Fixed Inductors

Fixed inductors, otherwise known as "coils" or "chokes," are passive components used in electrical circuits for the purpose of storing energy in the form of a magnetic field. They are also used extensively to create tuned circuits which allow the user to adjust the frequency response of a certain portion of the circuit. The LQW15AN3N4B80D is a fixed inductor which has a wide range of applications and a specific working principle.

Applications of LQW15AN3N4B80D Fixed Inductors

The LQW15AN3N4B80D fixed inductor is one of the most versatile inductors available, allowing for the implementation into both sophisticated and complex designs. Some of its most common applications include:

Working Principle of LQW15AN3N4B80D Fixed Inductors

Fixed inductors or “chokes” are passive components that store energy in a magnetic field whenever a current passes through them. This phenomenon is known as self-inductance. Whenever the current is changed, a back-emf is created in the opposite direction of the applied voltage. As the current is flowing through the inductor, a magnetic field is created in a direction that opposes the increase in current. This is known as Lenz’s law, named after the 19th-century German physicist Heinrich Lenz.

The value of the stored energy in the magnetic field is proportional to the inductance value, measured in units of Henrys (H). One Henry is the amount of inductance required to induce a potential difference of one volt when the current flowing through the inductor changes at the rate of one ampere per second.

The ideal equation of the magnetic field of an inductor is given by the formula: H = N ∗ I, where H is the magnetic field strength (in Amperes/meter), N is the number of turns in the inductor, and I is the current flowing through the inductor (in Amperes).

In practical applications, different types of inductors are used depending on the desired frequency of the circuit. For example, low-value inductors with low inductance can be used for low-frequency signals such as audio, while high-value inductors with high inductance are used for high-frequency signals such as RF. The LQW15AN3N4B80D is a high-value inductor used for high-frequency signals.
