2643180251

Overview

Fair-Rite 2643180251 is a solid, free-hanging ferrite core designed for flat ribbon cables. It utilizes Material 43 to provide an impedance of 130 ohms at 100 MHz across the 25 MHz to 300 MHz frequency range. The component features a flat geometry with internal dimensions of 18.01 mm and external dimensions of 29.97 mm in width and 23.11 mm in height. It operates within a temperature range of -55°C to +125°C and complies with RoHS 3 standards.

Feature Summary

• Solid construction provides structural integrity for flat cable applications
• Material 43 composition ensures effective noise suppression in high-frequency ranges
• Free-hanging design allows for easy installation on existing cable assemblies

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Noise filtering in data transmission lines operating between 25 MHz and 300 MHz
• EMI reduction in computer peripheral connections

Procurement Notes

Verify that the specific order matches the Material 43 specification and the 130-ohm impedance rating at 100 MHz. Confirm the physical dimensions align with the target flat cable thickness. Ensure compliance requirements such as RoHS 3 are documented for the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar split-core variants.

Selection Notes

Select this component when a solid, non-split core is required for permanent or semi-permanent mounting on flat cables. Material 43 is suitable for general-purpose EMI suppression in the VHF range. Consider the fixed internal dimension to ensure the cable fits securely without excessive movement. This part is distinct from hinged or split-core alternatives that allow post-assembly installation.

Part Context

This component belongs to the Fair-Rite 26 series of ferrite cable cores. It is specifically engineered for flat ribbon cables rather than round wires. The 26 series typically offers various material grades and geometries to address different impedance and mechanical constraints in electronic interconnects.

Replacement Considerations

Direct substitutes include other Fair-Rite solid flat cores with compatible internal dimensions and Material 43 properties. Verify impedance curves match the application's noise spectrum. Generic equivalents may lack the precise chemical composition required for the specified 130-ohm performance.
