28B0999-000

Overview

The 28B0999-000 is a solid cylindrical ferrite core manufactured by Laird-Signal Integrity Products. It provides an impedance of 122 Ohms at 100 MHz and utilizes Material 28. The component features a free-hanging installation type with an inner diameter of 15.49 mm, an outer diameter of 25.40 mm, and a length of 12.70 mm.

Feature Summary

• Solid construction for stable electromagnetic interference suppression
• Free-hanging design allows easy installation over cables without specialized fixtures
• Material 28 composition optimized for high-frequency noise attenuation

Applications

• Cable shielding for high-speed data lines
• Power supply cable noise reduction
• Electromagnetic interference suppression in electronic assemblies

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm physical dimensions and impedance characteristics. Ensure compatibility with cable diameters before integration. Confirm RoHS3 compliance status through current datasheets as regulatory requirements may evolve.

Selection Notes

Select this component when a solid, non-hinged ferrite core is required for cables with an inner diameter near 15.49 mm. Consider the 122 Ohm impedance at 100 MHz for target frequency noise profiles. Evaluate space constraints relative to the 25.40 mm outer diameter and 12.70 mm length.

Part Context

This component belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. These cores are designed for general-purpose electromagnetic interference filtering. The solid design distinguishes it from hinged alternatives, offering a permanent magnetic path around the conductor.
