toroidal inductor
With its distinctive doughnut-like design, the toroidal inductor is a key component in modern electronic circuitry. It stores energy in its magnetic field primarily, or it effectively filters / blocks specific frequency signals. Technological features of the toroidal inductor include a core made out of magnetic materials like ferrite which increase its performance. Typically, the winding is made of copper wire coiled around that core creates the inductive effect. Toroidal inductors minimize electromagnetic interference (EMI) thanks to their shape and the closed magnetic path. They are greatly efficient and reliable. As a consequence, they are used in power supplies analog circuits as well as digital circuits as required for various electronic devices faint applications.
