4922-22L

Fixed Inductors

The 4922-22L is a kind of fixed inductor which is mainly used in switching power supplies, DC-DC converters, low noise amplifiers, automatic test equipment, and various consumer electronics. It is available in a variety of sizes and is suitable for various current and voltage applications.

Working Principle

An inductor is a device that stores energy in the form of a magnetic field. It consists of a coil of wire, often wrapped around a ferrite core or other magnetically permeable material, whose purpose is to form a loop of current that cannot be broken by an external influence. When current passes through the inductor it creates a magnetic field inside the coil, which then induces an electromotive force in the opposite direction. This EMF causes a counter-current to flow in the opposite direction, which is known as the back EMF. This back EMF is what prevents an inductor from allowing an infinite amount of current to flow and is the basis for the working principle of a 4922-22L fixed inductor.

Application Field

As mentioned previously, the 4922-22L is typically used in switching power supplies and DC-DC converters. The main advantage of the fixed inductor is that it maintains the same inductance regardless of the applied current. This makes the fixed inductor suitable for applications where the current requirements may change. It is also suitable for applications requiring the power to be supplied in a constant current format, such as distributed bus systems.

The 4922-22L is also commonly used in automatic test equipment. It is capable of providing power to the system in a controlled manner and can also be used to measure current in the system. The accuracy of the measurements can be increased when the fixed inductor is used in conjunction with a shunt resistor.

Finally, the 4922-22L is also used in many consumer electronics applications such as cell phones and other portable devices. It is capable of providing power to these devices in a very efficient and consistent manner, helping conserve energy.

In summary, the 4922-22L is a kind of fixed inductor which is suitable for a variety of applications, including switching power supplies, DC-DC converters, low noise amplifiers, automatic test equipment, and consumer electronics.
