SB28B2027

Overview

The SB28B2027 is a hinged ferrite core manufactured by Leader Tech Inc., designed for EMI suppression on cables. It features a flat design with an inner diameter of 24.40mm and an impedance of 18 Ohms at 100MHz. The component utilizes Material 28 ferrite composition to provide effective noise reduction. Physical dimensions include a width of approximately 38.1mm, height of 19.05mm, and length of 38.1mm. It is packaged in bulk quantities and complies with RoHS3 standards.

Feature Summary

• Hinged snap-lock design allows for easy installation and removal around existing cable bundles without disconnecting wires.
• Utilizes Material 28 ferrite composition to provide high impedance characteristics for effective electromagnetic interference suppression.
• Flat saddle bead geometry accommodates larger diameter cables or multiple bundled conductors within the central aperture.

Applications

• Suppression of electromagnetic interference on large-diameter power cables
• Noise filtering for data communication cable bundles
• EMI mitigation in industrial equipment wiring harnesses

Procurement Notes

Verify the specific impedance value and physical dimensions against your application requirements before ordering. Confirm that the hinged mechanism operates correctly for your maintenance needs. Check for RoHS3 compliance if environmental regulations apply to your deployment. Ensure the inner diameter is sufficient for the target cable bundle size.

Selection Notes

Select this model when a non-invasive solution for large cables is required. The hinged design eliminates the need to thread cables through solid cores. Material 28 offers a balance of permeability and resistivity suitable for general EMI applications. Compare the 18 Ohm impedance rating against the frequency spectrum of the noise you intend to suppress.

Part Context

This component belongs to the SB28 series of ferrite cores from Leader Tech Inc. The series includes various sizes and impedances tailored for different cable diameters and noise profiles. These cores are widely used in electronics manufacturing and maintenance for retrofitting EMI protection onto existing assemblies.

Replacement Considerations

SB28B2027 is the primary part number. Verify compatibility with any direct substitutes based on identical impedance and dimensional specifications. Ensure replacement parts maintain the same hinged design and material composition for equivalent performance.
