2643540402

Ferrite Cable Overview

Fair-Rite 2643540402 is a solid round ferrite cable core designed for EMI suppression. It utilizes Material 43, providing an impedance of 215 ohms at 100 MHz. The component features a circular geometry with a 7.26 mm inner diameter and an outer diameter of 12.7 mm. Its length measures 19.05 mm. This free-hanging core is suitable for sliding onto cables to attenuate high-frequency noise.

Ferrite Cable Feature Summary

• Solid construction provides structural integrity for direct cable application
• Material 43 composition optimized for high-frequency noise attenuation
• Free-hanging design allows easy installation over existing wiring

Ferrite Cable Applications

• Electromagnetic interference suppression on signal cables
• Noise reduction in data transmission lines
• High-frequency common-mode choke applications

Ferrite Cable Procurement Notes

Verify the specific impedance value of 215 ohms at 100 MHz against your frequency requirements. Confirm that the 7.26 mm inner diameter accommodates the target cable bundle size. Ensure Material 43 characteristics align with the intended noise spectrum. Check RoHS compliance status if required by project specifications.

Ferrite Cable Selection Notes

Select this part when a solid, non-split core is preferred for permanent or semi-permanent installations. Material 43 is ideal for frequencies above 10 MHz. Compare dimensions against available space constraints. Consider split-core alternatives if retrofitting existing terminated cables without disconnection is necessary.

Ferrite Cable Part Context

This component belongs to Fair-Rite's 2643 series of round cable ferrites. These cores are widely used in electronic assemblies requiring passive EMI filtering. The 2643 series offers various materials and sizes to match specific impedance profiles and cable diameters across different industrial and commercial applications.

Ferrite Cable Replacement Considerations

Check Fair-Rite datasheets for other Material 43 cores with similar impedance curves. Verify dimensional compatibility before substituting. Ensure the replacement maintains the required 215 ohm performance at the operating frequency.
