2643002402

Overview

The Fair-Rite Products Corp. part number 2643002402 is a solid free-hanging ferrite core designed for EMI suppression applications. Constructed from Material 43, this component provides a guaranteed minimum impedance of 43 Ohms at 100 MHz. The bead features an internal diameter of 0.197 inches (5.00 mm), an external diameter of 0.380 inches (9.65 mm), and a length of 0.190 inches (4.83 mm). It is classified as a circular type with a solid design intended for direct cable installation.

Feature Summary

• Solid construction eliminates the need for assembly hardware
• Material 43 composition optimized for broadband noise attenuation
• Guaranteed impedance specifications ensure consistent performance

Applications

• Suppression of electromagnetic interference on single conductors
• Noise filtering for high-speed digital signal lines
• EMI mitigation in compact electronic assemblies

Procurement Notes

Verify that the required impedance specification aligns with Material 43 characteristics for the target frequency range. Confirm that the internal diameter accommodates the specific cable or wire gauge in use. Ensure compliance with RoHS3 standards if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a solid, non-split ferrite bead is required for permanent installation. Material 43 is suitable for frequencies ranging from approximately 1 MHz to several hundred MHz. Consider the physical dimensions to ensure adequate clearance within the enclosure layout.

Part Context

This item belongs to the Fair-Rite Shield Bead series, which offers various sizes and materials for EMI control. Part numbers ending in '2' indicate that the beads are supplied burnished to break sharp edges, enhancing safety during handling and installation compared to unburnished variants.

Replacement Considerations

Direct substitutes include other solid ferrite beads using Material 43 with compatible internal diameters. Verify that alternative components meet the same 43 Ohm minimum impedance requirement at 100 MHz to maintain equivalent noise suppression performance.
