SB28B0642AB

Overview

The SB28B0642AB is a hinged ferrite core manufactured by Leader Tech Inc., designed for EMI suppression on cables. It features a flat saddle bead design with an internal diameter of 8.10mm (0.319 inches) and an external length of 16.00mm (0.630 inches). The component exhibits an impedance of 30 Ohms at 100MHz and utilizes Material 28. It operates in a free-hanging configuration without adhesive, allowing for easy installation around existing wiring harnesses.

Feature Summary

• Hinged snap-together construction enables rapid installation around cables without disconnection
• Utilizes Material 28 composition for effective high-frequency noise attenuation
• Free-hanging design eliminates the need for mounting hardware or adhesives

Applications

• Suppression of electromagnetic interference on data communication cables
• Noise reduction on power supply lines in electronic assemblies
• EMI mitigation in cable bundles within industrial equipment enclosures

Procurement Notes

Verify the specific suffix AB against the manufacturer's current datasheet to confirm dimensional tolerances and material specifications. Ensure compatibility with the target cable diameter before procurement, as the internal bore size is fixed. Confirm RoHS3 compliance status if required by your assembly standards, and check for any recent design changes that may affect mechanical fit.

Selection Notes

Select this component when a non-permanent, reusable ferrite solution is required for cable management. The hinged design offers advantages over split cores that require tools or permanent cores that necessitate cable removal. Consider the 8.10mm inner diameter constraint to ensure it accommodates the specific cable bundle thickness while maintaining sufficient magnetic coupling for effective noise suppression.

Part Context

This part belongs to the SB28 series of saddle beads from Leader Tech Inc., which are specialized for EMI/RFI filtering. The series includes various sizes and materials tailored for different frequency ranges and cable diameters. The SB28B0642AB specifically targets applications requiring moderate impedance characteristics with convenient access for maintenance or modification.

Replacement Considerations

SB28B0642 is listed as a parameter-equivalent substitute.
