Fixed inductors are electronic components that use a coil of wire to store energy in the form of a magnetic field. They are widely used in power supplies, switching converters, and signal processing applications. A common type of fixed inductor is the two-pin, two-contact, 2256-681K. This type of inductor is well-suited for applications where relatively low inductance and small size are desired.

The 2256-681K is a small three-dimensional construct living in a tiny 0.215" by 0.235" package. It can store up to 6.81 millihenries of inductance and has a low Q rating of 9 @ 500 kHz. This means that the inductance will decline rapidly as frequency increases. Its reactance value drops rapidly at higher frequencies, making it ideal for applications such as RF power supplies.

The working principle of a fixed inductor is quite simple. When electric current passes through the coil, a magnetic field is generated around it. This magnetic field attracts and repels the electrons in the coil, causing them to move. As they move, they generate another magnetic field in the form of a loop. The loop of magnetic energy created by these electrons, a phenomenon known as induction, is the basis of operation for any fixed inductor.

The 2256-681K\'s application field is varied and includes switching converters, high voltage power supplies, high frequency amplifiers, and other RF circuits. Its low inductance, compact size, and low Q rating make it suitable for a wide range of applications. For power supplies, it provides useful filtering capabilities, allowing for efficient regulation. In high-frequency amplifiers, it serves as a broadband device, providing gain under a wide range of frequencies. Operational frequency makes it also suitable for RF circuits.

The 2256-681K is a dependable and versatile fixed inductor. It provides a reliable solution for projects that require tight tolerances and small size, and is well suited for applications such as power supplies, signal processing, and high-frequency amplifiers. Its wide range of possible applications have made it a popular choice for engineers and designers who need a reliable and cost-effective solution.
