2643375002

Overview

Fair-Rite 2643375002 is a solid round ferrite cable core designed for EMI suppression. It utilizes Material 43, providing an impedance of 115 ohms at 100 MHz. The component features a 4.88 mm inner diameter and a 9.53 mm outer diameter, with a length of 14.5 mm. Classified as a shield bead, it operates effectively within the frequency range of 25 MHz to 300 MHz. The unit is RoHS compliant and packaged in bulk quantities.

Feature Summary

• Solid construction provides structural integrity for snap-on installation
• Material 43 composition ensures high magnetic permeability for noise attenuation
• Round geometry accommodates various cable diameters

Applications

• EMI suppression components
• Cable noise filtering
• Signal line protection

Procurement Notes

Verify the specific impedance tolerance and material batch consistency against the official Fair-Rite datasheet before integration. Confirm that the 115-ohm specification at 100 MHz aligns with your circuit's noise profile requirements. Ensure compliance with RoHS directives if operating in regulated environments. Cross-reference the physical dimensions to guarantee fitment on target cables.

Selection Notes

Select this part when a solid, non-split ferrite bead is required for permanent or semi-permanent cable treatment. Material 43 is optimal for general-purpose noise suppression in the VHF/UHF range. Compare the 4.88 mm bore size against existing cable bundles to ensure proper clearance without excessive movement.

Part Context
