FA28B1785

Overview

The Leader Tech FA28B1785 is a solid flat ferrite cable core designed for electromagnetic interference suppression. It features a hinged construction with an impedance of 260 Ohms at the test frequency of 100 MHz. The component measures 34.4 mm in internal length and 1.5 mm in internal height, accommodating flat ribbon cables. Manufactured by LeaderTech, this part belongs to the Ferrite Cable Cores subcategory and is RoHS compliant.

Feature Summary

• Hinged design allows for easy installation onto existing cable bundles without disconnecting wires.
• Solid flat geometry provides effective shielding for flat ribbon cables.
• High impedance characteristic offers significant attenuation of high-frequency noise.

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Noise filtering in computer peripheral connections
• EMI mitigation in data transmission lines

Procurement Notes

Verify the specific impedance value and physical dimensions against your schematic requirements before ordering. Confirm RoHS compliance status if environmental regulations apply to your assembly. Ensure the internal cavity size matches the thickness of the target flat ribbon cable for proper fitment.

Selection Notes

Select this component when dealing with flat ribbon cables requiring high-impedance noise suppression. The hinged style facilitates retrofitting into existing assemblies. Compare the 260 Ohm impedance rating against other models like SM28B1775 or 28B0785 to determine the optimal attenuation level for your specific frequency range.

Part Context

This part falls under the LeaderTech EMI Filter / EMI Suppression category, specifically within Ferrite Cable Cores. It is distinct from snap-on cores and shield gaskets, serving as a dedicated solution for flat cable noise reduction. The product line includes various impedance ratings and form factors for diverse electronic applications.
