FD28B2375

Overview

The FD28B2375 is a hinged ferrite clamp-on core manufactured by Leader Tech Inc., designed for flat ribbon cables. It features a snap-on installation type and operates with an impedance of 195 Ohms at 100 MHz. The component has an internal length of 43.7 mm, an internal height of 1.5 mm, an external width of 80.8 mm, an external height of 20.3 mm, and an external length of 43.7 mm. It is packaged in bulk quantities.

Feature Summary

• Hinged snap-on design allows for easy installation onto existing cable assemblies without disconnecting the signal path.
• Specifically engineered for flat ribbon cables to provide targeted electromagnetic interference suppression.
• Constructed as a free-hanging unit suitable for direct attachment to cable bundles.

Applications

• Suppression of common mode noise on flat ribbon data cables
• EMI reduction in computer peripheral connections
• Signal integrity enhancement in high-speed digital interfaces

Procurement Notes

Verify the specific impedance value and frequency rating against your system requirements before procurement. Confirm that the internal dimensions match the thickness and width of the target flat ribbon cable to ensure a secure fit. Check RoHS compliance status if required by your manufacturing standards. Ensure the hinged mechanism is intact upon receipt to guarantee proper closure around the cable.

Selection Notes

Select this component when dealing with flat ribbon cables rather than round wire bundles. The 195 Ohm impedance at 100 MHz makes it suitable for general-purpose EMI suppression in digital circuits. Consider the physical size constraints, as the external dimensions are significantly larger than the cable cross-section. Verify compatibility with the cable's mechanical flexibility, as the hinged case adds some rigidity to the assembly point.

Part Context

This part belongs to the Ferrite Clamp On Cores category from Leader Tech Inc. It is distinct from sleeve-type cores due to its hinged construction. Similar models like FF28B2375 share dimensional similarities but may differ in specific impedance characteristics or casing details. It serves as a passive filter component in electronic assemblies requiring post-assembly noise mitigation.

Replacement Considerations

Cross-reference with other Leader Tech hinged ferrites such as FF28B2375 for dimensional compatibility. Verify that substitute parts maintain the same 195 Ohm @ 100 MHz impedance profile. Ensure the replacement also supports flat ribbon cable geometry. Confirm that the hinged latch mechanism functions equivalently to prevent accidental opening during operation.
