28B0354-000

Overview

The Laird-Signal Integrity Products 28B0354-000 is a solid, free-hanging ferrite core designed for cable and wiring applications. It provides electromagnetic interference suppression with an impedance of 132 Ohms at 100 MHz. The component features a circular design with an internal diameter of 4.50 mm (0.177 inches) to accommodate cables. External dimensions are 9.00 mm in diameter and approximately 6.17 mm in length. It is classified as a passive filter component suitable for surface or free-hanging installation.

Feature Summary

• Solid construction for durable high-frequency noise attenuation
• Free-hanging design allows easy installation on existing cables
• Circular geometry accommodates various wire gauges

Applications

• Cable and wiring EMI filtering
• High-frequency noise suppression in electronic assemblies
• Signal integrity enhancement for data lines

Procurement Notes

Verify the specific impedance value and physical dimensions against the official datasheet before integration. Confirm RoHS compliance status and environmental certifications required for your target market. Ensure the cable diameter falls within the 4.50 mm inner diameter specification to guarantee proper fit and magnetic coupling efficiency.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable treatment. The 132 Ohm impedance at 100 MHz targets specific high-frequency noise bands. Consider the free-hanging form factor for applications where snap-on cores are unsuitable or where higher mechanical stability is needed compared to split designs.

Part Context

This part belongs to the Laird-Signal Integrity Products ferrite core family, specifically engineered for cable management and EMI reduction. It complements other components like the MI1210K600R-10 chip bead by offering a solution for larger cable bundles rather than PCB-mounted traces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite cores based on identical impedance curves and inner diameter specifications.
