Fixed inductors are an important component in electrical circuits, designed to store electromagnetic energy and deliver it to create a particular current or voltage. The 4922-391L is a type of fixed inductor specifically designed to provide increased power efficiency and stability across a range of applications.

The 4922-391L is a surface mount, shielded power inductor designed for medium to high current, small-signal switch mode, power supply applications. Its operating temperature range of -40 to +105°C makes it suitable for a wide variety of environments and settings, providing reliable performance across a range of challenging commercial and industrial conditions.

The inductor is constructed with high temperature composite coil technology for improved performance and reliable power delivery. Its inductance value of 1.5 µH makes it suitable for input and output filtering and loop stabilization in switch mode power supplies. In addition, its tight tolerance of 20% means it is also suitable for secondary-side conversion applications.

The 4922-391L has several features that make it suitable for a wide range of applications. Its compact and lightweight profile makes it the ideal solution for space-saving and low-profile designs. It also requires minimal board space, making it an ideal choice for designs that require a high level of integration. It has excellent thermal characteristics, allowing for efficient heat dissipation and reliable performance in high temperature applications. Its high current capacity and minimal DCR allows it to deliver maximum power in a wide range of conditions.

The working principle of the 4922-391L is based around its ability to store electromagnetic energy. It consists of a coil of wire wrapped around a ferromagnetic core. When an electric current is passed through the coil, a magnetic field is produced within the core, which stores the electromagnetic energy. This stored energy is then released when the electric current is reduced or reversed, causing the magnetic field to collapse and producing a voltage or current.

The 4922-391L is a powerful and reliable component that is suitable for a wide variety of applications, including input and output filtering, loop stabilization, and secondary-side conversion in switch mode power supplies. Its numerous features, such as its compact and lightweight profile, excellent thermal characteristics, and tight tolerance, make it an ideal choice for designers who require efficient and reliable performance across a wide range of applications.
