2643000301

Overview

Fair-Rite Products Corp. part number 2643000301 is a solid cylindrical ferrite core designed for EMI suppression applications. The component utilizes Fair-Rite Material 43, providing an impedance of 83 ohms at a test frequency of 100 MHz. It features a round shape with free-hanging installation and operates within a frequency range of 25 MHz to 300 MHz. Physical dimensions include an outer diameter of 3.5 mm, an inner diameter of 1.3 mm, and a length of 6 mm. The product is RoHS compliant and currently active.

Feature Summary

• Solid cylindrical construction made from Material 43 for effective high-frequency noise attenuation
• Free-hanging design allows for direct sliding onto cables without additional mounting hardware
• Guaranteed minimum impedance specification ensures consistent EMI suppression performance

Applications

• Suppression of electromagnetic interference on data and power cables
• Noise reduction in high-frequency signal transmission lines
• Component integration in electronic assemblies requiring cable shielding

Procurement Notes

Verify the specific impedance value and material composition against the official Fair-Rite datasheet prior to procurement. Confirm that the physical dimensions match the required cable diameter for proper fit. Ensure compliance with relevant environmental regulations such as RoHS requirements for the intended market. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when a solid, non-split ferrite bead is required for permanent cable installation. Material 43 is suitable for frequencies between 25 MHz and 300 MHz, making it appropriate for digital signal noise suppression. Ensure the cable diameter fits within the 1.3 mm inner diameter constraint. Consider the 83 ohm impedance at 100 MHz as the primary metric for filtering effectiveness in the target application spectrum.

Part Context

This component belongs to the Fair-Rite 26 series of shield beads. These are solid ferrite cores distinct from split or clamp-on types, requiring the cable end to be threaded through during assembly. They are commonly used in conjunction with other EMI suppression strategies to meet regulatory emissions standards for electronic equipment operating in the VHF/UHF bands.

Replacement Considerations
