28B0375-300

Overview

The 28B0375-300 is a solid, free-hanging cylindrical ferrite core manufactured by Laird-Signal Integrity Products. It provides broadband EMI suppression for cables and wires. The component exhibits an impedance of 194 Ohms at 100 MHz. Physical dimensions include an inner diameter of 0.200 inches (5.08 mm), an outer diameter of 0.375 inches (9.53 mm), and a length of 0.750 inches (19.05 mm). It utilizes Material 28 for its magnetic properties.

Feature Summary

• Solid construction designed for free-hanging installation on cables
• Broadband cylinder design effective for reducing common and differential mode EMI
• Utilizes Material 28 composition for specific frequency attenuation

Applications

• Cable and wire EMI filtering
• Reduction of common mode noise
• Reduction of differential mode noise

Procurement Notes

Verify the exact part number against manufacturer documentation to ensure correct material grade and physical dimensions. Confirm that the inner diameter accommodates the target cable size without excessive clearance. Check RoHS compliance status if required by specific project regulations. Ensure storage conditions maintain component integrity prior to assembly.

Selection Notes

Select this component when broadband suppression is required for cables with diameters up to 5.08 mm. The solid design allows for easy sliding onto existing cables during assembly or retrofitting. Consider the 194 Ohm impedance at 100 MHz to ensure adequate attenuation for the specific noise frequencies present in the application environment.

Part Context

This part belongs to the 28B series of ferrite cores from Laird-Signal Integrity Products. These components are categorized as cable ferrites intended for electromagnetic interference suppression. The series offers various dimensions and impedance characteristics to suit different cable sizes and frequency requirements.

Replacement Considerations

Direct substitutes may include other 28B series cores with similar dimensions, such as 28B0375-100 or 28B0375-310, provided their impedance values and physical sizes match the design constraints. Verify compatibility before substitution.
