2643540102

Ferrite Cable Overview

Fair-Rite 2643540102 is a solid free-hanging ferrite core designed for EMI suppression. It utilizes Material 43, providing an impedance of 89 Ohms at 100 MHz. The component features a circular shape with an inner diameter of 0.250 inches (6.35 mm) and an outer diameter of 0.562 inches (14.28 mm). Its length measures 0.400 inches (10.16 mm). This snap-on style core is intended for cable wrapping to mitigate high-frequency noise.

Ferrite Cable Feature Summary

• Solid construction with snap-on design for easy installation around cables
• Material 43 composition optimized for common-mode noise suppression in the VHF range
• Free-hanging configuration allows flexible placement on wires

Ferrite Cable Applications

• Power supply output filtering
• Battery charger cable noise reduction
• Portable device cable EMI mitigation

Ferrite Cable Procurement Notes

Verify the specific Material 43 designation and impedance tolerance against the official Fair-Rite datasheet before integration. Confirm that the 89 Ohm rating at 100 MHz aligns with your target frequency spectrum. Ensure the 6.35 mm inner diameter accommodates the maximum cable bundle thickness without excessive strain on the core housing.

Ferrite Cable Selection Notes

Select this part when a solid, non-split ferrite core is required for permanent or semi-permanent cable installations. Material 43 is suitable for frequencies between 10 MHz and 100 MHz. Compare the 89 Ohm impedance against higher-impedance alternatives if stronger attenuation is needed at lower frequencies within the VHF band.

Ferrite Cable Part Context

This component belongs to the Fair-Rite Cable Ferrites category, specifically utilizing Material 43 for general-purpose EMI suppression. It serves as a passive filter element to absorb high-frequency interference on signal and power lines.

Ferrite Cable Replacement Considerations

Direct substitutes include other Material 43 cores with similar dimensions, such as Fair-Rite 2643540101 variants, provided the impedance profile matches the application requirements.
