Conventional silicon steels are widely used for electrical power apparatus, electrical components of industrial products, and home electronics. However, most silicon steel strips are thicker than 0.20mm and only applied to apparatus operated at industrial frequencies.

The thin silicon steel strips are suitable for being used at higher frequencies. The thickness of the silicon steel strips haVE been reduced to the world's thinnest level, reducing the core loss caused by eddy currents. Combined with the insulation coating technology, the lamination factor is improved.

The thin silicon steel strips improve energy consumption and reduce size in high-frequency reactors, transformers, and motors.

The thin silicon steel strips reduce cost and improve the equipment performance at high frequencies.


Characteristics


■ Low Core Loss

   Low core loss at high frequencies improves equipment efficiency and reduce energy consumption of reactors and transformers.


■ High Permeability

   For shields applications.


■ High Saturation Flux Density

  For downsized high frequency reactors and transformers.

■ Excellent insulation coating

  Excellent insulation property enables ideal stress relief annealing (results).
