz, or 75 ohms at 100 MHz depending on the specific material characterization referenced in distributor data. It utilizes a hinged snap-on design for free-hanging installation around round cables.

Feature Summary

• Split core construction with hinged snap-on mechanism for easy installation without disconnecting cables
• Designed for suppression of electromagnetic interference on round cables
• Controlled impedance characteristics across specified frequency ranges

Applications

• Cable ferrite clamping for EMI suppression
• Round cable assembly integration
• Electromagnetic interference filtering in electronic systems

Procurement Notes

Verify the exact impedance specification required for your application, as sources cite both 56 ohms and 75 ohms values. Confirm that the 12.8 mm inner diameter accommodates the target cable size. Ensure compliance with RoHS directives if applicable to your manufacturing process. Check lead times as they may vary significantly by supplier.

Selection Notes

Select this component when a non-invasive ferrite solution is needed for existing cable assemblies. The split core design allows for retrofitting without cutting wires. Ensure the cable diameter fits within the 12.8 mm internal clearance. Consider the operating frequency range to match the ferrite material's impedance profile against the noise spectrum being suppressed.

Part Context

This part belongs to Fair-Rite's Round Cable Snap-It series, which are controlled for impedance rather than absolute material permeability alone. These components are engineered for consistent performance in suppressing common mode noise on power and signal cables. The split core format distinguishes it from solid toroidal beads used during initial manufacturing.

Replacement Considerations

Direct substitutes must match the 12.8 mm inner diameter and snap-on mechanical form factor. Verify impedance curves at critical frequencies, as variations exist between 56 ohm and 75 ohm ratings in available documentation. Ensure the replacement maintains the same environmental compliance standards.
