SB28B1729

Overview

The SB28B1729 is a saddle bead ferrite core manufactured by LeaderTech Inc., designed for electromagnetic interference suppression on flat ribbon cables. It features a solid construction without adhesive backing, distinguishing it from the SA28B1729 variant which includes an adhesive layer. The component measures 28.6 mm in length and 6.9 mm in width, with a thickness of 14.2 mm. It belongs to the SB28 series and is packaged in bulk quantities.

Feature Summary

• Saddle bead design specifically engineered for flat ribbon cable applications
• Solid ferrite construction without integrated adhesive backing
• Compatible with standard EMI shielding enclosures to manage cable-borne emissions

Applications

• Suppression of electromagnetic interference on flat ribbon cables within shielded electronic enclosures
• Integration into embedded electronics systems requiring cable-based noise reduction
• EMI mitigation in equipment where non-adhesive mounting solutions are required

Procurement Notes

Verify the absence of adhesive when ordering this specific part number, as the SA28B1729 variant includes an adhesive bottom. Confirm that the internal dimensions of the target flat ribbon cable fit within the core's aperture. Ensure compliance with RoHS3 specifications if required by the end application. Check for parameter-equivalent substitutes like the SB28B0550AB if availability is constrained.

Selection Notes

Select this component when a non-adhesive ferrite solution is necessary for flat ribbon cables. Differentiate between the SB28B1729 (no adhesive) and SA28B1729 (with adhesive) based on mechanical mounting requirements. Ensure the physical dimensions align with the available space in the assembly. Consider the material properties of the ferrite core for the intended frequency range of interference suppression.

Part Context

This component is part of the FerriShield line from LeaderTech, focusing on managing electromagnetic energy leakage through cabling in shielded environments. It serves as a passive filtering element to enhance the overall shielding effectiveness of electronic assemblies by suppressing common-mode noise on data and power lines.

Replacement Considerations

Public documentation identifies no direct substitute part numbers for the SB28B1729. Verify compatibility with existing mechanical fixtures before attempting substitution.
