2643302502

Overview

Fair-Rite 2643302502 is a solid round ferrite cable core utilizing Material 43 for EMI suppression. It features an inner diameter of 4.1 mm, an outer diameter of 8.75 mm, and an external length of 18.35 mm. The component provides an impedance of 122 ohms at 100 MHz and an inductance of 2.817 nH. Designed as a shield bead, it operates effectively within the 25 MHz to 300 MHz frequency range.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Material 43 composition optimized for high-frequency noise attenuation
• Round geometry suitable for shielding beads and cable wraps

Applications

• Electromagnetic interference suppression on signal cables
• Shield bead applications for connector cabling
• High-frequency noise filtering in electronic assemblies

Procurement Notes

Verify the specific impedance value against official Fair-Rite datasheets, as distributor listings may vary between 122 ohms and 168 ohms at 100 MHz. Confirm physical dimensions match design requirements, noting discrepancies between 4.1 mm and 4.29 mm inner diameter claims across sources. Ensure Material 43 specification aligns with intended frequency performance needs.

Selection Notes

Select this component when a solid round ferrite core is required for cable-mounted EMI suppression. Material 43 offers balanced permeability for broadband noise reduction. Verify that the 4.1 mm or 4.29 mm inner diameter accommodates the target cable bundle size without excessive force during installation.
