Fixed Inductors

LD1-2R2-R is a fixed inductor, which is an electronic component that resists changes in electric current. It consists of a coil of wire encompassing a magnetic core. The most widely used fixed inductor is a rod core inductor, often referred to as a choke. They are used in a wide range of applications to block or filter electric current, including power supplies, audio systems, and consumer electronics.

Application Field

LD1-2R2-R fixed inductors are extensively used in the aerospace and defense industry since they are able to withstand high levels of vibration, humidity, and dust. They are also used in industrial and consumer electronics for AC/DC power conversion, filtering, and ripple reduction.

In audio applications, LD1-2R2-R fixed inductors are used for power supply filter inductors, output inductors, signal coupling, and power amplifier input switching. Some other common applications are DC-DC converter and switching mode power supply, electromechanical switches, high frequency signal processing, electronic equipment, medical instrumentation, radiotelephone and radar system, motor drives, cell phones and portable audio systems.

Working Principle

Fixed inductors work on the principle of inductance. Inductance is an effective property of the conductors and cores that limits the rate at which electricity can be passed through them. When an alternating current passes through an inductive component, the electrical energy of the current is stored in the magnetic field produced by the component. This magnetic field opposing the flow of electricity induces a voltage at the terminals of the inductor.

Fixed inductors work by limiting the amount of voltage fluctuation through electric current. The inductor increases in voltage with an increase in current and this opposition to current flow is known as inductive reactance. It is basically the resistance that a circuit experiences due to a change in current. The inductance of an inductor is usually measured in henries (H).

The primary reason that fixed inductors are commonly used is because they are able to provide a low-cost solution for stabilizing and maintaining electrical current in a circuit. They can be easily adjusted in order to optimize the current that is needed for a particular application. They are also effective at filtering out electrical noise that can interfere with signals and reduce the signal quality. Fixed inductors are frequently used in audio systems, telecommunications, and computer networks.
