FA28B0071

Overview

The FA28B0071 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc., designed specifically for flat ribbon cables. It features a rectangular cross-section with internal dimensions of 13 mm in length and 1.5 mm in height, accommodating flat cable geometries. The component provides an impedance of 49 ohms at 100 MHz, serving as an effective electromagnetic interference (EMI) suppression device. It includes an adhesive backing for secure attachment to surfaces or cable assemblies. The core material is specified as type 28 ferrite, optimized for high-frequency noise attenuation in compact electronic environments.

Feature Summary

• Hinged design allows for easy installation onto existing flat ribbon cables without disconnecting the signal path.
• Integrated adhesive backing ensures permanent mounting stability on chassis or enclosure surfaces.
• Rectangular internal geometry matches standard flat cable profiles for consistent magnetic coupling.
• Type 28 ferrite composition provides targeted high-frequency noise absorption characteristics.

Applications

• Suppression of common-mode noise on parallel data bus ribbon cables
• EMI mitigation in compact consumer electronics with limited board space
• Noise filtering on internal interconnects between circuit boards
• Signal integrity enhancement in high-speed digital communication lines

Procurement Notes

Verify that the selected variant explicitly includes the adhesive feature, as non-adhesive counterparts like FC28B0071 exist within the same series. Confirm the internal cavity dimensions match the specific thickness and width of the target flat cable to ensure proper fit. Check RoHS compliance status if required by project specifications. Ensure the 49-ohm impedance rating aligns with the frequency range of the noise being suppressed.

Selection Notes

Choose this part when flat cable geometry requires a low-profile EMI solution. The hinged mechanism simplifies assembly compared to split-core alternatives that require screws. The 49-ohm impedance is suitable for general-purpose digital noise suppression. Consider the adhesive requirement; if repositionability is needed, select the non-adhesive version. Ensure the Type 28 material properties meet the specific frequency spectrum requirements of the application.

Part Context

This component belongs to Leader Tech's FerriShield line of ferrite cores, which are engineered for EMI/RFI suppression. The FA28B0071 is part of a family of flat cable clamps differentiated by adhesive presence and exact dimensional tolerances. These cores utilize manganese-zinc ferrite materials to provide high permeability and loss characteristics at radio frequencies.

Replacement Considerations

The FC28B0071 is a direct physical substitute but lacks the adhesive backing. Verify if the application permits manual securing methods if switching to the non-adhesive variant. No other direct pin-compatible substitutes are documented for this specific hinged flat cable form factor.
