SB28B3012AT

Overview

The SB28B3012AT is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It belongs to the SB28 series, utilizing material grade 28 for EMI suppression. The component features an internal diameter of 64.5 mm and an impedance of 105 Ohms at 100 MHz. Physical dimensions include an outer width of 76.2 mm and an outer height of 6.4 mm. It is designed for flat ribbon cables with specific cross-sectional constraints.

Feature Summary

• Hinged snap-on design allows installation without disconnecting cables
• Utilizes high-permeability ferrite material for effective noise attenuation
• Enclosed structure provides complete shielding around the cable

Applications

• Suppression of electromagnetic interference on flat ribbon cables
• Protection of data transmission lines in electronic assemblies
• Mitigation of common-mode noise in computer peripheral connections

Procurement Notes

Verify the exact suffix designation against the manufacturer's current catalog, as variations such as AT may indicate specific adhesive or mounting configurations not universally present in all listings. Confirm that the internal diameter matches the target cable bundle thickness to ensure proper closure of the hinge mechanism. Check RoHS compliance status directly from the official datasheet before integration into regulated products.

Selection Notes

Select this component when a non-intrusive installation method is required for existing cable harnesses. The 64.5 mm internal diameter accommodates thick flat cables or bundled wires. Ensure the operating frequency range aligns with the 105 Ohm impedance specification at 100 MHz for optimal performance. Compare physical envelope constraints against available space in the equipment chassis.

Part Context

This part falls under the Leader Tech SB28 family of ferrite clamps. These components are engineered for broadband EMI/RFI suppression. The SB28 series typically offers various sizes to fit different cable geometries while maintaining consistent magnetic properties across the product line for standardized noise reduction strategies.

Replacement Considerations

Cross-reference with other Leader Tech SB28 series parts if dimensional adjustments are needed. Verify that substitute hinged cores maintain equivalent impedance characteristics and internal clearance. No direct public substitute part numbers are confirmed in the provided documentation.
