Fixed inductors are electronic components that are used to store energy in the form of a magnetic field. They are made up of a series of coils and conductors, encapsulated in a plastic or metal casing. The 47681SC is a popular fixed inductor, often used in consumer electronic applications.

This component is a surface-mount component, which is why it is often used in consumer electronics, as it offers a very small form factor. The inductor is capable of operating at a frequency of up to 1 MHz, while providing inductance ratings from 1.5 µH to 68 µH. It also has a very low DC resistance of up to 4.5Ω. It is available in a variety of packages, and in many cases, can also be found in through-hole configurations, for those who require a higher degree of reliability of connection over time.

The 47681SC can be used in a variety of different applications. As an inductor, it is capable of creating a magnetic field that can be tapped to generate power, or can be used to store energy in a variety of ways. It is often found in power management circuits, where it can be used to help regulate the flow of current. It can also be used in filtering circuits, as well as in digital signal processing applications, where it can be used to create delays or sync signals. It can also be used in communication systems, as an RF choke, allowing signals to be safely isolated from one another, and preventing cross-talk.

As a fixed inductor, the 47681SC has a relatively simple working principle. Current is applied to the inductor, which in turn induces a magnetic field in the surrounding environment. The EMI shield on the component prevents potential EMI interference from affecting the magnetic field, and also helps to ensure that the inductor is safe from current surges. The stored magnetic field continues to build, until the current is turned off, causing the field to collapse, releasing the stored energy.

In summary, the 47681SC fixed inductor is a popular component used in consumer electronics due to its small form factor. It offers inductance ratings from 1.5 µH to 68 µH, with a low DC resistance of up to 4.5Ω, and is capable of operating at frequencies of up to 1 MHz. It can be used in a variety of different power, signal processing, and communication applications, and works by inducing a current and creating a magnetic field, which can be tapped to output usable electricity, or stored. The EMI shield on the device helps to prevent unwanted interference.
