2643540302

Ferrite Cable Overview

Fair-Rite Products Corp. part number 2643540302 is a solid, free-hanging ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43 and exhibits an impedance of 118 ohms at 100 MHz. The component features a cylindrical geometry with an inner diameter of 7.11 mm (0.280 inches), an outer diameter of 14.28 mm (0.562 inches), and a length of 15.24 mm (0.600 inches). This configuration allows for direct installation over cables without additional mounting hardware.

Ferrite Cable Feature Summary

• Solid construction provides structural integrity for free-hanging cable applications
• Material 43 composition offers high permeability for effective noise absorption in the specified frequency range
• Cylindrical shape facilitates easy sliding onto wires and cables

Ferrite Cable Applications

• Electromagnetic interference suppression on single conductors
• Common mode noise reduction on data and power lines
• Shield bead implementation for cable assemblies

Ferrite Cable Procurement Notes

Verify that the required cable diameter does not exceed the 7.11 mm inner diameter specification to ensure proper fit. Confirm that the operating environment temperature remains within the material's rated limits. Check for RoHS compliance documentation if regulatory adherence is mandatory for the final assembly. Ensure the solid design meets mechanical constraints where split cores are not permitted.

Ferrite Cable Selection Notes

Select this component when a fixed, non-opening ferrite bead is required for permanent cable treatment. Material 43 is suitable for frequencies between 10 MHz and several hundred MHz. Compare impedance characteristics against other materials if the primary noise frequency falls outside the optimal range for Material 43. Ensure the physical dimensions accommodate the available space in the device chassis or cable routing path.

Ferrite Cable Part Context

This part belongs to the Fair-Rite round cable core series, specifically designated as a shield bead. It is distinct from openable or snap-on variants due to its solid, one-piece construction. The numbering system indicates the material type, shape, and specific dimensional code assigned by the manufacturer for inventory and engineering reference.

Ferrite Cable Replacement Considerations

Direct substitutes must match the 118 ohm impedance at 100 MHz and the 7.11 mm inner diameter. Alternative Fair-Rite parts using Material 43 with identical external dimensions may be considered if availability differs. Verify that any replacement maintains the same solid construction method.
