Fixed inductors are inductors that have a fixed inductance value. They are typically used in a wide range of electronics, such as radio cables, computer circuits, power supplies, mobile communication systems, and digital signal processing. The B82477G4392M000 is a fixed inductor that is designed for the automotive industry.

The B82477G4392M000 is a low-profile radial lead inductor with a rated inductance of 392µH and a saturation current up to 6.5A. The core material is composed of a ferrite beads, and its construction is based on the principle of a coupled inductor, enabling high ripple current ratings and low distortion. The inductor also has a low DC resistance for higher efficiency, and it is rated to operate over a temperature range of -55°C to +125°C.

The B82477G4392M000 is applicable in automotive applications, such as engine control systems, immobilizers, and electromobility systems. It can also be used in power supplies for compact electronic devices, as well as portable battery-powered electronics. The inductor can also be used in switch mode power supplies, DC-DC converters, and other high-frequency applications.

The working principle of the B82477G4392M000 follows the principles of electromagnetic induction. When a voltage is applied to its coil windings, an electric current is generated which, in turn, produces a magnetic field. The field induces eddy currents in the core material, creating a back-EMF voltage which opposes the applied current and limits further current flow. The inductance value is directly proportional to the number of turns in the winding and inversely proportional to the core diameter.

The B82477G4392M000 is capable of providing high stability and reliability in a wide range of applications. It features a rugged construction, and its ferrite core allows for high saturation current ratings. The component also has a low DC resistance for high efficiency, and its temperature range is suitable for tough automotive applications. This inductor is an ideal choice for automotive electrical and electronics systems.
