The Ferroxcube WBC1.5/1.5/A-3S4 is a wideband choke ferrite core designed for high-frequency noise suppression. It utilizes the proprietary 3S4 magnetic material, which provides high impedance characteristics across a broad frequency spectrum. The component features a specific geometry with an effective length (Lef) and effective area (Aef) optimized for winding applications. At 120 MHz, this core achieves an impedance of at least 300 Ohms, ensuring effective attenuation of electromagnetic interference in demanding electronic circuits.
Verify the exact physical dimensions and material grade against the official Ferroxcube datasheet before procurement. Ensure the 3S4 material specification matches the design requirements for the target frequency range. Confirm that the supplier provides genuine components with traceable documentation to maintain quality standards.
Select this component when high impedance at frequencies around 120 MHz is required. The 3S4 material offers a balance of permeability and resistivity suitable for wideband applications. Consider the physical size constraints and winding compatibility when integrating this core into the final assembly.
This part belongs to the WBC series of wideband chokes from Ferroxcube. The series includes various geometries such as WBC1.5/A and WBC2.5 variants. Each variant is available in different materials like 4B1 or 4S2 to tailor impedance characteristics for specific frequency bands and application needs.
Direct substitutes include other WBC series cores with similar dimensions but different materials, such as WBC1.5/1.5/A-4B1-Z, if impedance profiles differ. Verify cross-compatibility based on specific impedance curves rather than just physical fit.
