High Frequency Distributed Gap Inductor Cores Technical Bulletin      
                   
MICROLITE® Toroidal Cores are manufactured with METGLAS® amorphous alloy 2605SA1 ribbon. Their unique combination of high saturation flux density and low loss make them the first choice for all energy storage applications, enabling the designer to achieve both size an system cost
reduction.

Applications

• SMPS output inductors
• Flyback transformers
• Differential input inductors
• PFC inductors
• VRM inductors

Benefits

• High saturated flux density
• Significant size reduction
• Low core loss
• Extended bias capability
• Fewer turns due to higher permeability
