WBC1.5/1.5/A-3S4-Z

Overview

The Ferroxcube WBC1.5/1.5/A-3S4-Z is a ferrite core from the WBC series, utilizing 3S4 material composition. It features an E-core geometry with specific effective dimensions defined by Lef and Aef parameters. The component provides an inductance factor (AL) of 110 nH/turns². At 1 MHz, it exhibits an impedance magnitude (|Z|) of at least 800 Ohms. This design supports high-frequency magnetic applications requiring stable permeability and low loss characteristics typical of the 3S4 material grade.

Feature Summary

• Utilizes 3S4 soft ferrite material for optimized high-frequency performance
• E-shaped core geometry facilitates efficient winding and assembly
• Provides high impedance magnitude at 1 MHz for effective noise suppression
• Defined AL value ensures predictable inductance in circuit designs

Applications

• High-frequency power transformer cores
• Common mode choke inductors
• EMI suppression components in switching power supplies
• Inductor cores for RF circuits

Procurement Notes

Verify the specific material grade suffix matches the required frequency response. Confirm physical dimensions against mechanical constraints. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any specific handling requirements regarding ceramic fragility during assembly processes.

Selection Notes

Select this model when high impedance at 1 MHz is critical for noise filtering. The 3S4 material offers a balance of permeability and loss characteristics suitable for frequencies above 100 kHz. Compare AL values with alternative materials if precise inductance tuning is required. Consider the core window area for wire gauge selection based on current ratings.

Part Context

This component belongs to the WBC series of ferrite cores manufactured by Ferroxcube. The series includes various sizes and material grades such as 4B1 and 4S2. The WBC1.5/1.5/A designation indicates the specific core size and shape within the product family. These cores are widely used in electronic components manufacturing for magnetic circuit construction.

Replacement Considerations

Direct substitutes include other WBC1.5/1.5/A variants with different materials like 4B1 or 4S2 if impedance profiles differ. Cross-reference with similar E-core sizes from other manufacturers ensuring identical Lef, Aef, and AL values. Verify that replacement materials meet the same thermal and frequency stability requirements.
