The Fe-based amorphous alloy has a long-range disordered, short-range ordered atomic structure, and has no defects such as dislocations and grain boundaries in the crystal, so it has high strength and hardness. However, restricted by the amorphous formation temperature, preparation process and room temperature brittleness, the current critical dimension of iron-based amorphous alloys is only at th...

Common Mode Chokes When we said a common mode choke, it means it was wound both line and neutural windings on a single core. Since the noise would be common mode noise usually, the way to lower (if not eliminate) the unwant noise frequencies is to use a common mode choke As below picture show us details of Common-Mode Signals Defined: Such signals can arise from one or more of the following source...
