The Ferroxcube WBS1.5-5/4.8/10-4B1-Z is a wire-wound band choke belonging to the WBS series, designed for surface-mount applications. It utilizes 4B1 soft ferrite material, which provides high permeability and low core losses suitable for RF and power line filtering. The component features a compact rectangular footprint with defined effective magnetic path length (Lef) and effective cross-sectional area (Aef) parameters specific to its geometry. This construction supports efficient inductance generation while maintaining stability across varying operating conditions.
Verify the complete part number including the material suffix and tolerance code against official Ferroxcube documentation. Confirm that the 4B1 material grade matches the required frequency response and saturation characteristics for the specific circuit application. Ensure compatibility with standard SMT reflow profiles during assembly planning.
Select this component based on the required inductance value and current handling capabilities inherent to the 4B1 material properties. Evaluate the physical dimensions against available PCB real estate constraints. Consider the self-resonant frequency limitations of the wire-wound structure when designing for high-frequency interference mitigation scenarios.
This component is part of the Ferroxcube WBS series, which offers various sizes and material options for surface-mount chokes. The WBS designation indicates a specific band shape optimized for winding, distinguishing it from other core shapes like ER or PQ. It serves as a passive electromagnetic interference suppression element within electronic assemblies.
Direct substitutes must match the exact WBS1.5-5/4.8/10 geometry and 4B1 material specification. Alternative materials may alter inductance and impedance characteristics significantly. Verify dimensional tolerances and terminal configuration compatibility before considering any cross-reference parts.
