Fixed Inductors

Fixed inductors are an important component of any electronics system. They are used in a variety of applications including power converters, signal processing circuits, and radio frequency (RF) circuits. Fixed inductors come in various shapes and sizes, from small surface-mount to large power inductors. In this article, we will look at 79FR22M, a fixed inductor, and its application field and working principle.

79FR22M Application Field

The 79FR22M is a type of fixed inductor with an inductance of 0.22mH and a maximum DC current rating of 0.25A. This type of inductor is used in a variety of applications including power converters, radio frequency circuits, and signal processing circuits. In power converters, the 79FR22M is used to reduce the voltage ripple caused by switching elements. This is often necessary in high efficiency DC to DC converter designs. In radio frequency circuits, the 79FR22M is also used to reduce the ripple caused by switching elements and to reduce losses caused by high frequency currents flowing in switching elements. In signal processing circuits, the 79FR22M can be used to filter out unwanted signal frequencies and improve the signal-to-noise ratio.

79FR22M Working Principle

The 79FR22M has a simple working principle. When current is passed through the inductor, a magnetic field is created around it. This magnetic field resists any changes to the current flowing through the inductor, thus storing energy. The inductance of the 79FR22M is determined by the number of windings on the inductor’s core and the size of the core. The amount of energy stored in the inductor is determined by the amount of current flowing through it. The 79FR22M is an ideal choice for filtering applications where very low-level signals need to be converted to higher frequencies.

Conclusion

The 79FR22M is a type of fixed inductor with an inductance of 0.22mH and a maximum DC current rating of 0.25A. It is used in a variety of applications such as power converters, radio frequency circuits, and signal processing circuits. Its simple working principle involves the creation of a magnetic field around the inductor when current is passed through it. This magnetic field resists any changes to the current, allowing the 79FR22M to store energy. As such, the 79FR22M is well suited for filtering applications where very low-level signals need to be converted to higher frequencies.
