WBC2.5/A-4B1-Z

Overview

The WBC2.5/A-4B1-Z is a signal line ferrite bead manufactured by Ferroxcube, designed for electromagnetic interference suppression in electronic circuits. It utilizes the proprietary 4B1 ferrite material to provide high impedance characteristics across specific frequency ranges. The component features an axial package with radial bend mounting options, suitable for through-hole applications. Key electrical specifications include an impedance of 700 Ohms at 180 MHz and 700 Ohms at 75 MHz, ensuring effective noise attenuation for single-line signal paths.

Feature Summary

• Constructed with Ferroxcube 4B1 ferrite material for optimized magnetic properties
• Designed as a wideband choke for single-signal line EMI suppression
• Features axial form factor with radial bend capability for flexible PCB mounting

Applications

• Signal line filtering in consumer electronics
• EMI suppression in industrial control systems
• Noise reduction in communication equipment interfaces

Procurement Notes

Verify the exact suffix designation when ordering, as variations such as -Z or -F may indicate different packaging or compliance standards. Confirm the specific impedance tolerance requirements against the official datasheet before finalizing procurement. Ensure that the axial/radial bend physical dimensions align with the target printed circuit board layout constraints to prevent mechanical stress during assembly.

Selection Notes

Select this component based on its 4B1 material composition, which offers distinct permeability characteristics compared to other series like 3S4. The choice depends on the required impedance profile at target operating frequencies, specifically around 75 MHz and 180 MHz. Evaluate the physical size constraints, noting the 6 mm diameter and 10 mm length, to ensure compatibility with the available space on the assembly board.

Part Context

This part belongs to the WBC2.5/A series of ferrite beads from Ferroxcube. It is distinct from similar parts like WBC1.5/A-4B1-Z due to its specific dimensional and electrical parameters. The 4B1 material designation indicates a specific ferrite formulation tailored for broadband noise suppression, differentiating it from materials used in power chokes or other specialized magnetic components within the manufacturer's portfolio.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Similar parts in the WBC2.5/A series with different material grades, such as those using 3S4 material, offer different impedance curves and should be evaluated carefully. Cross-referencing the exact impedance-frequency curve is essential when considering alternative components.
