Fixed Inductors

A fixed inductor is a passive two-terminal electrical component that stores energy in a magnetic field. Its symbol on a circuit schematic usually consists of two lines, and the graphical symbol of an inductor is the coil of wire. They come in two types: air core and ferrite core. Air core inductors have the advantage of a lower DC resistance, whereas ferrite core inductors have a much higher inductance in a smaller size. Fixed inductors are widely used in power management, telecommunications, and other electronics.

18R254C Application Field and Working Principle

The 18R254C is a fixed air core inductor from STAG group. It is designed for use in small, cost efficient power supplies, such as in a laptop or notebook computers, and other consumer electronic devices. The inductor offers excellent efficiency for energy storage at the highest possible inductance values for the given size. Its low overall resistance allows for very low losses in switching power supplies.

The working principle of a fixed inductor is that it uses magenetic flux to store energy. The inductor works by forming a magnetic field, which is used to store energy in the form of a magnetic field or flux. When a flow of current passes through the inductor, the magnetic field generated by the current induces a voltage across the inductor. This voltage opposes the current, which is known as inductive reactance. The name inductance refers to this ability of the inductor to "induce" a voltage with a changing current.

The 18R254C is an example of this type of inductor. The inductance value of this component is 18µH and it has a resistance value of 0.45 Ω. The maximum working voltage is 35V. It is a very small inductor which measures only 5.5mm in diameter and is rated to handle up to 1.00A of current. Because of its small size, it is ideal for use in space-restricted applications. Additionally, it does not require any external components in order to function properly.

In conclusion, the 18R254C is a fixed air core inductor manufactured by STAG group. It offers excellent efficiency for energy storage at the highest possible inductance values for the given size, and its low overall resistance allows for very low losses in switching power supplies. Additionally, its small size makes it ideal for space-restricted applications. Fixed inductors like the 18R254C are widely used in power management, telecommunications, and other electronics.
