Optional treatments of finished core:
（1）Uncut, non-impregnated.
（2）Uncut, lightly impregnated with epoxy varnish.
（3）Cut, fully impregnated with epoxy resin.
（4）Multiple-cut, fully impregnated with epoxy resin.
（5）Assembled with plastic cases [PP, maximum working temperature 110℃, thickness 0.4~0.8mm].
（6）Green epoxy coating [maximum working temperature 180℃, thickness 0.20~0.50mm].
（7）Black epoxy painting.
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.
