Material:
High-quality CRGO steels with the characteristics of low iron-loss and high permeability in thickness of 0.05mm, 0.23mm, 0.27mm, and 0.3mm.
Characteristic:
It is toroidal and wound in the same direction of closed flux path. No magnetic flux leakage. It has the best magnetic performance. It is easy and high-efficiency for coil winding with the toroidal winding machine.
Application:
The toroidal core is widely used in 50Hz and 400Hz transformers, current transformers, reactors, chokes, and other magnetic components of electronic equipment.
