Fixed inductors are electrical components designed to store electrical energy as a magnetic field in a certain amount. There are a variety of inductors, but 100-821G application field and working principle are quite unique.

The 100-821G inductor is specifically designed for power supply applications. It has low electrical impedance, which makes it ideal for use in high power circuits. The inductor consists of a coil wrapped around a core made of magnetic material. The core stores the magnetic field generated by the current through the coil. This magnetic field creates a back-emf (electro-motive force) which acts as a voltage across the coil when the current through the coil decreases. This back-emf maintains the voltage of the power supply and, hence, allows more efficient power conversion.

The working principle of the 100-821G inductor is the reverse of a transformer. In a transformer, an alternating electric signal passes through a coil which then induces voltage in a secondary coil. This is known as electromagnetic induction. In the case of an inductor, an alternating electric signal passes through a coil which creates a magnetic field that is stored in the inductor core. When the alternating current decreases, the magnetic field collapses and a voltage is created across the coil to maintain power.

The 100-821G inductor is primarily used in power supplies, especially those with high power demand. The inductor is able to store energy as a magnetic field which is then used to reduce power fluctuations and ensure a smooth supply. Additionally, the inductor also acts as a filter, blocking high frequency signals and providing a cleaner supply. As such, the inductor is becoming more and more necessary in modern power supplies.

For all its merit, the 100-821G inductor has some limitations. First, the inductor can experience flux leakage which will reduce its effectiveness. Similarly, excess heat can damage the core, reducing the life expectancy of the component. To minimize these effects, it is important to ensure proper installation and use of the inductor.

In conclusion, the 100-821G inductor is a unique electrical component specifically designed for power supply applications. Its working principle is based on the reverse of a transformer, with an alternating current passing through a coil creating a magnetic field which is stored in the inductor core. The inductor is mainly used as a power stabilizer and filter in high power circuits. Despite its merits, it is important to be aware of the possible damage caused by flux leakage and excessive heat caused by improper installation and use.
