FD33B2480

Overview

The FD33B2480 is a hinged ferrite core manufactured by Leader Tech Inc., designed for flat cable applications. It utilizes Material 33, providing an impedance of 31 Ohms at 30MHz. The component features a hinged design for easy installation around cables without disconnection. Internal dimensions are 52.00mm x 1.50mm, while external dimensions measure 70.10mm x 17.80mm with a length of 33.30mm. It is supplied in bulk packaging and is currently in production.

Feature Summary

• Hinged construction allows secure closure around flat ribbon cables
• Material 33 composition provides specific high-frequency noise suppression characteristics
• Designed specifically for flat cable geometries to ensure effective EMI filtering

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Noise reduction in data transmission lines using flat connectors
• EMI filtering in electronic assemblies requiring non-invasive cable treatment

Procurement Notes

Verify the exact material grade and impedance specifications against the official Leader Tech datasheet before integration. Confirm that the internal cavity dimensions accommodate the target flat cable thickness and width. Ensure the hinged mechanism functions correctly for the intended assembly process. Check for RoHS compliance status if required by the final product regulations.

Selection Notes

Select this component when working with flat ribbon cables rather than round wires. The Material 33 formulation is suitable for frequencies around 30MHz where 31 Ohms impedance is required. Compare internal dimensions against the cable bundle size to ensure a proper fit. Consider the hinged style for ease of maintenance compared to snap-on or adhesive types.

Part Context

This part belongs to the Leader Tech ferrite clamp-on core family, specifically engineered for flat cable applications. It shares design similarities with other hinged models like RA33B2480 but is distinct in its specific dimensional profile and intended use case for flat conductors. The series focuses on providing accessible EMI solutions for bus structures and parallel data lines.

Replacement Considerations

RC33B2480 is listed as a parameter-equivalent alternative. Verify that the RC33B2480 matches the required hinged configuration and dimensional constraints. Ensure the impedance characteristics remain consistent for the specific frequency range of the application.
