2643540002

Ferrite Cable Overview

Fair-Rite 2643540002 is a round cable EMI suppression core constructed from Material 43. It provides a guaranteed minimum impedance of 250 ohms at 100 MHz, operating effectively within the 25-300 MHz frequency range. The component features a cylindrical design with an outer diameter of 0.562 inches (14.25 mm) and an inner diameter of 0.250 inches (6.35 mm). This snap-fit ferrite bead is engineered for direct installation onto cables to mitigate electromagnetic interference.

Ferrite Cable Feature Summary

• Snap-fit cylindrical design for rapid manual installation on cables
• Material 43 composition optimized for high-frequency noise attenuation
• Guaranteed minimum impedance specification ensures consistent EMI suppression performance

Ferrite Cable Applications

• Suppression of electromagnetic interference on round cables
• High-frequency noise filtering in electronic assemblies
• Cable protection in the 25-300 MHz operational spectrum

Ferrite Cable Procurement Notes

Verify the specific impedance tolerance and material grade against the official Fair-Rite datasheet before integration. Confirm that the inner diameter accommodates the target cable assembly dimensions. Ensure compliance with RoHS directives if required by the end application. Cross-reference the manufacturer part number to avoid confusion with similar snap-fit cores.

Ferrite Cable Selection Notes

Select this component when a snap-fit solution is preferred over split-core types for permanent cable installations. Material 43 is suitable for applications requiring effective attenuation in the VHF/UHF bands. Verify that the 0.250-inch inner diameter matches the cable bundle size to ensure a secure fit without excessive force during installation.

Ferrite Cable Part Context

This component belongs to the Fair-Rite round cable EMI suppression core series. It utilizes Material 43, a standard nickel-zinc ferrite formulation known for its resistive characteristics at higher frequencies. The product line focuses on providing reliable, pre-formed cores for straightforward cable management and noise reduction tasks.

Ferrite Cable Replacement Considerations

Substitute only with Fair-Rite parts sharing the same Material 43 designation and compatible physical dimensions. Verify that alternative snap-fit cores maintain the 250-ohm minimum impedance at 100 MHz to preserve circuit noise immunity levels.
