SB28B3012

Overview

The SB28B3012 is a hinged snap-on ferrite core from the LeaderTech FerriShield series, designed for cable bundle EMI suppression. It utilizes material grade 28 to provide an impedance of 105 Ohms at 100 MHz. The component features a flat design with a circular inner diameter of 64.50 mm and external dimensions of 76.20 mm in width by 6.40 mm in height.

Feature Summary

• Hinged snap-on design allows for easy installation around existing cables without disconnection
• Utilizes high-permeability ferrite material for effective broadband noise attenuation
• Flat profile construction facilitates mounting in space-constrained environments

Applications

• Suppression of electromagnetic interference on large-diameter cable bundles
• Noise reduction in industrial equipment wiring harnesses
• EMI mitigation in telecommunications infrastructure cabling

Procurement Notes

Verify the specific material grade and impedance specifications against the official datasheet before procurement. Confirm that the internal diameter accommodates the target cable bundle diameter with appropriate clearance. Ensure the hinged mechanism integrity is suitable for the intended mechanical environment.

Selection Notes

Select this component when a non-invasive solution for large cable diameters is required. The snap-on design eliminates the need to disconnect cables during installation. Consider the operating frequency range where the 105 Ohm impedance provides optimal attenuation characteristics for the specific noise spectrum present.

Part Context

This part belongs to the SB28 series of saddle bead and hinged ferrite cores manufactured by LeaderTech. These components are categorized under passive EMI/RFI suppression devices. The series offers various sizes and materials to address different cable diameters and frequency requirements in electronic systems.

Replacement Considerations

Direct substitutes include other hinged ferrite cores with similar internal diameters and impedance ratings. Verify compatibility with material grade 28 characteristics if replacing with alternative brands. Ensure mechanical fit within the enclosure or mounting area.
