SB28B0550

Overview

The SB28B0550 is a hinged ferrite core manufactured by Leader Tech Inc., designed for cable electromagnetic interference suppression. It features a snap-on design allowing installation without disconnecting cables. The component utilizes Material 28, providing an impedance of 100 Ohms at 100 MHz. Physical dimensions include an inner diameter of 5.41 mm (0.213 inches), an outer width of 14.00 mm (0.551 inches), and a height of 7.00 mm (0.276 inches). The total length is 28.00 mm (1.102 inches).

Feature Summary

• Hinged snap-on construction enables rapid installation on existing cables.
• Free-hanging configuration allows flexible positioning along wire harnesses.
• Material 28 composition provides specific high-frequency noise attenuation characteristics.

Applications

• Suppression of electromagnetic interference in data communication cables.
• Noise reduction for power supply lines in electronic equipment.
• Cable management and EMI control in industrial control systems.

Procurement Notes

Verify the exact part number suffix to ensure correct material grade and dimensional tolerances. Confirm RoHS compliance status with the supplier, as environmental regulations may vary by region. Check manufacturer documentation for storage conditions and handling precautions to maintain magnetic properties. Ensure compatibility with cable diameters before finalizing procurement orders.

Selection Notes

Select this component when a non-invasive solution for cable shielding is required. The hinged design is preferred over split cores that require tools or permanent modification. Verify that the cable diameter falls within the 5.41 mm inner diameter specification. Consider the 100 Ohm impedance rating at 100 MHz against the target noise frequency spectrum to ensure effective attenuation performance.

Part Context

This component belongs to the SB28 series of saddle beads from Leader Tech Inc. The series offers various sizes and materials tailored for different cable diameters and frequency requirements. The SB28B0550 specifically addresses mid-sized cable applications requiring robust mechanical retention and consistent high-frequency noise suppression.

Replacement Considerations

SB28B0550AB is listed as a parameter-equivalent substitute. Verify that the AB suffix does not alter critical electrical parameters or physical dimensions before substitution. Cross-reference datasheets to confirm identical impedance curves and material specifications.
