The Ferroxcube WBC3/R-3S4-Z is a radial ferrite bead designed for wideband chokes and EMI suppression. It utilizes 3S4 soft ferrite material, offering high impedance characteristics suitable for noise filtering in electronic circuits. The component features a radial leaded package, facilitating through-hole mounting on printed circuit boards. Its design targets effective attenuation of electromagnetic interference across specific frequency ranges, ensuring signal integrity in sensitive applications.
Verify the complete part number including the suffix -Z against official Ferroxcube documentation to ensure material and packaging compliance. Confirm that the 3S4 material grade matches the specific impedance requirements of the target application. Cross-reference with authorized distributors to validate authenticity and traceability of the component batch.
Select this component based on the required impedance magnitude at the target noise frequency. Ensure the radial form factor fits the mechanical constraints of the assembly. Evaluate the thermal stability of the 3S4 material against the operating environment. Compare alternative materials if higher or lower impedance thresholds are necessary for the specific EMI profile.
This component belongs to the WBC series of ferrite beads from Ferroxcube, a division of Magnetics International. The series is recognized for providing reliable magnetic components for EMI control. The WBC3/R variant specifically denotes the physical size and radial lead configuration within this product line, supporting various ferrite material grades for different frequency responses.
Direct substitutes include other WBC3/R variants with different material grades such as WBC3/R-4B1-Z or WBC3/R-4S2-Z, provided the impedance characteristics align with the circuit requirements. Verify that any replacement maintains the same radial footprint and electrical parameters.
