0819-30K

Fixed inductors are one of the most common passive components used in the electrical industry. They vary in shape and size, but they all share a similar feature: an induction coil that has a predetermined inductance value. This is the most important characteristic of a fixed-inductance component. The value of this inductance is determined by the material that it is made of, its physical dimensions, and the number of turns in the coil itself. Depending on the application, these components can have a single winding or multiple windings, each with different characteristics.

The 0819-30K (or SMD) series of fixed inductors is a line of monolithic inductors that is commonly used in radio- and high-frequency applications. The inductor is composed of toroids or wire-wound coils, depending on the type of application. Its core is made of a ferrite material, while its windings are made of an insulated metal wire. In addition, the inductor can exhibit a number of characteristics, such as inductance, self-resonance frequency, current derating, and temperature coefficient.

The working principle of the 0819-30K series of fixed inductors is based on the fact that when a current is passed through its winding, an electromagnetic field is generated, which creates a related magnetic field. This magnetic field is then used to create an electrical field, which then consequently generates an inductance. The strength of this inductance is determined by the core material, number of turns, and other properties of the inductor.

These components are typically used for signal filtering and blocking, chokes, isolation impedances, and other similar applications. They can also be used to improve attenuation in noise correction circuits, as well as for transmitter and receiver applications. Furthermore, some of their properties, like the self-resonance frequency, make them ideal for RF matching circuits too.

In conclusion, the 0819-30K series of fixed inductors are inductors specifically designed for radio- and high-frequency applications. Their inductance is determined by the material the core is made of, the number of turns in its windings, and the other inductor characteristics. They are used for various filtering and blocking applications, amongst others.
