Background

Inductors, also known as chokes, reactors, dynamic reactors, and inductors, are components that can convert electrical energy into magnetic energy for storage. The inductor is similar in structure to a transformer, typically having only one winding. The inductor has an inductance that only impedes the change in current, and if the inductor is in a state where no current is passing through it will attempt to impede the flow of current through it when the circuit is closed; if the inductor is in a current passing state, the inductor will try to keep the current unchanged when the circuit is opened. Inductors are typically comprised of a bobbin, winding, shield, potting material, magnetic core or core, and the like. The bobbin generally refers to a support around which a coil is wound. Most of fixed inductors or adjustable inductors (such as oscillating coils, choke coils and the like) with larger volumes surround enameled wires (or yarn-covered wires) on a framework, and then magnetic cores or copper cores, iron cores and the like are arranged in an inner cavity of the framework so as to improve the inductance of the inductors. The framework is usually made of plastics, bakelite and ceramics, and can be made into different shapes according to actual requirements.
