SS28B2040

Overview

The SS28B2040 is a square ferrite clamp-on core manufactured by Leader Tech Inc. It utilizes material grade 28 and features a hinged design for easy installation around cables. The component has an inside diameter of 14 mm, with external dimensions of 31.8 mm in length, 29.3 mm in width, and 28.6 mm in height. It provides an impedance of 230 ohms at 700 MHz.

Feature Summary

• Hinged snap-fit design allows for quick installation on existing cable assemblies without disconnection.
• Square cross-section geometry optimizes magnetic coupling for specific cable bundles.
• Material grade 28 composition targets high-frequency noise suppression performance.

Applications

• Suppression of electromagnetic interference on data communication cables
• Noise reduction on power supply lines in electronic equipment
• Cable management and shielding in industrial control systems

Procurement Notes

Verify the exact impedance value and frequency response curve against the official Leader Tech datasheet before integration. Confirm that the 14 mm internal diameter accommodates the target cable bundle including insulation. Ensure compliance with RoHS directives if required by the end application environment.

Selection Notes

Select this part when a split-core solution is necessary for retrofitting or maintenance access. The 14 mm bore size suits medium-diameter cables. Compare impedance characteristics at the specific operating frequency against other material grades to ensure adequate attenuation requirements are met for the noise spectrum present.

Part Context

This component belongs to the Leader Tech Ferrishield series of clamp-on ferrite cores. These products are designed to suppress common-mode noise on cables. The SS prefix typically denotes a sleeve-style snap fit, while the numeric suffix indicates specific dimensional and material properties within the product family.

Replacement Considerations

Direct substitutes include SS25B2040 and SS33B2040 from the same manufacturer. These alternatives share identical physical dimensions but utilize different ferrite materials (Grade 25 and Grade 33 respectively), resulting in distinct impedance profiles. Verify that the alternative material's frequency response matches the noise suppression requirements of the original design.

FAQ
