SB28B2030

Overview

The SB28B2030 is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It features an internal diameter of 8.90 mm and provides an impedance of 40 Ohms at 100 MHz. The component utilizes material grade 28 to suppress electromagnetic interference on cables and wires.

Feature Summary

• Hinged snap-on design for easy installation around existing cable bundles
• Utilizes high-permeability ferrite material for effective noise suppression
• Provides significant impedance to attenuate common-mode radio frequency interference

Applications

• Suppression of electromagnetic interference on data cables
• Noise reduction on power supply wiring harnesses
• EMI mitigation in telecommunications equipment cabling

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before procurement. Confirm that the hinged mechanism is compatible with the target cable bundle diameter. Ensure compliance with relevant environmental regulations required for the final assembly.

Selection Notes

Select this component when a non-invasive solution for cable noise suppression is required. The hinged design allows retrofitting without disconnecting cables. Choose based on the required impedance at the target noise frequency and the maximum cable diameter that fits within the core aperture.

Part Context

This part belongs to the SB28 series of ferrite cores from Leader Tech Inc., designed for EMI/RFI suppression. These components are widely used in electronic assemblies to meet regulatory emissions standards by dampening high-frequency noise on interconnecting cables.

Replacement Considerations

Check for direct substitutes with identical 40 Ohm impedance and 8.90 mm inner diameter. Verify that alternative hinged cores maintain similar mechanical retention strength and material permeability characteristics.
