Fixed inductors are extremely common components that are used in a variety of electronic circuits, from radio transmitters to timers and logic circuits. The ELJ-RE2N2DF2 is an example of a fixed inductor that is used in many applications. This article will discuss the application field of the ELJ-RE2N2DF2 and its working principle.

Application Field

The ELJ-RE2N2DF2 is a SMD (surface mount device) type inductor, which means that it is a small inductor designed to be used directly on a printed circuit board (PCB). It is also a surface mounted technology (SMT) component, meaning that it can be soldered directly onto the board without having to go through through-hole technology. This type of inductor is often used in radio applications, such as radio frequency amplifiers, antennas, and receivers.

The ELJ-RE2N2DF2 is also used in many logic circuits, such as in power supplies, voltage regulators, timers, and noise filters. It is a low-cost, reliable, and compact option, which makes it ideal for use in these applications. Furthermore, the ELJ-RE2N2DF2 is capable of operating at high frequencies, which makes it suitable for use in high-speed circuits.

Working Principle

An inductor is an electrical component that works on the principle of inductance. Basically, it is a coil of wire that creates an inductance when current is passed through it. Inductance is created by changing the magnetic field of a coil of wire, which produces a voltage (known as inductive reactance) that opposes the current passing through it. This property is known as self-inductance, or just inductance.

The ELJ-RE2N2DF2 is a surface-mount component, meaning that it is designed to be used directly on the PCB. This means that the inductor is physically and electrically connected to the circuit board. The ELJ-RE2N2DF2 uses a ferrite core, which is a type of material that is used to create a magnetic field when current is passed through it. This type of core provides high levels of inductance, making it ideal for applications that require high levels of inductance.

The ELJ-RE2N2DF2 has an inductance range of 0.01 μH to 100 μH, which is capable of covering most applications. It also has a maximum current rating of 1.25A and a low resistance (DCR) of 0.32Ω. Its maximum operating temperature is 125°C, which makes it ideal for high temperature applications.

Conclusion

The ELJ-RE2N2DF2 is a low-cost and reliable inductor that can be used in many different applications. Its compact size and high levels of inductance make it ideal for radio frequency amplifiers, power supplies, voltage regulators, timers, and noise filters. The ELJ-RE2N2DF2 works on the principle of inductance, using a ferrite core to create a strong magnetic field when current is passed through it. This inductor is a great choice for designers looking for a cost effective and reliable inductor for their circuits.
