2643165451

Overview

Fair-Rite 2643165451 is a free-hanging solid ferrite cable core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing an impedance of 275 ohms at 100 MHz. The component features a circular geometry with an inner diameter of 6.60 mm (0.260 inches), an outer diameter of 15.00 mm (0.591 inches), and a length of 15.25 mm (0.600 inches). It is supplied in bulk packaging.

Feature Summary

• Solid cylindrical design for secure cable retention
• Material 43 composition optimized for high-frequency noise attenuation
• Free-hanging installation method requiring no mounting hardware

Applications

• Suppression of electromagnetic interference in computer peripherals
• Noise filtering on USB cables
• Attenuation of common-mode noise on power cords
• Interference reduction on communication lines

Procurement Notes

Verify the specific impedance value and material grade against the manufacturer's current datasheet prior to ordering. Confirm that the physical dimensions match the target cable diameter to ensure proper fit. Check RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable assembly. Material 43 is suitable for applications involving higher frequency noise spectra. Ensure the cable diameter falls within the 6.60 mm inner diameter tolerance for effective magnetic coupling.

Part Context

This part belongs to the Fair-Rite ferrite cable core product line, which offers various materials and geometries for EMI suppression. The 2643 series typically denotes standard free-hanging cores. Material 43 is distinct from other grades like 31 or 61, offering specific permeability characteristics for broadband noise reduction.

Replacement Considerations

Direct substitutes must match the 275 ohm @ 100 MHz impedance and Material 43 composition. Alternative Fair-Rite part numbers with identical dimensions and material properties may be used. Verify that any replacement maintains the same free-hanging form factor.
