RL875S-271K

Fixed Inductors

Fixed inductors, also known as coils, chokes, or reactors, are passive components that store energy in a magnetic field when electric current flows through them. They are used to filter current and block direct current (DC) in various electronic circuits. A fixed inductor is often represented by the letter L in the schematic diagrams. An example of a fixed inductor is the RL875S-271K, which is a surface mount inductor.

RL875S-271K Application Fields

The RL875S-271K fixed inductor is used in circuit boards that require high-current infrastructure. In particular, it can be used to aid high-efficiency power supplies, audio amplifiers, and frequency converters. Its high current and very low voltage ratings make it suitable for a variety of power management applications. Because of its small size, it is ideal for computer electronics and other portable devices.

RL875S-271K Working Principle

Fixed inductors, including the RL875S-271K, use an alternating magnetic field created by a coil, or a series of coils, along an iron core to store electrical energy. When electric current passes through the device, the electric field creates a magnetic field, which is stored in the inductor. When the current ceases to flow, the stored magnetic field collapses, creating a current in the opposite direction. This phenomenon enables an inductor to filter current or block DC in various circuits.

The RL875S-271K fixed inductors\' inductance is determined by the number of turns of the coil and the permeability of the core material. The RL875S-271K features an internal copper core and is constructed using multiple small coils to achieve higher levels of inductance. Its internal design ensures that it can withstand higher levels of current than standard surface mount inductors.

The RL875S-271K is used in a wide range of power management applications, such as for DC-to-DC converters, power supplies, and audio amplifiers. Thanks to its robust construction and high current ratings, it is suitable for a variety of applications requiring high-current infrastructure.
