Toroidal Magnetic Cores

Yudzhen LLC manufactures Toroidal magnetic cores from electric anisotropic steel of 0.3 mm width.

Toroidal core has an ideal shape for producing a transformer with minimal material consumption. Toroidal magnetic cores are manufactured from electric anisotropic steel TO-ET 3406/3407/3408/3409 of 0.3 mm width. Steel quality ensures low magnetostriction and low stray losses, which practically completely eliminates hum and noise associated with operation of conventional transformers.
