Fixed inductors, also known as choke coils, are an important type of electronic device used to store energy in electric and magnetic fields. The 17473C is a popular fixed inductor intended for the RF and switching power supply industry. This article will discuss the application field and working principle of the 17473C.

The 17473C is an ideal fixed inductor for use in RF and switching power supplies due to its small size and high self-resonant frequency. It is composed of a ferrite core wound with copper wire, with a special wire used to electrostatically shield the core. This provides excellent inductance characteristics over a broad frequency range, making it suitable for frequencies from 10 kHz up to 3GHz. Additionally, it has superior performance in large currents, low interface magnetic flux, and low power dissipation.

The 17473C is commonly used for a wide range of RF and switching power supply applications. It is suitable for use in switching regulator circuits, power converters, and other high-performance digital applications. It is also used in switching converters, motor and drive circuits, and LNA, PA, and antenna circuits. Many manufacturers use the 17473C for their cellular phones and other portable electronics.

The 17473C performs several important functions in any circuit that uses it. Primarily, it stores energy in an electrostatic field and releases this energy in response to a trigger or signal. This allows for efficient power transfer from one point to another without any loss of energy. Additionally, it helps protect the components of any circuit from electromagnetic interference, as well as controlling the amount and speed of electrostatic currents in RF circuits.

The working principle of the 17473C fixed inductor is fairly straightforward. It is composed of a copper coil wrapped around a ferrite core. When electricity is applied to the coil, it creates a magnetic field, which induces a current in the coil. This induced current then flows through the center of the core, creating an electrostatic field, which stores energy. When a signal is applied, the stored energy is released and current flows through the coil again, restoring the magnetic field.

The 17473C fixed inductor is an invaluable tool in any RF or switching power supply application. Its small size and high self-resonant frequency make it an ideal choice for high-performance digital applications, while its superior performance in large currents, low interface magnetic flux, and low power dissipation make it suitable for a variety of RF and switching uses. Its working principle is fairly straightforward and allows for efficient power transfer without any loss of energy.
