28B0375-000

Overview

The Laird-Signal Integrity Products 28B0375-000 is a solid, free-hanging ferrite core designed for cable EMI suppression. It features a cylindrical shape with an internal diameter of 0.200 inches (5.08mm), an external diameter of 0.375 inches (9.53mm), and a length of 0.410 inches (10.41mm). The component utilizes Material 28, providing an impedance of 125 Ohms at 100MHz. It is classified as a round cable core suitable for broadband filtering applications.

Feature Summary

• Solid construction provides stable magnetic properties without moving parts
• Free-hanging design allows easy installation onto existing cables
• Material 28 composition offers specific high-frequency attenuation characteristics

Applications

• Suppression of unintended signals on cables or wires
• Broadband EMI filtering for electronic interconnects
• Reduction of electromagnetic interference emissions from wire harnesses

Procurement Notes

Verify the exact part number against manufacturer documentation to ensure correct impedance and dimensional specifications. Confirm material grade and RoHS compliance status prior to integration. Check for updated datasheets as product specifications may evolve. Ensure compatibility with cable diameters before finalizing procurement decisions.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. The 5.08mm inner diameter dictates the maximum cable size it can accommodate. Consider the 125 Ohm impedance at 100MHz for target noise frequency ranges. Evaluate space constraints given the 10.41mm length requirement.

Part Context

This component belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. It is distinct from hinged or split-core variants like the 28B0375-310, which offer different mechanical mounting options. The solid design ensures consistent performance without the air gaps associated with snap-on cores.

Replacement Considerations

Direct substitutes include other solid ferrite cores with matching 5.08mm ID and similar impedance profiles. Verify that alternative materials provide equivalent attenuation curves for the specific application frequencies.
