< p > < strong > Fixed Inductors < / strong > < / p >Fixed Inductors are widely used in power electronic systems like Electric Machines, Power Drives, Industrial Automation and Automotive Electronics. The LAL04KB471K is a fixed inductor that is commonly used in many of these applications. In this article, we will explore the application field and working principle of this particular inductor. < p > < strong > Application Field < / strong > < / p >The LAL04KB471K is a surface mount component which is suitable for a wide range of applications. It is a non-polarized fixed inductor with an inductance of 470uH. The maximum operating temperature is up to 125°C and the rated current at 25°C is 1.2A. This type of inductor is mainly used in power supplies, switch mode converters, inverters, controllers, and DC-DC converters. The LAL04KB471K is ideal for high frequency power electronic applications because it has low DC resistance and low inductance value. This inductor has an electromagnetic interference (EMI) shield which helps to reduce EMI noise. It is also a better choice when it comes to high working frequency applications as it provides low-loss characteristics.< p > < strong > Working Principle < / strong > < / p >An inductor is an electrical component that induces electric current when the voltage changes. A fixed inductor, such as the LAL04KB471K, has a fixed inductance and is usually used as a component of an inductive circuit. Inductors work according to Faraday’s law of induction. When an electric current changes, it produces a magnetic field around it. If the current is constant, a small change in voltage will cause a variation in the strength of the magnetic field and the current produced. This change in magnetic field strength is known as Inductance. The LAL04KB471K is a non-zero-distance inductor which means that it has a fixed magnetic field strength and a fixed inductance. The inductor works by producing a stable magnetic field which is used to induce voltage and electric current in the circuit. In summary, the LAL04KB471K is a surface mount fixed inductor with 470uH inductance and 1.2A rated current at 25°C. It is suitable for high frequency applications and has an EMI shield which helps reduce EMI noise. The inductor works according to Faraday’s law of induction and produces a stable magnetic field which is used to induce electric current in the circuit.
