Fixed Inductors are a type of passive electronic component that produces a steady magnetic field when current passes through them. An example of a fixed inductor is a DR74-470-R (DCR), which is a four-terminal device with two terminals at each side. The fixed inductor is connected in series with a DC voltage source.

The DR74-470-R is commonly used in applications such as low-cost power supplies, DC-DC converters, motor drives, and power management for laptops and other mobile devices. As their name implies, these fixed inductors are fixed, as opposed to variable inductors, and can maintain a steady magnetic field regardless of the amount of current flowing through them.

The working principle of a fixed inductor is relatively simple and straightforward. When a current passes through the inductor\'s terminals, an electromotive force is produced, which causes the magnetic field to become stronger. This magnetic field is then maintained by the electrons being continually spun in a circle. The resulting constant magnetic field can be used to induce a voltage or current in an adjacent circuit.

In addition to its magnetic field, the DR74-470-R also has a self-air-gapped property. This means that it can be operated without forming an electrical circuit, allowing it to be used in applications where it would not be feasible to utilize conventional inductors.

The DR74-470-R fixed inductor is a fairly versatile device, as it can be used in a variety of different applications. It is ideal for use in small, low-current applications in which a steady magnetic field is required. It is also suitable for use in larger applications such as motor drives, DC-DC converters, and power supplies.

Overall, the DR74-470-R fixed inductor is a useful and versatile device that can be used in a variety of applications. Its steady magnetic field makes it ideal for use in low-current applications, while its self-air-gapped property allows it to be used in larger applications where it would not be feasible to utilize conventional inductors.
