28B0375-310

Overview

The 28B0375-310 is a solid cylindrical cable ferrite core manufactured by Laird-Signal Integrity Products. It utilizes Material 28 to provide electromagnetic interference suppression with an impedance of 169 Ohms at 100 MHz. The component features a circular design with an inner diameter of 5.08 mm, an outer diameter of 9.53 mm, and a length of 19.05 mm. It is classified as a cable ferrite intended for free-hanging installation on wires.

Feature Summary

• Solid construction provides structural integrity for broadband EMI filtering applications
• Material 28 composition ensures specific high-frequency noise attenuation characteristics
• Cylindrical geometry allows for easy sliding onto cables without disconnection

Applications

• Suppression of unintended signals on power cables
• Filtering emissions from signal wires in electronic assemblies
• Broadband EMI mitigation on harnesses within equipment enclosures

Procurement Notes

Verify the exact part number against manufacturer documentation to confirm Material 28 specification and dimensional tolerances. Ensure compatibility with cable diameters up to 5.08 mm. Check RoHS3 compliance status in current datasheets as manufacturing standards may evolve. Confirm package type availability through authorized distributors.

Selection Notes

Select this component when solid-core ferrites are required for cables exceeding standard bead dimensions. The 169 Ohm impedance at 100 MHz suits general-purpose noise suppression. Consider the 19.05 mm length for adequate thermal mass and attenuation volume compared to shorter cores.

Part Context

This part belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. The series offers various sizes and materials optimized for different frequency ranges and cable diameters. Material 28 is commonly used for suppressing noise in the tens to hundreds of megahertz range.

Replacement Considerations

Direct substitutes include other Material 28 solid ferrites with matching 5.08 mm inner diameter and similar impedance profiles. Verify that alternative parts maintain the 169 Ohm @ 100 MHz specification and compatible physical dimensions for existing cable routing constraints.
