2643006302

Overview

The Fair-Rite 2643006302 is a solid free-hanging ferrite EMI suppression bead constructed from 43 Material®. It features an inner diameter of 0.193 inches (4.90 mm), an outer diameter of 0.375 inches (9.53 mm), and a length of 0.410 inches (10.41 mm). The component provides a minimum impedance of 80 Ohms at 100 MHz. This NiZn ferrite core is designed for high-frequency common-mode choke applications and electromagnetic interference suppression.

Feature Summary

• Utilizes 43 Material® nickel-zinc ferrite composition for effective high-frequency noise attenuation
• Solid cylindrical geometry allows for direct cable insertion without mounting hardware
• Burnished edges to prevent insulation damage during installation

Applications

• High-frequency common-mode chokes
• Electromagnetic interference suppression on cables
• Inductive signal filtering applications

Procurement Notes

Verify the specific material grade matches the target frequency range, as 43 Material® is optimized for higher frequencies compared to manganese-zinc alternatives. Confirm physical dimensions align with cable outer diameters to ensure proper fit. Check if burnished edges are required to protect cable jackets during assembly. Ensure the impedance specification meets the system's noise reduction requirements at the operating frequency.

Selection Notes

Select this component when broadband suppression in the higher frequency spectrum is required. The 43 Material® offers lower permeability than MnZn types, making it suitable for frequencies above typical power line ranges. Consider the inner diameter tolerance relative to the cable size. Evaluate the need for Parylene coating if environmental protection is necessary, noting that coated versions have different part number suffixes.

Part Context

This part belongs to Fair-Rite’s Shield Bead series, which provides guaranteed minimum impedance specifications over wide frequency ranges. These components are distinct from snap-on cores or toroids, offering a simple through-hole solution for cable treatment. The product line includes various materials like 73, 43, and 61 to address different frequency and bias conditions.

Replacement Considerations

Direct substitutes include other 43 Material® beads with similar impedance profiles, such as the 2643004101 or 2643004201, though dimensional differences must be verified. Alternative materials like 31 or 61 offer different frequency characteristics and should only be considered if the application bandwidth changes.
