SB28B1251

Overview

The SB28B1251 is a hinged ferrite core designed for cable bundle EMI suppression. It features an adhesive base for secure mounting and a round shape with a 19.1 mm inside diameter. The component measures 35.1 mm in outside length, 41.7 mm in outside width, and 22.2 mm in outside height. It belongs to the SB28 series and is supplied in bulk packaging.

Feature Summary

• Hinged snap-on design allows installation around existing cables without disconnection
• Integrated adhesive base provides permanent mounting on flat surfaces
• Round core geometry accommodates various cable bundle diameters

Applications

• EMI/RFI suppression for multi-conductor cable bundles
• Shielding of electronic interconnect wiring
• Noise reduction in circuit board interconnects

Procurement Notes

Verify the specific manufacturer designation, as Leader Tech and FerriShield both list this part number. Confirm RoHS compliance status through official documentation before integration. Ensure the adhesive base requirement matches the application surface conditions. Check factory pack quantities for inventory planning purposes.

Selection Notes

Select this model when a pre-assembled ferrite solution with mounting capability is required. The hinged design simplifies retrofitting onto existing harnesses. Compare internal diameter specifications against target cable bundle sizes to ensure proper fit. Consider the adhesive base as a fixed feature rather than an optional accessory.

Part Context

This component falls under the Leader Tech SB28 series of saddle beads and ferrite cores. It is categorized within EMI gaskets, sheets, absorbers, and shielding products. The product serves as a passive electromagnetic interference mitigation device for high-frequency noise attenuation in electronic assemblies.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative ferrite cores based on impedance characteristics and physical dimensions if substitution is necessary.
