WBC3/R-3S4

Overview

The Ferroxcube WBC3/R-3S4 is a radial leaded ferrite bead designed for wideband chokes and EMI suppression. It utilizes the proprietary 3S4 soft ferrite material, which provides high impedance characteristics across a broad frequency spectrum. The component features a robust radial construction suitable for through-hole mounting on printed circuit boards. Its primary function is to attenuate high-frequency noise and electromagnetic interference in electronic circuits without significantly affecting the desired signal frequencies.

Feature Summary

• High impedance performance for effective wideband noise attenuation
• Radial leaded configuration for secure PCB mounting
• Constructed with specialized 3S4 soft ferrite material

Applications

• Electromagnetic interference (EMI) suppression in power supplies
• Wideband choke applications in communication equipment
• Noise filtering in consumer electronics and industrial control systems

Procurement Notes

Verify the specific suffix 'Z' if environmental compliance or specific packaging requirements are mandatory, as the base part number may denote standard specifications. Confirm that the radial lead style matches your assembly process. Ensure the 3S4 material grade aligns with your target frequency range for optimal impedance performance. Cross-reference official datasheets for precise electrical limits before finalizing procurement orders.

Selection Notes

Select this component when broad-spectrum noise suppression is required rather than narrow-band filtering. The 3S4 material offers a balanced impedance profile suitable for general-purpose EMI reduction. Consider the physical dimensions of the WBC3/R form factor to ensure adequate clearance on the PCB layout. Evaluate the thermal environment to ensure operation remains within the specified temperature range for stable magnetic properties.

Part Context

This component belongs to the WBC series of radial ferrite beads manufactured by Ferroxcube. The series is engineered for compact EMI suppression solutions. The 'R' designation typically indicates the radial lead style, while '3S4' specifies the ferrite material composition. This product line supports various industries requiring reliable noise control in space-constrained designs.

Replacement Considerations

Direct substitutes must match the radial footprint and 3S4 material impedance curve. Verify that alternative components provide comparable impedance at critical noise frequencies. Ensure mechanical compatibility with existing PCB holes and soldering profiles. Consult manufacturer cross-reference lists for validated equivalents.
