Fixed Inductors

An electrical current induces a magnetic field. The strength of this field is proportional to the amount of electric current that is flowing. Electromagnetic induction is the process of using a coil of wire to store this energy in a magnetic field for later use, but it has limitations. A fixed inductor, such as the DRA124-150-R, a popular chip inductor, uses components to convert electrical energy into a magnetic field and then store that energy for later use.

Application Field

The DRA124-150-R is used in electronic systems to convert electrical energy into magnetic energy and then store that energy. The chip inductor can be used in applications from power distribution to pulse transformers, and from filter inductors to dc-dc converters. It is particularly useful in machines where it is necessary to transform energy, such as barcode scanners, power supplies, and many other kinds of electronic appliances.

Working Principle

The working principle of the DRA124-150-R is based on Faraday\'s law of induction. This law states that when a magnetic field passes through a conductor, an electromotive force is generated. The chip inductor uses this force to generate a magnetic field and then store the energy in a magnetic core. The chip inductor consists of three components: a conductor, a coil, and a core. The conductor is a single wire that carries an electric current, and the coil is a special type of a conductor that is wound around a material, such as an iron core. The iron core helps to increase the strength of the magnetic field generated by the coil.The electric current that flows through the conductor generates a magnetic field that is directed towards the coil and the core. This magnetic field induces a voltage in the coil, which then generates a magnetic field in the core. This magnetic field stored in the core is referred to as the inductance, and the amount of inductance is proportional to the amount of electric current flowing through the conductor. The inductance is then used to store energy for later use.

Conclusion

The DRA124-150-R chip inductor is a useful component for storing electrical energy in a magnetic field. It is used in a variety of electronic systems, from barcode scanners to power supplies, and its working principle is based on Faraday\'s law of induction. The three components of the inductor, the conductor, the coil, and the core, help to generate a magnetic field that can be used to store the energy for later use.
