BD3/1/10-4S2

Overview

The Ferroxcube BD3/1/10-4S2 is a ferrite core assembly designed for high-frequency transformer and inductor applications. It consists of two BD3/1 halves with a specified effective magnetic path length (le) of 10 mm and an effective cross-sectional area (Ae) of 10 mm². The material designation '4' indicates the use of Ferroxcube's specific soft ferrite composition optimized for low loss at operating frequencies typically above 10 kHz. The 'S2' suffix denotes the presence of pre-applied adhesive or specific mounting features to facilitate secure assembly in printed circuit board environments.

Feature Summary

• Optimized soft ferrite material composition for reduced core losses in high-frequency switching applications
• Integrated adhesive or mounting configuration for reliable PCB attachment and mechanical stability
• Standardized geometry ensuring consistent magnetic performance across production batches

Applications

• High-frequency flyback transformers
• Common mode chokes for EMI suppression
• Forward converter magnetics

Procurement Notes

Verify the exact material grade and adhesive specifications against the latest manufacturer datasheet, as product revisions may alter surface treatments or material properties. Confirm that the S2 suffix corresponds to the required mounting method for your specific assembly process. Ensure compatibility with your winding equipment regarding bobbin fitment if applicable. Request certification documents to validate material consistency for critical electromagnetic interference compliance testing.

Selection Notes

Select this component based on its specific Ae and le values which determine the inductance factor (Al). Ensure the selected ferrite material grade meets the saturation flux density requirements of your circuit design. Consider the thermal characteristics of the material relative to your expected operating temperature range. Validate that the physical dimensions fit within the constrained space of your target enclosure without compromising safety clearances.

Part Context

This part belongs to the BD series of split ferrite cores manufactured by Ferroxcube. These cores are widely used in power electronics due to their standardized dimensions and availability in various material grades. The BD3 size represents a compact form factor suitable for medium-power applications where space efficiency is prioritized alongside magnetic performance.

Replacement Considerations

Direct substitutes must match the BD3/1 geometry and equivalent magnetic properties. Check for alternative manufacturers offering identical dimensional tolerances and comparable permeability curves. Verify that any replacement maintains the same Al value tolerance to ensure circuit stability.
