FA28B2440

Overview

The FA28B2440 is a hinged ferrite core manufactured by Leader Tech Inc., designed for flat ribbon cables. It belongs to the 28 material series, providing effective electromagnetic interference suppression. The component features a hinged design for easy installation around existing cabling without disconnection. Key physical dimensions include an internal length of 50.8 mm and an external length of 63.5 mm. The external width measures 50.8 mm, while the external height is 12.7 mm. The internal height accommodates a cable thickness of 1.0 mm. The unit weighs approximately 68.35 grams and is supplied in bulk packaging.

Feature Summary

• Hinged construction allows for non-intrusive installation over flat ribbon cables
• Utilizes high-permeability ferrite material for broadband noise attenuation
• Adhesive backing option available for secure mounting on surfaces

Applications

• Suppression of electromagnetic interference in flat ribbon cable assemblies
• Noise reduction in data transmission lines within electronic equipment
• EMI mitigation in computer peripheral connections

Procurement Notes

Verify the specific adhesive configuration required, as some variants include bottom-mounted adhesive strips while others may not. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement. Ensure the internal cable dimensions match the target ribbon cable thickness to guarantee proper fit and magnetic coupling efficiency.

Selection Notes

Select this component when dealing with flat ribbon cables requiring snap-on EMI protection. The 28 material grade offers a balance of permeability and frequency response suitable for general digital noise suppression. Consider the hinged mechanism for maintenance-friendly designs where cable removal is frequent. Verify that the external dimensions fit within the available chassis or enclosure space constraints.

Part Context

This part falls under Leader Tech's ferrite clamp-on cores category, specifically engineered for flat cable applications. It complements other EMI suppression solutions like saddle beads and round cable clamps within the same product family. The FA28 series is widely used in industrial and commercial electronics for maintaining signal integrity by attenuating common-mode noise currents on parallel conductors.

Replacement Considerations

Cross-reference with similar hinged ferrite cores from other manufacturers if supply constraints exist. Ensure substitute parts maintain compatible internal dimensions for the specific flat cable gauge. Verify that alternative materials offer comparable impedance characteristics at the target noise frequencies.
