AS28B2044

Overview

The AS28B2044 is a ferrite clamp-on core manufactured by Leader Tech Inc., designed for electromagnetic interference suppression. It features a square box sleeve shape with a snap-fit closure and an adhesive base for secure mounting. The component has an inside diameter of 20.1 mm, an outside length of 45.7 mm, an outside width of 43.2 mm, and an outside height of 45.7 mm. It is supplied in bulk packaging.

Feature Summary

• Snap-on hinged design allows for easy installation around cables without disconnection
• Integrated adhesive base provides permanent mounting stability on surfaces
• Square box sleeve construction offers comprehensive shielding coverage

Applications

• EMI suppression for single round cables
• Shielding of electronic wiring harnesses
• Cable noise reduction in electronic enclosures

Procurement Notes

Verify the specific adhesive type and surface preparation requirements before installation to ensure proper bonding strength. Confirm that the cable diameter falls within the specified 20.1 mm internal diameter tolerance. Check RoHS compliance documentation if required for your specific regulatory environment. Ensure the snap mechanism engages fully to maintain consistent magnetic circuit integrity during operation.

Selection Notes

Select this model when a permanent, non-removable ferrite solution is required for cables up to 20.1 mm in diameter. The adhesive base distinguishes it from free-hanging variants, making it suitable for fixed installations where vibration resistance is critical. Consider the physical dimensions to ensure adequate clearance within the target enclosure or assembly space.

Part Context

This component belongs to the Ferrite Clamp On Cores category within Leader Tech's EMI shielding portfolio. It is part of the FerriShield line, which specializes in frequency-specific formulations for cable shielding. The product is categorized under passive components and EMI/RFI suppression materials, serving as a direct solution for high-frequency noise attenuation on conductors.

Replacement Considerations

SS28B2044 is a similar hinged ferrite core but lacks the adhesive base, functioning as a free-hanging unit. Verify if the mounting method difference impacts the mechanical stability requirements of the application.
