28B0375-100

Overview

The 28B0375-100 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products, designed for broadband EMI suppression. It exhibits an impedance of 154 ohms at 100 MHz and is constructed from material grade 28. The component features a cylindrical shape with an inner diameter of 0.200 inches (5.08 mm) and an outer diameter of 0.375 inches (9.53 mm). Its total length measures 0.570 inches (14.48 mm). This cable ferrite supports effective reduction of both common and differential mode electromagnetic interference in signal and power lines.

Feature Summary

• Provides broadband EMI filtering capabilities for cables
• Solid construction ensures stable performance across frequencies
• Free-hanging design allows easy installation on existing wiring

Applications

• Suppression of common mode noise in data cables
• Reduction of differential mode interference in power lines
• EMI mitigation in industrial communication interfaces

Procurement Notes

Verify the specific impedance value required for your application, as some sources cite 154 ohms while others may reference different test conditions or older revisions. Confirm that the physical dimensions, particularly the 5.08 mm inner diameter, match the cable bundle size. Ensure compliance with current environmental regulations, noting that RoHS status should be checked against the latest manufacturer documentation before final procurement.

Selection Notes

Select this component when a non-inducted, high-impedance solution is needed for broadband noise suppression without altering circuit inductance significantly. The solid core design is preferred over split cores for permanent installations where vibration resistance is critical. Ensure the cable diameter fits within the 5.08 mm inner diameter constraint to maintain proper magnetic coupling efficiency.

Part Context

This part belongs to the 28B series of cable ferrites from Laird-Signal Integrity Products. These components are engineered for general-purpose EMI filtering applications where standard impedance characteristics are sufficient. The 28B series utilizes specific ferrite formulations optimized for broad frequency coverage, making them suitable for diverse electronic environments requiring reliable noise attenuation.

Replacement Considerations

Direct substitutes must match the 154 ohm @ 100 MHz impedance and 5.08 mm inner diameter. Verify that alternative parts offer comparable material properties for similar frequency response characteristics. Ensure mechanical compatibility with existing mounting constraints if space is limited.
