Fixed Inductors: ER1840-13JR Application Field and Working Principle

Fixed Inductors are electronic components that are widely used in communication, medical, automotive, and other industries due to their ability to efficiently store energy. The ER1840-13JR is a specific example of a fixed inductor designed to be especially helpful in low voltage input and output circuits. It has a current rating of 220mA and an inductance range of up to 130 mH. It also has a ferrite core, making it an ideal choice for applications with low power consumption requirements and for stability in high frequency operations.

Application Field

The ER1840-13JR fixed inductor is a low profile, leaded medium frequency component, specifically designed for cost and performance sensitive applications. Typical applications include low voltage power converters, AC/DC and DC/DC converters, forward converters, switch mode power supplies, voltage regulators, inverters, antenna tuning, and more. The compact size of the inductor enables them to be ideal for applications with a limited number of components.

The ER1840-13JR is suitable for a wide range of uses, particularly in noise-critical applications such as automotive and consumer electronics where high power and fast switching operations are required. The inductor also features high-frequency performance and low D.C. losses. Furthermore, due to its wide current range it is ideal for high current applications requiring immunity to noise.

Working Principle

The ER1840-13JR fixed inductor works on two main principles, magnetic induction and the law of Faraday. By passing a current through the coil, a magnetic field is created in the core material, which in turn stores energy. This is the basis of inductance. When the current flow is reversed, the inductor’s magnetic field collapses all at once, creating a backwards voltage against the changed flow. This is a phenomenon known as the Back-EMF or Counter-Electromotive Force, and is used to create oscillating signals in inductors or to regulate the current in circuits.

Another concept of how an inductor works is based on Lenz\'s law. This states that an electric current will create a magnetic field opposing the change that caused it. Therefore, when an inductor is exposed to an otherwise sudden change in current, the magnetic field will oppose that change and slow it down, creating an inherent resistance to change. In this way, inductors act to reduce and slow down changes in current in order to maintain a steady flow of power.

The ER1840-13JR is a reliable and efficient fixed inductor and can help make a wide variety of electronics projects from low current converters to high current switching solutions a reality. With its unique features and benefits, it is an optimum choice for various applications.
