SB28B0617AB

Overview

The SB28B0617AB is a half-bead ferrite core manufactured by LeaderTech, designed for EMI suppression on cables. It features an adhesive bottom mount style and belongs to the SB28 series utilizing material grade 28. The component has a diameter of 0.276 inches (approximately 7 mm) and includes an integrated adhesive backing for secure attachment. This snap-on design allows for easy installation around single round cables without requiring disconnection of the wire harness.

Feature Summary

• Snap-on half-bead design enables rapid installation around existing cable assemblies
• Integrated adhesive backing provides secure mounting without additional hardware
• Utilizes high-permeability ferrite material for effective broadband noise attenuation

Applications

• Suppression of electromagnetic interference on single round cables
• Attenuation of common-mode noise in data transmission lines
• EMI mitigation in compact electronic device wiring harnesses

Procurement Notes

Verify the specific adhesive type and surface compatibility requirements before integration. Confirm that the cable diameter falls within the specified inner diameter tolerance to ensure proper mechanical fit. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the operating temperature range aligns with the ferrite material specifications provided in the official datasheet.

Selection Notes

Select this component when a low-profile, adhesive-mounted solution is preferred over split-clamp designs. The half-bead geometry offers a balance between shielding effectiveness and space constraints. Consider the impedance characteristics at the target frequency of operation. Evaluate the mechanical strength of the adhesive against environmental factors such as vibration or thermal cycling.

Part Context
