FeSi Toroid Core is specialized transformer cores made from FeSi (iron-silicon) material and shaped in a toroidal configuration. This design allows for a closed-loop magnetic path, enhancing magnetic flux containment and reducing electromagnetic interference. FeSi Toroid Cores offer high efficiency and low core losses, making them suitable for applications requiring precise control of magnetic fields, such as power supplies, audio equipment, and telecommunications devices. Their compact and symmetrical design also contributes to space-saving and improved performance in electronic circuits.
Two series of toroidal core
A series
A round core wound by automatic machines with one continuous tape of CRGO silicon steel and annealed in a tunnel furnace under the protection of inert gases.
Material thickness: 0.30mm, 0.27mm, 0.23mm, 0.10mm, 0.08mm and 0.05mm.
B series
B series core commonly used as a replacement of EI and other toroidal transformers with lower magnetic loss requirement.
Material thickness: 0.30mm, 0.27mm, 0.23mm
