nanocrystalline cores

High saturation magnetic induction-Compared with traditional ferrite cores, the transformer volume can be reduced


High permeability-improve efficiency, low excitation power, reduce copper loss


Low coercivity and low iron loss-low temperature rise of transformer, energy saving, low carbon and environmental protection


High Curie temperature-good temperature characteristics, working temperature -40 – 130℃
