Procurement Notes

Verify the specific impedance value required for your application, as sources indicate variations between 146 Ohms and 195 Ohms at 100 MHz for this part number. Confirm the physical dimensions match your cable diameter requirements. Ensure compliance with RoHS3 regulations if applicable to your manufacturing process. Check the manufacturer datasheet for precise material properties and frequency response characteristics before finalizing procurement.

Selection Notes

Select this component when a solid, non-hinged ferrite core is needed for permanent cable treatment. The Material 28 composition offers specific permeability characteristics suitable for broadband noise suppression. Ensure the cable diameter fits within the 0.140-inch inner diameter specification. Consider the 195 Ohm impedance rating at 100 MHz against the target noise frequencies to ensure adequate attenuation performance for the specific EMI environment.

Part Context

This ferrite core is part of Laird-Signal Integrity Products' 28B series, which focuses on cable-based EMI suppression solutions. The series includes various materials and geometries to address different noise profiles. The 28B0473-000 specifically targets applications requiring robust, solid-core filtering without the need for hinged or split designs, providing a compact solution for integrating noise suppression directly onto existing cable assemblies.

Replacement Considerations

Direct substitutes may include other solid ferrite cores from Laird with similar Material 28 composition and comparable impedance values. Verify that alternative parts maintain the same inner diameter of 0.140 inches to ensure fitment. Cross-reference impedance specifications at 100 MHz to confirm equivalent noise suppression capabilities. Ensure any replacement also meets RoHS3 compliance requirements.
