SB28B2043AB

Overview

The SB28B2043AB is a hinged cable ferrite manufactured by Leader Tech Inc., designed for electromagnetic interference suppression. It features a Type 28 material composition providing an impedance of 125 Ohms at 100MHz. The component has a hinged design allowing for free-hanging installation around cables. Internal dimensions include a 0.752-inch (19.10mm) diameter bore, while external dimensions measure 1.398 inches wide by 0.701 inches high, with a total length of 1.500 inches (38.10mm).

Feature Summary

• Hinged construction enables easy installation and removal around existing cables without disconnection.
• Utilizes Type 28 ferrite material to provide effective noise attenuation in the specified frequency range.
• Free-hanging mounting style allows flexible positioning on wires and harnesses.

Applications

• Suppression of electromagnetic interference on interconnect cables.
• Noise filtering in electronic enclosures and circuit board assemblies.
• EMI mitigation for signal and power transmission lines.

Procurement Notes

Verify that the required impedance specification matches the application's noise profile, as this unit provides 125 Ohms at 100MHz. Confirm compatibility with the target cable diameter, which must not exceed the 0.752-inch internal bore. Check for RoHS3 compliance requirements if operating in regulated environments. Ensure the hinged mechanism remains secure during operation to maintain consistent shielding performance.

Selection Notes

Select this model when a reusable, non-destructive installation method is required for cable management. The 125 Ohm impedance level suits applications targeting mid-frequency noise suppression. Consider the physical dimensions to ensure adequate clearance within the equipment chassis. Compare against other Leader Tech Series SB units if different impedance values or bore sizes are necessary for specific cable bundles.

Part Context

This component belongs to the Leader Tech EMI shielding product line, specifically categorized under cable ferrites. It is part of the broader family of solutions for circuit boards and electronic enclosures. The manufacturer specializes in innovative shielding products, and this item represents their standard hinged ferrite offering for general-purpose EMI suppression tasks.

Replacement Considerations

The SB28B2043 is documented as a parameter-equivalent substitute. Verify that the base model meets all dimensional and electrical specifications before adoption.
