ELJ-RE2N7ZFA Inductors, Coils, Chokes

Fixed inductors are electrical components characterized by their ability to maintain a constant inductance, hence the name. The ELJ-RE2N7ZFA is one of the many such components in the market. This article examines its application field and working principle.

Application Field

The ELJ-RE2N7ZFA has wide application in the electronics industry. This multi-purpose inductor is commonly employed in various radio frequency and communication applications. It is especially suitable for high frequency signal processing, such as transmission and reception. Additionally, it is commonly used in switching power supplies, power management systems, and other power conditioning circuit applications.

Working Principle

The working principle of the ELJ-RE2N7ZFA is based on the basic laws of physics. An inductor is a passive electrical component responsible for generating an electromotive force when a varying current passes through it. This is known as induction. The inductance of an inductor is the ratio of the electromotive force to the rate of change of current. In other words, the inductance is proportional to the amount of current passing through the inductor. The ELJ-RE2N7ZFA is a type of fixed inductor, designed to maintain a constant inductance value, regardless of the amount of current passing through it.

The inductor is generally composed of two main components: the core and the coil. The core is made of ferromagnetic material, which usually consists of several layers of metal or ferrite sheets. The coil is composed of several turns of wire wound around the core. When the current passes through the coils, it generates a magnetic field, which induces a voltage in the coil. This voltage is then dissipated as power. As the current continues to vary, the inductance value remains unchanged, due to the constant field generated by the core.

In conclusion, the ELJ-RE2N7ZFA is a type of fixed inductor with various applications in the electronics industry. It works based on the principle of induction, whereby a constant field is created by the ferromagnetic core and the varying current generates an electromotive force. This force is then dissipated as power, and the induced voltage is proportional to the rate of change of current. This information will help engineers understand how they can integrate this component into their designs.
