SB28B2035AB

Overview

The SB28B2035AB is a hinged snap-on ferrite core manufactured by Leader Tech Inc. It provides electromagnetic interference suppression with an impedance of 65 Ohms at 100 MHz. The component features a free-hanging design suitable for cable bundles up to 0.728 inches (18.50 mm) in diameter. Physical dimensions include an outer diameter of 0.965 inches wide by 0.492 inches high (24.50 mm x 12.50 mm). It is packaged in bulk quantities.

Feature Summary

• Hinged snap-on mechanism allows for easy installation and removal around cables without disconnecting them.
• Free-hanging design accommodates cable bundles, providing RFI suppression for multiple conductors simultaneously.
• Independent circuit reaction prevents saturation when suppressing noise across different signal lines.

Applications

• Suppression of electromagnetic interference on multi-cable bundles within electronic enclosures.
• Noise reduction for data and power cables in telecommunications equipment.
• EMI mitigation in computer hardware and peripheral interconnects.
• Shielding applications for automotive wiring harnesses requiring non-invasive installation.

Procurement Notes

Verify the specific impedance rating of 65 Ohms at 100 MHz against your system's noise frequency profile to ensure effective attenuation. Confirm that the inner diameter of 0.728 inches matches the maximum bundle size you intend to shield. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the bulk packaging format aligns with your assembly line handling capabilities.

Selection Notes

Select this model when a non-invasive, reusable shielding solution is required for existing cable assemblies. The hinged design is preferable over split-core or clamp-on types where frequent access or reconfiguration is necessary. Consider the physical footprint constraints, as the outer dimensions are approximately 24.50 mm by 12.50 mm. This part is suitable for applications where cable movement does not require rigid mounting, leveraging its free-hanging capability.

Part Context

This component belongs to the SB28 series of EMI/RFI suppressors from Leader Tech Inc., a manufacturer specializing in shielding technologies for circuit boards and interconnects. The series includes various ferrite cores designed for different cable diameters and impedance requirements. These products are engineered to meet stringent electromagnetic compatibility standards for modern electronic devices.

Replacement Considerations

Direct substitutes may include other hinged ferrite cores with similar 65 Ohm impedance and compatible inner diameters. Verify mechanical fitment carefully, as variations in hinge strength or outer dimensions can affect installation stability. Alternative brands should be evaluated for material consistency and long-term durability under identical operating conditions.
