Product Description
1K101 (2605SA1-type, Fe-Si-B) iron-based amorphous ribbon is designed for distribution transformer cores and inductors. It offers high saturation flux density (~1.2–1.56 T) with very low core loss. The no-load loss of distribution transformers is 1/3 to 1/5 that of grain-oriented silicon steel, delivering significant energy savings. Ribbon thickness is 0.02–0.03mm.
