Fixed inductors, also known as chokes, comprise an essential integral part of electronic devices and equipment. The most common type is the HA55L-3623220LF, which is widely used in various electronics systems due to the wide range of its application fields and its working principle.

The HA55L-3623220LF is a generally low-priced, cylindrical inductor that has a diameter of 5.5mm and a height of 2.3mm. It has an induction range of 22nH-680nH, allowing it to be used in a multitude of designs and applications. The circuit schematics usually denote the HA55L-3623220LF as "L" with a corresponding numeric value shown in the brackets.

In terms of its application, this type of inductor is typically used in circuits which require a larger inductance than those provided by circuit-board mounted resistors. Common electronic systems in which they can be found include radios, televisions, stereos, personal computers, and cell phones. Furthermore, the HA55L-3623220LF is also used as an energy-saving device in power supplies to reduce the amount of wasted power.

In terms of its basic working principle, the HA55L-3623220LF inductor functions as an alternating current (AC) power filter by creating an inductance in a circuit. Its working mechanism is based on the fact that when a current is injected into a conductor, a magnetic field is generated around the conductor. As the steady-state current begins to change, the magnetic field varies in a proportional fashion. This changing current induces a magnetic flux, along with a small voltage, known as the back-EMF (electro-motive force). In technical terms, it is known as Faraday’s law of magnetic induction, after the physicist who discovered it. This is the fundamental principle on which all inductors and transformers are based.

The HA55L-3623220LF consists of a continuous straight wire that is wound around a ferrite core. This wire is known as the windings, or more precisely, the inductance coil, and is designed to create a uniform level of inductance throughout the entire circuit. The amount of inductance generated by the coil is controlled by the number of turns of the wire, the distance between the turns and the type of core used.

Generally, the HA55L-3623220LF inductor provides a relatively low series impedance and a relatively low inductance compared to other inductors of its size. This makes it ideal for applications where stability is a key factor. However, its low inductance and series impedance also make it unsuitable for high-power applications such as those found in electric motors and generators.

In conclusion, the HA55L-3623220LF inductor is one of the most frequently used inductors around due to its wide use in the consumer electronics industry. It provides a low-cost solution to various applications due to its small size and varied range of applications. This type of inductor is generally used to filter out AC currents and reduce power wastage. Furthermore, its working principle is based on Faraday’s law of magnetic induction, which is the principle on which all inductors and transformers are based.
