Fixed Inductors: LK21252R7M-T Application Field and Working PrincipleInductors, also called coils or reactor, are one of the basic components of the electrical system. They are widely used in communication technology, electrical machines, precision engineering, aerospace and other applications. The LK21252R7M-T is a fixed inductor that performs a vital role in a number of applications. Application FieldAs a fixed inductor, the LK21252R7M-T is mainly used for filtering the >frequency and power in the electrical system, which can largely reduce the harmonic distortion and electronic noise. It is suitable for rectifier circuits, switching power supply, automotive and sound systems. In addition, it can be used in power deficiency process as a booster coil, choke coil, and transformers. Working PrincipleAn inductor is a passive two-terminal electrical device with an air or magnetic core, which makes it possible for generate a magnetic field when electricity flows through it. Fixed inductors are constructed by winding the wire around the core. When current passes through the inductor, a magnetic field will be generated around the electrically conductive coil. The magnetic field will resist any changes in current flowing through it, and the flux of the coil will induce an electromotive force (EMF). This electromotive force will eventually cause its own voltage and circulating current in the circuit.Besides, the frequency of the alternating current will also affect the behavior of the inductor. The alternating current passing through the coil will induce a corresponding alternating voltage, and the larger the frequency is, the higher the impedance of the inductor is. ConclusionThe LK21252R7M-T fixed inductor has a wide range of applications, from filtering frequencies and power to using for boosting and transforming. It is suitable for rectifier circuits, switching power supply, automotive, and sound systems. It works by forming a magnetic field that resists any changes in current flowing through it and inducing an electromotive force that creates its own voltage and current.
