28B0395-000

Overview

The 28B0395-000 is a solid, free-hanging ferrite cable core manufactured by Laird-Signal Integrity Products. It utilizes Material 28 to provide an impedance of 83 Ohms at 100 MHz. The component features a circular design with an inner diameter of 5.97 mm (0.235 inches), an outer diameter of 10.01 mm (0.394 inches), and a length of 6.17 mm (0.243 inches). It is classified as a round cable core suitable for suppressing electromagnetic interference on wires.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Utilizes Material 28 composition for specific frequency attenuation
• Circular geometry accommodates standard wire gauges

Applications

• Electromagnetic interference suppression on power cables
• Signal line noise filtering in electronic assemblies
• Cable harness protection in industrial equipment

Procurement Notes

Verify the exact part number suffix to confirm material composition and impedance characteristics, as variations exist within the series. Confirm RoHS3 compliance status for current production runs. Check manufacturer lead times, which may vary based on volume requirements. Ensure storage conditions align with general ferrite handling guidelines to maintain physical integrity prior to assembly.

Selection Notes

Select this component when a through-hole cable solution is required rather than a surface-mount bead. The 5.97 mm inner diameter dictates the maximum cable thickness it can accommodate. Material 28 selection should be validated against the specific noise spectrum of the application to ensure adequate attenuation at the target frequencies.

Part Context

This component belongs to the 28B series of ferrite cable cores from Laird-Signal Integrity Products. These parts are distinct from chip ferrite beads, offering a non-soldered, clamped solution for existing cabling. The series provides various impedance values and dimensions to suit different cable sizes and noise profiles.

Replacement Considerations

Direct substitutes must match the 83 Ohm @ 100 MHz impedance and 5.97 mm inner diameter. Verify that alternative materials offer comparable performance at the operating frequency. Physical clearance around the cable must accommodate the 10.01 mm outer diameter.
