28B1000-000

Overview

The Laird-Signal Integrity Products 28B1000-000 is a solid, free-hanging ferrite core designed for cable suppression. It features a circular design with an inside diameter of 12.70mm (0.500 inches), an outside diameter of 25.40mm (1.000 inches), and a length of 12.70mm (0.500 inches). The component exhibits an impedance of 151 Ohms at 100MHz. Constructed from material designated as type 28, it is suitable for suppressing electromagnetic interference on round cables.

Feature Summary

• Solid construction provides structural integrity for free-hanging installation on cables.
• Circular geometry accommodates round cable diameters up to the specified inner dimension.
• Material composition optimized for high-frequency noise attenuation in signal integrity applications.

Applications

• Suppression of electromagnetic interference on power cables
• Noise reduction on data transmission lines
• Cable assembly EMI filtering

Procurement Notes

Verify the specific impedance requirements against the application frequency spectrum before procurement. Confirm that the cable diameter falls within the 12.70mm inner diameter tolerance to ensure proper fit. Check RoHS3 compliance status if required by project specifications. Ensure the solid core design aligns with mechanical constraints for free-hanging mounting scenarios.

Selection Notes

Select this component when a large bore size is necessary for thick cables requiring significant magnetic path cross-section. The 151 Ohm impedance at 100MHz indicates suitability for specific high-frequency noise profiles. Consider the physical dimensions to verify clearance availability in the final assembly compared to smaller series options.

Part Context

This part belongs to the 28B series of cable ferrites manufactured by Laird-Signal Integrity Products. The series utilizes material formulation 28, which defines the magnetic properties and frequency response characteristics. These components are distinct from chip beads or split cores, offering a permanent solution for fixed cable assemblies.

Replacement Considerations

Direct substitutes include other 28B series cores with similar impedance curves but different dimensions, such as the 28B0395-000 for smaller cables. Verify that any replacement maintains the required inner diameter and impedance profile at the target operating frequency.
