BD5.1/2/4-4S2

Overview

The Ferroxcube BD5.1/2/4-4S2 is a cylindrical ferrite bead designed for electromagnetic interference suppression. It utilizes the 4S2 soft ferrite material, which is specified for wideband applications based on impedance characteristics. The component features an inner diameter of 2mm and a length of 4mm. Its nominal impedance at 100MHz is 21 ohms. These physical dimensions correspond to the BD5.1/2/4 core geometry.

Feature Summary

Cylindrical form factor suitable for through-hole mounting
Wideband EMI suppression capability using 4S2 material
Defined impedance profile for noise filtering

Applications

Line output transformers
General EMI suppression circuits
Power supply noise filtering

Procurement Notes

Verify the specific suffix (4S2) against the manufacturer's current datasheet to confirm material properties and impedance specifications. Ensure the physical dimensions match the required PCB footprint or wire gauge. Cross-reference with official Ferroxcube documentation to distinguish between similar part numbers like BD5.1/2/4-3S1 which may have different electrical characteristics.

Selection Notes

Select this component when wideband noise suppression is required in power electronics. The 4S2 material offers specific impedance characteristics suitable for high-frequency attenuation. Consider the 2mm inner diameter for wire compatibility. Evaluate the 21 ohm impedance at 100MHz against the target noise frequency spectrum to ensure effective filtering performance.

Part Context

This part belongs to the Ferroxcube line output transformer accessory series. It is categorized as a cylindrical ferrite bead used for common mode choke applications. The 4S2 designation indicates the specific ferrite composition optimized for wideband performance. It complements other components in signal integrity management.

Replacement Considerations

BD5.1/2/4-3S1 shares identical physical dimensions but utilizes 3S1 material with potentially different impedance characteristics. Verify electrical equivalence before substitution. No other direct substitutes are confirmed in public documentation.
