The transformers in switch mode power supply (SMPS) are important components, which require low iron core loss. Xianyu’s nanocrystalline cores have high premeability and low coercivity, as we wind them by very thin ribbon, about 0.018~0.025mm. Accoring to different method of annealing process, we can get different Br/Bs ratio, range from 0.2 to 0.85. The normal encapsulation is plastic case or epoxy resin coating, both are suitable for direct winding.
