Fixed Inductors

 

Introduction

The IMS05ER471K is a fixed inductor specifically designed for use in various high frequency circuit applications. As with other types of inductor components, this device stores electrical energy in the form of a magnetic field and acts as a reactive device in AC circuits. It is mainly used in switch mode power supplies, RF circuits, telecom and optical applications, and audio applications as a filter component.

Application Field

The IMS05ER471K is a multi-layer shielded inductor designed for use in DC to DC convertors, multiple output SMPSs, LED drivers, telecom and optical applications, and all other high frequency circuits. It can be used in various types of circuits, such as buck, boost, buck-boost, charge pump, polarity inversion, and current resonant. These inductor components are also used in RF circuits, such as impedance matching networks, antenna matching networks, low noise amplifiers and filters circuits. The inductor can be used in many audio applications, such as subwoofers, midrange and tweeter speakers, crossover networks, and headphone amplifiers. It can also be used in various automotive applications as filters in audio power amplifiers.

Working Principle

The IMS05ER471K is based on Faraday’s Law of induction, which states that the voltage induced in a conductor is proportional to the rate of change of magnetic flux through it. This inductor component consists of two magnetic cores, wound with a single insulated wire, separated by a thin dielectric material (usually air or plastic). When current is applied to the wire it creates a magnetic field, which is then used to induce a voltage in the other core. The amount of voltage induced is determined by the inductor’s core material, number of turns of wire, and size (distance between the two cores). The inductor is typically used in high frequency circuits as part of a filter. As AC signals pass through the inductor, the current is restricted by the inductor’s large impedance at the resonating frequency. This reduces the signal intensity and has the effect of blocking out certain frequencies that are not desired. The inductor is often used in combination with a capacitor to form a low-pass filter, which allows only signals at lower frequencies to pass through.The device is also capable of storing energy within its magnetic field. As current rises and falls, the magnetic field charges and discharges, accumulating and releasing energy respectively. This can be useful in certain SMPS circuits, as it allows for the energy stored in the inductor’s field to power the circuit during times when the input current is too low.In conclusion, the IMS05ER471K is a fixed inductor designed for use in various high frequency applications, such as switch mode power supplies and RF circuits. It works based on the principle of induction, where the current passing through the inductor’s wire creates a magnetic field that can be used to induce voltage in the other core. Additionally, the device can be used to store energy in its magnetic field, and can also be used together with other components to form filters.
