Fixed Inductors

A fixed inductor is an electronic device, also known as a choke, which is used to filter electrical signals. This type of inductor has many different components, including the core, windings and an external housing. The core is a material with high magnetic permeability, such as iron, which is used to create a magnetic field. The windings are composed of wire that is wound around the core and provides the current flow. The external housing is usually made from plastic or metal and provides protection from environmental elements.

The 0819R-08J application field and working principle is a specific type of fixed inductor. It is used to filter out the noise and power ripple from a power supply. This particular type is designed with a ferrite core and an epoxy encapsulation to shield against moisture and dust. The device consists of two coils that are connected electrically in series and mounted concentrically on the ferrite core. The coils are wound to create a double turn. This arrangement creates a high inductance and helps reduce power ripple in the process.

The primary usage of the 0819R-08J is to filter out power ripple in applications such as automotive electronics, home appliance controllers, alternating current (AC) motors and power converters. Its working principle is that an electric current is induced in one coil, as a result of the changing magnetic field created by the core, and this produces a voltage in the other coil. This process filters out unwanted frequencies and helps deliver a smoother power supply to the application.

In summary, the 0819R-08J application field and working principle is a specific type of fixed inductor. It is typically used to filter out power ripple and help deliver a smoother power supply to the application. This is accomplished by its two coils that are mounted on the ferrite core, which creates an induced voltage in one coil when a current passes through the other coil.
