What Is an Inductor Choke?
An inductor choke is a passive component used to achieve stable current supply in power lines and suppress high-frequency noise.
Generally constructed with coil-shaped conductors and a magnetic core, it impedes high-frequency currents and allows low-frequency currents to pass through, based on a property called inductance. Inductor chokes operate based on the properties of inductance and the magnetic core. The current flowing through the coil generates a magnetic field, which attempts to sustain the current. Additionally, the magnetic core concentrates the magnetic field, effectively suppressing high-frequency noise.
Inductor chokes find applications in various fields such as power circuits, electronic devices, communication equipment, and medical devices. Its main components include the coil and the magnetic core. The coil serves as the conductor for current flow, while the magnetic core is used to concentrate the magnetic field.
