[0002] An inductor is an electronic component that stores electrical energy. It affects the current through the change of the magnetic field. The inductor is formed by winding a coil. When an electric current passes through, a magnetic field is generated and energy is stored. When the current changes, the magnetic field also changes, thereby generating a reaction force (self-induction) on the current. Inductors are widely used in electronic circuits to help control current and voltage and stabilize the circuit performance.

[0003] An integrally formed inductor is an integrated inductor, which is smaller in volume than the traditional discrete inductor, helping to save space on a compact circuit board. It is usually used to improve the performance of electronic devices, reduce space occupation, and simplify the circuit design. The integrally formed inductor provides a solution with a compact size and stable performance, and is widely used in the design of modern electronic products. Selecting a suitable integrally formed inductor can effectively improve the performance and reliability of the circuit.
