28B0672-000

Overview

The 28B0672-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products, designed for broadband electromagnetic interference (EMI) filtering. It exhibits an impedance of 245 Ohms at 100 MHz and features an inside diameter of 8.76 mm (0.345 inches). This component serves as a suppressor for unintended signals on cables or wires, providing effective noise reduction in electronic assemblies without requiring complex mounting hardware.

Feature Summary

• Solid construction provides stable EMI suppression for round cables
• Broadband filtering capability with high impedance at 100 MHz
• Free-hanging design allows flexible installation on various wire diameters

Applications

• Suppression of unintended signals on round cables
• Broadband EMI filtering for wire harnesses
• Noise reduction on power and signal lines

Procurement Notes

Verify the specific impedance value and physical dimensions against the official Laird datasheet to ensure compatibility with target cable diameters. Confirm that the solid core configuration meets the mechanical requirements of the assembly, as snap-on alternatives may be required for serviceability. Check RoHS compliance status for regulatory adherence.

Selection Notes

Select this component when a fixed, non-split ferrite solution is acceptable for permanent installations. The 8.76 mm inner diameter dictates the maximum cable size it can accommodate. Ensure the application does not require frequent disassembly, as solid cores cannot be opened once installed around the conductor.

Part Context

This part belongs to Laird's range of cable ferrites and suppressors. Unlike chip beads used on PCBs, this component targets external cabling. It complements split-core options by offering a potentially more robust mechanical attachment for static applications where hinged access is unnecessary.

Replacement Considerations

Direct substitutes include other solid ferrite cores from Laird with matching 8.76 mm ID and similar impedance characteristics. Verify that alternative brands maintain the same 245 Ohm @ 100 MHz specification to ensure equivalent noise suppression performance.
