FA28B2500

Overview

The FA28B2500 is a hinged snap-on ferrite core clamp designed for flat ribbon cables. It features a rectangular cross-section with an internal width of 52.00 mm and an internal height of 1.50 mm. The external dimensions are 80.77 mm in length, 52.00 mm in width, and 20.32 mm in height. The component provides an impedance of 325 Ohms at 100 MHz. It is constructed from ferrite material housed within a protective case, allowing for easy installation over existing cable assemblies without disconnection.

Feature Summary

• Hinged snap-on design enables rapid installation over flat ribbon cables without disconnecting the signal path.
• High impedance characteristic of 325 Ohms at 100 MHz effectively suppresses electromagnetic interference on high-speed data lines.
• Rectangular internal geometry is specifically engineered to accommodate flat ribbon cable profiles securely.

Applications

• Suppression of common mode noise on parallel data buses
• EMI mitigation for flat ribbon cable interconnects in computing hardware
• Signal integrity enhancement in high-speed digital communication links

Procurement Notes

Verify the specific impedance value and frequency rating against the manufacturer's current datasheet before integration. Confirm that the internal cable dimensions fit within the specified 52.00 mm by 1.50 mm aperture. Ensure the hinged mechanism remains functional during handling. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when retrofitting EMI suppression onto existing flat ribbon cables is required. The hinged form factor eliminates the need to disconnect connectors, reducing assembly time. Ensure the target cable thickness does not exceed 1.50 mm to maintain proper clamping force. Verify that the 325 Ohm impedance profile matches the noise frequencies present in the application environment.

Part Context

This part belongs to LeaderTech's line of clamp-on ferrite cores, which are passive components used for electromagnetic interference suppression. Unlike split-core designs that require opening, these hinged units offer a secure closure mechanism. They are distinct from bead-style ferrites as they encase the entire cable width rather than surrounding a single conductor.

Replacement Considerations

Direct substitutes must match the 52.00 mm width, 1.50 mm height, and 325 Ohm @ 100 MHz impedance. Verify that alternative parts also feature a hinged snap-on mechanism for compatible installation methods.
