SS28B2043

Overview

The SS28B2043 is a box-shaped ferrite clamp-on suppressor manufactured by Leader Tech Inc. under the FerriShield brand. It features a snap-on design with an inside diameter of 20.1 mm and an outside length of 45.7 mm. The component provides an impedance of 260 Ohms at a test frequency of 100 MHz. It is constructed from gray material and utilizes an adhesive base for mounting. The device is designed for cable bundles up to 0.790 inches in diameter, allowing single-location RFI suppression for multiple cables while preventing saturation.

Feature Summary

• Box-shaped ferrite assembly designed for cable bundle diameters up to 0.790 inches
• Snap-on mechanism allows for easy installation on existing cable bundles
• Adhesive base option available for secure single-location mounting
• Separate circuit reaction prevents saturation when suppressing multiple cables

Applications

• EMI/RFI suppression for cable bundles up to 0.790 inches in diameter
• Single-location noise reduction for multiple parallel cables
• Board, enclosure, and interconnect cable shielding solutions

Procurement Notes

Verify the specific impedance value of 260 Ohms at 100 MHz against your system requirements. Confirm the inside diameter of 20.1 mm matches the target cable bundle size. Ensure the gray color variant is selected if aesthetic consistency is required. Check for the availability of the optional adhesive mount base if permanent installation is needed. Validate RoHS compliance status through the official datasheet before procurement.

Selection Notes

Select this component when a box-style ferrite core is required for larger cable bundles exceeding standard round core capacities. The 260 Ohm impedance at 100 MHz suits specific high-frequency noise profiles. Consider the snap-on design for maintenance-friendly installations where disassembly may be necessary. Compare with part number AS28B2044 if a variable diameter end port with flexible spring flutes is preferred over the fixed snap design.

Part Context

Leader Tech Inc. manufactures the FerriShield line of EMI shielding products, including ferrite cores for circuit boards, enclosures, and interconnect cables. The SS28B2043 belongs to the SB28 series of clamp-on ferrites. These components are engineered to provide reliable board, enclosure, and cable solutions for noise suppression in electronic systems.

Replacement Considerations

The AS28B2044 is a documented alternative featuring a variable diameter end port with flexible spring flutes. Verify that the flexible design meets the mechanical constraints of the application if replacing the fixed snap-on SS28B2043.
