SB28B2031AT

Overview

The SB28B2031AT is a hinged snap-on ferrite core designed for free-hanging cable applications. It provides electromagnetic interference suppression with an impedance of 45 Ohms at 100 MHz. The component features a circular inner diameter of 0.350 inches (8.90 mm) and external dimensions of 0.535 inches in width by 0.272 inches in height (13.60 mm x 6.91 mm). This passive EMI filter is constructed to clamp around cables, offering a secure mechanical fit without requiring adhesives or tools for installation.

Feature Summary

• Hinged snap-on design allows for easy installation onto existing cables
• Provides effective electromagnetic interference attenuation
• Free-hanging configuration suitable for various cable routing needs

Applications

• Cable shielding in electronic enclosures
• Interconnect cable EMI suppression
• Circuit board output line filtering

Procurement Notes

Verify the specific impedance value and physical dimensions against the official Leader Tech datasheet before integration. Confirm that the cable diameter falls within the specified inner diameter tolerance to ensure proper clamping force. Check for RoHS compliance status if required by your manufacturing standards. Ensure the part number suffix matches the exact material and housing specifications needed for your application environment.

Selection Notes

Select this component when a non-permanent, tool-free ferrite solution is required for cable management. The hinged design facilitates maintenance and retrofitting on live systems. Consider the operating frequency range where the 45 Ohm impedance provides optimal noise reduction. Evaluate the physical space constraints to accommodate the outer dimensions of the core assembly.

Part Context

Leader Tech Inc. specializes in EMI shielding products for circuit boards, electronic enclosures, and interconnect cables. The SB28B2031AT belongs to their range of ferrite cores and clamshell filters designed to mitigate high-frequency noise.
