FX28R1261-2A

Overview

The FX28R1261-2A is a hinged ferrite cable core manufactured by Leader Tech Inc. It features a magnetic material designated as type 28, providing an impedance of 135 Ohms at the standard test frequency of 100 MHz. The component has a compact physical profile with dimensions of 25.1 mm in length and 0.9 mm in width. Designed for solid flat ribbon cables, it offers a mechanical solution for EMI suppression without requiring adhesive mounting.

Feature Summary

• Hinged mechanical design allows for easy installation and removal around existing cable bundles
• Utilizes Type 28 ferrite material optimized for high-frequency noise attenuation
• Solid construction suitable for flat ribbon cable geometries

Applications

• EMI suppression on flat ribbon data cables
• Signal integrity enhancement in high-speed digital interfaces
• Noise reduction in internal computer bus connections

Procurement Notes

Verify the exact part number suffix to ensure the hinged variant is selected, as Leader Tech utilizes specific alphanumeric codes to distinguish between solid, hinged, and split-core designs. Confirm RoHS compliance status through the official datasheet or manufacturer declaration prior to procurement, as regulatory requirements may vary by production batch.

Selection Notes

Select this component when a non-destructive, reusable clamping mechanism is required for flat ribbon cables. The 135 Ohm impedance value should be matched against the target noise frequency spectrum. Ensure the cable thickness does not exceed the 0.9 mm dimension to guarantee proper closure of the hinge mechanism.

Part Context

This component belongs to the Leader Tech FX series of ferrite cores, which are engineered for electromagnetic interference mitigation in electronic interconnects. The company specializes in shielding technologies for circuit boards and enclosures, positioning this core within their broader portfolio of signal integrity solutions.

Replacement Considerations

Direct substitutes must match the 135 Ohm impedance, Type 28 material composition, and 25.1 x 0.9 mm form factor. Verify that any alternative maintains the hinged configuration for compatible installation methods.
