Introduction to Fixed Inductors

A fixed inductor, also called a choke, is a passive electronic component used in many applications. It is made up of one or more turns of insulated wire and is used to store energy in the form of a magnetic field, and release it in the form of an electrical current. Inductors can be used to block high frequency noise signals and are also used in circuits to filter out certain frequencies or as AC-to-DC current converters. Inductors are commonly used in a wide variety of electronic products, including automotive electronics, avionics, computer systems, medical electronics, and consumer electronics. They are also essential components in power distribution supplies, audio amplifiers, and most AC circuits.

ELJ-RE18NGF2 Fixed Inductor

The ELJ-RE18NGF2 fixed inductor is a high-power, high-reliability component from Murata. It is designed for use in DC-DC converter circuit applications. It is based on the company\'s MCQN series, which is a custom-made surface mountable inductor that provides high performance and reliability. The ELJ-RE18NGF2 features a ferrite core and a spiral wound coil with an electrical property of 1.8nH. It is a surface-mount type package with the terminals on the bottom of the device.

Working Principle

Fixed inductors rely on the principle of a Faraday’s law of induction, which states that when a conductor is exposed to a changing magnetic field, an electric current is induced in the conductor. In fixed inductors, a magnetic field is created by passing an electrical current through a coil of wire. The magnetic field then induces an equal and opposite current in the coil, resulting in a magnetic field around the inductor. When an alternating current (AC) is applied to the inductor\'s terminals, the magnetic field around the core changes at the same frequency as the current. This changing magnetic field induces a voltage in the coil, which is stored in the form of energy. When the AC source is removed, the stored energy is released in the form of a current. This magnetic field can also be used in a variety of other applications, such as inductive loads, generators, filters, and amplifiers.

Applications

The ELJ-RE18NGF2 fixed inductor is commonly used in DC-DC converter circuit applications. It is also used in switching power supplies, portable computer power supplies, and AC/DC adapters. The device is also used in solar cell charging circuits, battery management systems, and switching regulators. This inductor is also suitable for use in other electronics products such as automotive electronics, consumer electronics, and communication equipment.The ELJ-RE18NFG2 is well-suited for applications requiring high performance and reliability, such as those in which the operating environment is very harsh, such as in automotive applications. The device\'s high power levels and high efficiency make it the ideal choice for such applications.

Conclusion

The ELJ-RE18NGF2 fixed inductor is a high-power, high-reliability component from Murata. It relies on the principle of Faraday\'s law of induction to create a magnetic field, which is then used to store energy.
