FC28B2480

Overview

The FC28B2480 is a hinged ferrite core clamp designed for flat ribbon cables. It features an internal dimension of 52.00 mm width by 1.50 mm height and an external dimension of 80.80 mm width by 20.30 mm height, with a length of 28.60 mm. The component utilizes material grade 28, providing an impedance of 250 Ohms at 100 MHz. It is packaged in bulk quantities.

Feature Summary

• Hinged snap-on design allows for easy installation over existing flat cable assemblies without disconnection.
• Free-hanging configuration enables flexible positioning along the cable run to target specific noise sources.
• High impedance rating of 250 Ohms at 100 MHz provides effective suppression of high-frequency electromagnetic interference.

Applications

• Suppression of common-mode noise on parallel flat ribbon cables in digital systems
• EMI mitigation in computer peripheral interconnects
• Noise filtering in industrial control panel wiring harnesses

Procurement Notes

Verify that the target flat cable dimensions strictly fit within the 52.00 mm width and 1.50 mm height internal aperture. Confirm that the required impedance profile aligns with the 250 Ohm specification at 100 MHz for the specific frequency spectrum of the application. Ensure the hinged mechanism remains functional during handling and installation.

Selection Notes

Select this part when dealing with wide flat ribbon cables requiring robust mechanical retention via a hinge. Compare against non-hinged clamp-ons if permanent attachment is preferred. Consider the 250 Ohm impedance value relative to the noise frequencies present; lower impedance materials may be suitable for different spectral requirements.

Part Context

Leader Tech manufactures this component as part of its ferrite clamp-on core series. These cores are engineered for post-assembly EMI suppression. The FC28B2480 specifically targets flat cable geometries, distinguishing it from cylindrical or split-core designs intended for round wires.

Replacement Considerations

Cross-reference Leader Tech models FA28B2480 or RA28B2480 for similar hinged flat cable solutions. Verify dimensional compatibility and impedance characteristics before substituting, as material grades and physical sizes vary across the product line.
