Inductors, Coils, Chokes
![](/image/categories/inductors-coils-chokes.jpg)
Inductors, Coils, Chokes are common components in electronic circuits that mainly play a role in energy storage, filtering, oscillation, delay, and notch effects in the circuit. An inductor is made of a coil, and when current passes through it, a magnetic field is generated around it to store energy. A coil is a type of inductor, usually referring to a component composed of multiple coils with a large inductance. Choke coil is a specially designed inductor mainly used to prevent or limit changes in current, commonly used for power filtering and signal isolation. The design principles of these components are based on the law of electromagnetic induction, with characteristics such as impedance current variation and the generation of electromotive force through self induction, making them indispensable components in electronic circuits.
