SB28B0221AB

Overview

The SB28B0221AB is a hinged snap-on ferrite core designed for electromagnetic interference suppression on cables and wires. It features an internal diameter of 51.10 mm (2.012 inches) and external dimensions of 12.70 mm width by 12.70 mm height. The component provides an impedance of 30 Ohms at 100 MHz and utilizes material grade 28. It is packaged in bulk quantities.

Feature Summary

• Hinged snap-on design allows for easy installation onto existing cables without disconnection.
• Free-hanging configuration enables flexible mounting orientation in various applications.

Applications

• Suppression of electromagnetic interference on high-current cables
• EMI reduction on wire harnesses in industrial equipment
• Noise filtering on power supply lines

Procurement Notes

Verify the specific internal diameter requirement, as this model accommodates large cables up to 51.10 mm. Confirm that the hinged snap-on style meets the mechanical constraints of the target assembly. Ensure compatibility with the required impedance profile of 30 Ohms at 100 MHz for the intended noise spectrum. Check RoHS compliance status if environmental regulations apply to the final product.

Selection Notes

Select this part when a non-invasive solution for cable shielding is required. The large internal diameter distinguishes it from standard small-core ferrites. Consider the physical space available for the free-hanging form factor. Material grade 28 offers specific frequency characteristics suitable for common EMI ranges. Verify that the adhesive or mounting method aligns with the system's thermal and mechanical requirements.

Part Context

This component belongs to the LeaderTech SB28 series of saddle bead ferrites. These are specialized EMI/RFI suppression components distinct from standard clamp-on cores due to their hinged construction. The series is engineered for robust noise cancellation in demanding electronic environments, providing a reliable shield against radiated and conducted emissions.

Replacement Considerations

SB28B0642 is listed as a parameter-equivalent alternative. Verify dimensional compatibility and impedance curves before substitution. Ensure the replacement maintains the same hinged snap-on functionality and material grade for equivalent performance.
