2643163851

Overview

Fair-Rite 2643163851 is a split ferrite core designed for flat ribbon cables. It utilizes Material 43 to provide impedance characteristics suitable for high-frequency noise suppression. The component exhibits an impedance of 220 ohms at 100 MHz and operates effectively within the 25 MHz to 300 MHz frequency range. Physical dimensions include an internal length of 26.67 mm, an external width of 38.10 mm, and an external height of 12.07 mm. It supports a maximum operating temperature of +125°C and complies with RoHS standards.

Feature Summary

• Split design allows installation on existing flat ribbon cables without disconnecting conductors
• Material 43 composition provides effective magnetic permeability for broadband noise attenuation
• Flat geometry accommodates standard ribbon cable profiles for compact integration

Applications

• Electromagnetic interference suppression on parallel data buses
• Noise filtering for flat ribbon cable assemblies in computing hardware
• Signal integrity enhancement for high-speed digital interconnects

Procurement Notes

Verify that the specific part number matches the required impedance and material specifications for your application. Confirm physical compatibility with the target flat cable dimensions before procurement. Ensure compliance with relevant environmental regulations such as RoHS if applicable to your region. Check manufacturer documentation for any updates regarding material composition or testing standards.

Selection Notes

Select this component when dealing with flat ribbon cables requiring broadband noise suppression in the VHF/UHF range. Material 43 is appropriate for general-purpose EMI reduction where moderate permeability is sufficient. Consider the internal dimensions to ensure the cable fits securely within the split core. Evaluate the operating temperature range against your system's thermal environment.

Part Context

This component belongs to Fair-Rite's series of split ferrite cores intended for post-assembly installation. It is distinct from solid cores used during manufacturing. The product line focuses on providing flexible EMI solutions for various cable types, including round and flat configurations, supporting diverse electronic packaging requirements.

Replacement Considerations

Direct substitutes must match the 220 ohm impedance at 100 MHz and Material 43 composition. Verify dimensional compatibility, particularly the internal width and height, to ensure proper fit on the target flat cable. Alternative parts from other manufacturers should offer similar frequency response characteristics.
