SB28B2031

Overview

The SB28B2031 is a hinged snap-on ferrite core manufactured by LeaderTech Inc. It features a flat saddle bead design with an internal diameter of 6.40 mm (0.251 inches) and external dimensions of 13.60 mm width by 6.90 mm height. The component provides an impedance of 45 Ohms at a test frequency of 100 MHz. It is constructed from material designated as type 28 and is supplied in bulk packaging without adhesive.

Feature Summary

• Hinged snap-on design for easy installation around cables
• Flat saddle bead geometry for secure cable retention
• No adhesive backing required for mounting

Applications

• General-purpose EMI suppression on single cables
• Cable bundle noise reduction
• High-impedance signal line filtering

Procurement Notes

Verify the specific impedance value of 45 Ohms at 100 MHz against your system requirements. Confirm that the 6.40 mm inner diameter accommodates the target cable or connector size. Ensure the hinged mechanism is suitable for the intended application environment, as it lacks adhesive fixation.

Selection Notes

Select this component when a non-adhesive, reusable ferrite solution is required for cables up to 6.40 mm in diameter. The 45 Ohm impedance at 100 MHz makes it suitable for general broadband noise suppression. Consider the flat profile if space constraints exist alongside the cable.

Part Context

This part belongs to the SB28 series of saddle bead ferrites from LeaderTech. These components are categorized under EMI gaskets, sheets, absorbers, and shielding products. They are designed for simple, effective noise control on individual wires or small bundles without permanent attachment methods.

Replacement Considerations

Cross-reference with other LeaderTech SB28 series parts for similar dimensions but different impedances. Verify compatibility with alternative manufacturers offering 6.40 mm ID hinged ferrites with comparable 45 Ohm @ 100 MHz specifications.
