Fixed Inductors

An inductor, also referred to as a coil, choke or reactor, is a passive electrical component used in electronics. It is basically a two-terminal device consisting of a coil of wire, usually wound around a frame of iron, copper or other magnetic material. Fixed inductors are a type of inductor that has a fixed value and doesn’t change over time. The fixed inductor type is commonly used in circuits such as radio frequency (RF) and power amplifiers, transformers,and filters.

The LQH43CN1R5M03L is one such type of fixed inductor. This device is a molded and shielded wire wound inductor with a 5. 0μH inductance, a maximum frequency of 3MHz, and a rated current of 0.50A. In terms of applications, it is generally used in power supplies, DC/DC converters, AC/DC converters, and other power electronics.

The working principle of a fixed inductor is based on the relationship between an electric field and a magnetic field. The electric field is formed by an electric current flowing through the inductor and the magnetic field is created when a voltage is applied across the inductor. Then, as the electric field interacts with the magnetic field, an electromagnetic force is created. This electromagnetic force is responsible for creating the inductance. The inductance of a fixed inductor is constant and does not depend on the frequency of the alternating current. This is why it is typically used in power electronics circuits where the frequency is steady.

In conclusion, the LQH43CN1R5M03L is a type of fixed inductor with a 5.0μH inductance, a maximum frequency of 3MHz, and a rated current of 0.50A. It is mainly used in power supplies, DC/DC converters, AC/DC converters, and other power electronics. The working principle of a fixed inductor is based on the relationship between electric and magnetic fields, resulting in an electromagnetic force that creates the inductance. Furthermore, its inductance is constant and does not depend on the frequency of the alternating current.
