Fixed inductors are a type of electrical component that helps direct and control the flow of electric current. The SCR74B-221 is a type of fixed inductor used in a wide range of applications. It is designed to provide excellent stability and durability as well as reliable performance.

The SCR74B-221 is a through-hole axial inductor and is capable of handling up to 220mA of current. The inductance is 4.7µH plus or minus 10% at 100kHz and 10mVrms. The operating temperature range of the part is -25°C to +125°C.

The SCR74B-221 is particularly well suited for use in DC-DC converters and other related applications due to its high accuracy, wide current range, low profile, and consistent operation. It is also capable of withstanding harsh environmental conditions and is able to withstand up to 240VAC test voltage. This ensures it will be able to work reliably in a variety of applications.

The working principle of the SCR74B-221 is based on the fact that when an electric current passes through a coil of wire, it produces a magnetic field. This magnetic field is what causes the inductance to be created in the inductor. This is essential in order to help regulate the current flow in electrical circuits, and it helps maintain a constant voltage level.

The SCR74B-221 has a wide range of applications, including power supplies, inverters, chargers, DC motors, power transmission systems, and more. It can also be used to reduce radio interference, minimize power losses, and improve the efficiency of DC-DC converters. Additionally, the SCR74B-221 is often used to act as a buffer between audio and video signals, helping to reduce noise and distortion.

In summary, the SCR74B-221 is a type of fixed inductor that is designed to have excellent stability and reliability while also providing wide current range and high accuracy. It has a range of applications, from power supplies to audio and video signals, and its working principle is based on the fact that an electrical current passing through a coil of wire produces a magnetic field. This inductance helps regulate and control the current flow in electrical circuits, as well as providing a consistent voltage level. All of these features make the SCR74B-221 an excellent choice for a variety of applications.
