Feature Summary

• Provides effective EMI suppression and signal filtering
• Constructed from high-performance 3C90 ferrite material
• Features a compact cylindrical package design

Applications

• Electromagnetic interference suppression
• Signal filtering in electronic circuits
• Noise attenuation on cables

Procurement Notes

Verify the specific impedance value and frequency rating against the official datasheet to ensure compatibility with the target application's noise spectrum. Confirm that the physical dimensions align with the available mounting space. Check for RoHS compliance status if required by regulatory standards. Ensure the supplier provides genuine Ferroxcube components to guarantee material properties.

Selection Notes

Select this component when a low-profile cylindrical ferrite bead is required for broadband noise suppression. The 3C90 material offers high permeability suitable for general-purpose EMI filtering. Consider the 28 Ohm impedance characteristic at 100 MHz to determine effectiveness against specific interference frequencies. Evaluate the physical size constraints to ensure the 5.1 mm diameter fits the assembly requirements.

Part Context

This part belongs to the Ferroxcube BD series of ferrite beads, which are widely used for common-mode noise suppression. The 3C90 material designation indicates a specific manganese-zinc ferrite formulation optimized for high permeability and low core losses at frequencies up to several megahertz. This series complements other Ferroxcube magnetic components like U cores and toroids for comprehensive power electronics and signal integrity solutions.

Replacement Considerations

Cross-reference with other cylindrical ferrite beads offering similar impedance characteristics at 100 MHz. Verify that alternative materials provide comparable permeability and saturation levels. Ensure mechanical dimensions match the existing footprint to avoid rework.
