28B0474-000

Overview

The 28B0474-000 is a solid free-hanging ferrite core manufactured by Laird-Signal Integrity Products. It features an inner diameter of 4.50mm and an outer diameter of 12.00mm, with a length of 3.55mm. Designed for cable applications, this component helps reduce electromagnetic interference (EMI) and high-frequency noise. The product is RoHS3 compliant and classified under ECCN EAR99.

Feature Summary

• Solid free-hanging design for easy installation on cables
• Constructed from ultra-thin mixtures of iron, nickel, and zinc oxides
• Effective reduction of electromagnetic interference and high-frequency noise

Applications

• Cable EMI suppression
• High-frequency noise reduction in wiring harnesses
• Signal integrity enhancement for electronic interconnects

Procurement Notes

Verify the specific ferrite material composition and impedance characteristics against your application requirements before procurement. Confirm that the physical dimensions, particularly the inner diameter of 4.50mm, are compatible with the target cable size. Ensure compliance with RoHS3 standards if required by your project specifications.

Selection Notes

Select this component when a solid, non-split ferrite core is needed for permanent cable treatment. Consider the inner diameter to ensure a snug fit on the cable without excessive force. Evaluate the frequency range of the noise to be suppressed, as different ferrite materials offer varying performance across spectra.

Part Context

This part belongs to the 28x series of ferrite cable cores from Laird Connectivity. These cores are typically used in conjunction with other EMI suppression solutions to protect sensitive electronics from external interference and prevent emitted noise from affecting nearby components.

Replacement Considerations

Check for alternative ferrite cores with similar inner and outer diameters. Verify that any substitute material offers comparable permeability and impedance characteristics at the target frequencies.
