28B0315-100

Overview

The 28B0315-100 is a solid ferrite core manufactured by Laird-Signal Integrity Products, designed for electromagnetic interference suppression on cables. It features a circular geometry with free-hanging mounting capabilities. The component exhibits an impedance of 158 Ohms at 100 MHz and utilizes material grade 28. Physical dimensions include an inner diameter of 0.125 inches (3.17 mm), an outer diameter of 0.315 inches (8.00 mm), and a length of 0.396 inches (10.06 mm).

Feature Summary

• Solid construction provides consistent magnetic properties for broadband noise attenuation.
• Free-hanging design allows installation without mechanical fixtures or adhesives.
• Circular profile accommodates various cable diameters within the specified bore size.

Applications

• Suppression of common-mode noise on power supply cables.
• EMI filtering for signal transmission lines in electronic assemblies.
• Noise reduction on interconnect cables in industrial equipment.

Procurement Notes

Verify the specific impedance requirement against application needs, as this model specifies 158 Ohms at 100 MHz. Confirm that the inner diameter of 3.17 mm matches the target cable outer diameter to ensure proper fit. Check RoHS3 compliance status if required by project specifications. Ensure the solid core design aligns with assembly processes compared to split-core alternatives.

Selection Notes

Select this component when high impedance at 100 MHz is required for cable noise suppression. The 3.17 mm inner diameter suits medium-gauge cables. Consider the solid form factor for permanent installations where disassembly is not needed. Compare performance against other material grades if frequency characteristics differ from standard applications.

Part Context

This part belongs to the 28B series of ferrite cores from Laird-Signal Integrity Products. These components are categorized under cable ferrites and are distinct from surface-mount chip beads like the HI or MI series. The series focuses on through-hole or free-hanging solutions for cable management and EMI control rather than PCB-mounted filtering.

Replacement Considerations

HI1206T500R-10 is listed as a direct replacement for the discontinued HI1206T500R-00, but it is a surface-mount chip bead and not a functional substitute for the 28B0315-100 cable core. No verified direct substitute part numbers are available for the 28B0315-100 in the provided documentation.
