Toroidal inductors are passive components that feature a coil of insulated or enameled wire wound on a donut-shaped form made of ferrite or powdered iron. Practical and reliable, toroids are used in low-frequency circuit designs that requires large inductances. They are widely used in medical, industrial, nuclear, aerospace audio products, LED driver and vehicle wireless charging,and other electronic applications. If your circuit design requires a quality toroidal inductor, find them from leading manufacturers, at Future Electronics.
