Fixed Inductors

A fixed inductor is an electronic component that stores and maintains electrical energy in a magnetic form, usually in the form of a coil of wire. This stored energy enables the inductor to act as an electrical filter, performing functions such as transforming AC to DC, providing a time delay, and so on. Among the most popular types of fixed inductors are the 3090-822H type. In this article, we will take a closer look at the application field and working principle of the 3090-822H inductor.

Application Field

The 3090-822H inductor is mainly used in DC-DC converter, voltage regulator, and power supply applications. This type of inductor is usually used in conjunction with a transformer to provide a regulated output voltage level. It is well-suited for use as a DC-DC voltage booster, providing higher voltage output than the input voltage. In a voltage regulator application, it is typically used for providing a stable voltage reference, which helps to reduce output voltage variations. The 3090-822H is well-suited for high efficiency applications due to its high power rating. It has low leakage of magnetic flux, so there is minimal energy lost due to self-induction.

Working Principle

The 3090-822H inductor works by storing magnetic energy in the form of a magnetically coupled current loop. The inductor comprises two wires, one winding and another sensing winding; the two windings are connected to each other magnetically, rather than electrically. The two windings are also separated by a core. When the primary current flow through the primary winding, a magnetic field is produced, which is coupled to the secondary winding. This produces an induced current in the secondary winding, which helps to increase the load current.

When the current flow through the inductor is continuous, the magnetic field and induced current add together, giving an average value of the load current. This is known as the average value of inductance. When the current flow is discontinuous, the magnetic field and induced current alternately subtract and add together, giving the actual inductance value of the load current. The inductance value changes when the current level changes, therefore the current through the inductor has to be held steady by a regulating device.

The 3090-822H inductor is capable of delivering high output power and fast current rate, making it an ideal choice for applications where precision current regulation is essential. It also has a wide temperature range, making it suitable for a variety of applications.

Conclusion

The 3090-822H inductor is a popular fixed inductor. It is capable of delivering high output power, fast current rate, and has a wide temperature range. The 3090-822H inductor is mainly used in DC-DC converter, voltage regulator, and power supply applications. It works by storing magnetic energy in the form of a magnetically coupled current loop. With its high efficiency and adaptability, this type of inductor is an ideal choice for applications requiring precision current regulation.
