Fixed Inductors

Inductors, also known as coils, are passive electrical components that store energy in the form of magnetic fields when a current is flowing through them. When the current stops, the stored energy is released. Fixed inductors are used to control the flow of currents in electronics, and their properties depend on the material, the coil structure, and the number of turns in the coil.

The PM5022S-220M variable inductor is a high-current version of the conventional PM5022S series of power inductors. It is designed for compact, high-density power conversion applications in switch mode power supplies, DC-DC converters, and many other circuit designs. The inductor operates at frequencies between 10kHz and 1MHz, and is able to handle up to 220 amps of current, making it ideal for high current applications. It is wound with a static magnetic field for added stability.

Application Field

The PM5022S-220M is suitable for applications in a wide range of industries, from automotive to consumer electronics. In the automotive industry, the inductor can be used for high-current automotive electronics, such as ignition and charging systems, oil pressure monitoring, and high-current circuit protection. In consumer electronics, the variable inductor is suitable for portable electronic devices, such as portable speakers, media players, and computers.

The inductor is also useful for many other industries, including medical, telecommunications, and aerospace. In these industries, the inductor can be used for high-current supplies, such as power systems, high-voltage protection circuits, and high frequency switching applications.

Working Principle

The PM5022S-220M is an inductor as it works on the principle of electromagnetic induction. This means that the inductor creates a magnetic field when a current passes through it. This magnetic field creates a circulating flow of current in the surrounding wire, which then creates a opposing field that opposes the original field. This opposing field opposes the original field and acts as a resistance, slowing down the current.

The PM5022S-220M is a variable inductor as it can be adjusted to provide varying levels of resistance. This is achieved through the number of turns of wire wrapped around the inductor and the type of material used. The greater the number of turns and the type of material used, the greater the resistance and the slower the current. This feature is beneficial in applications which require varying levels of resistance or current control.

Conclusion

The PM5022S-220M is a high-current variable inductor, designed for compact, high-density power applications. It is suitable for a variety of uses, from automotive to consumer electronics, and works on the principle of electromagnetic induction. By altering the number of turns and the type of material used, the inductor can be adjusted to provide varying levels of resistance, making it ideal for current control applications.
