Fixed Inductors

An inductor, also known as a coil or reactor, is a basic two-terminal passive electrical component that stores electrical energy in its magnetic field. It works on the principle of Faraday\'s law of induction, which states that when a conductor carrying a current is surrounded by a changing magnetic field, an electromotive force will be induced in the conductor. Fixed inductors are a type of inductor that have a fixed inductance, which cannot be adjusted.

LQG18HH27NJ00D

LQG18HH27NJ00D fixed inductor is a passive component capable of providing consistent inductance value with high reliability and excellent high frequency performance. This component is manufactured using highly advanced thin film printed coils process technology. The ceramic ferrite core and surface mount design of this product provide miniaturization, high power density and low profile construction. It is suitable for automotive, consumer and industrial applications.

Application Field of LQG18HH27NJ00D

The LQG18HH27NJ00D inductor is suitable for use in a wide range of automotive, consumer and industrial applications. It can be used in high frequency power converters, DC-DC converters, switching power supplies, inverters, DC-AC converters, motor drives, ballast circuits, and high frequency transformers. It can also be used in portable electronic devices including remote communications, handheld radios, telephones, navigation, and laptop computers.

Working Principle of LQG18HH27NJ00D

The working principle of the LQG18HH27NJ00D is based on Faraday’s Law of induction. Whenever a changing current passes through a conductor, a magnetic flux is developed around the conductor according to this law. The varying magnetic field induces an electromotive force (EMF) in the conductor, which then opposes the change in current that created the flux, thus limiting the current. This phenomenon is known as self-inductance.

In addition, the LQG18HH27NJ00D inductor also employs the principle of mutual inductance. This occurs whenever two wires are wound around each other, the varying current in one induces a current in the other, even if the two are isolated from each other. This allows the LQG18HH27NJ00D inductor to act as a transformer, allowing electrical signals to be transferred from one circuit to another without direct contact.

The LQG18HH27NJ00D inductor can also be used to filter or block low-frequency signals while allowing high-frequency signals to pass through. This is done by mounting the inductor in series with the signal source, as the inductor will limit the flow of low-frequency signals while allowing high-frequency signals to pass through with minimal attenuation.
