Fixed Inductors

Fixed inductors, also known as chokes, coils, or inductors, are electronic components that use coils of wire to store energy in a magnetic field. The 4922R-17H is a type of fixed inductor that is used in electronic circuits. Its wide range of applications in different circuits include high frequency filtering, DC blocking, signal processing, and power conversion.

Application Field

The 4922R-17H is a high-current inductor, which makes it suitable for DC-to-DC switching converters, DC-to-AC inverters, and other power conversion applications. It also has a wide variety of uses in high-frequency switching regulators, TV tuners, and demultiplexers. It can also be used in electronic circuits for filtering, signal processing, and DC-blocking applications.

Working Principle

An inductor is an electronic component that works by storing energy in a magnetic field. When a current is induced in a coil of wire, a magnetic field is created around the wire, and the magnetic field stores energy. This stored energy is released when the current flow is interrupted.When current is applied to the 4922R-17H inductor, the current flowing through the winding causes a magnetic field to be created around the winding. This magnetic field stores energy. When the current is interrupted, the magnetic field collapses, and the stored energy is released. This is known as inductive action.

Advantages

The 4922R-17H inductor is well-suited for high-frequency and high-current applications due to its strong inductance. It is also cost-effective and has wide availability. Additionally, its low profile and robust construction make it reliable when used in circuits.

Disadvantages

Inductors are not ideal for all applications as they can be damaged when exposed to high currents. Additionally, they can be prone to overheating under certain conditions, which can cause permanent magnetizing and signal disturbances.

Conclusion

The 4922R-17H is a type of fixed inductor that is capable of storing energy in a magnetic field under certain conditions. It is well-suited for a variety of applications, including high-frequency filtering, DC blocking, signal processing, and power conversion. Its wide availability and low cost make it an attractive choice for many electronic circuits. However, it does have some limitations, such as high-currents, overheating, and signal disturbances.
