What is a Inductor?
The inductor also called for coil, choke, or reactor. Is a passive component with two two-terminal, designed to resist changes in current.
An inductor is an electronic component that can convert electrical current into a magnetic field. It typically consists of a winding of wire wrapped around a magnetic core. When a current flows through the winding, it produces a magnetic field, and vice versa, when the magnetic field changes, it also produces a current. The function of an inductor can be to convert current into a magnetic field or to convert a magnetic field into current. Additionally, inductors can be used in filters to reduce noise in circuits. In electronic products such as power supplies and audio equipment, inductors play an important role. Inductors can be used to regulate current in circuits, control signal transmission, switch current, receive frequency signals, or stabilize voltage, among other applications. To meet different requirements, inductors also vary in structure and can be roughly classified into four types: 1. Shielded inductors, 2. Semi-shielded inductors (molded inductors), 3. Unshielded (non-shielded) inductors, 4. Common-mode inductors.
