28B0394-000

Overview

The 28B0394-000 is a solid, free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It utilizes Material 28 to provide electromagnetic interference filtering with an impedance of 86 Ohms at 100MHz. The component features a round design with an inner diameter of 5.00mm (0.197 inches), an outer diameter of 10.00mm (0.394 inches), and a length of 5.00mm (0.197 inches). It is currently in production and complies with RoHS3 standards.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Material 28 composition optimized for high-frequency noise suppression
• Round geometry facilitates easy sliding onto wires without specialized tools

Applications

• Suppression of common-mode noise on data cables
• EMI filtering for power supply lines
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific material grade and impedance tolerance against the official datasheet before integration. Confirm that the inner diameter accommodates the target cable bundle diameter with appropriate clearance. Ensure compliance with project-specific environmental regulations such as RoHS3 requirements.

Selection Notes

Select this component when a fixed-geometry ferrite core is required for cables up to 5.00mm in diameter. The Material 28 formulation is suitable for applications targeting noise reduction around 100MHz. Consider the solid design for permanent installations where adjustable clamping is unnecessary.

Part Context

This part belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. It shares the same outer dimensions and mounting style as adjacent variants but differs in inner diameter and impedance characteristics due to its specific material formulation and bore size.

Replacement Considerations

Direct substitutes include parts with identical 5.00mm inner diameter and similar impedance profiles. Verify that alternative materials offer comparable performance at the target frequency range. Ensure mechanical fit remains consistent with existing cable assemblies.
