Fixed inductors, also known as output and line inductors, are usually used to reduce the effects of inrush currents during switching. As their name implies, they are inductors with fixed, predetermined sizes and values. They are commonly found in consumer electronics, such as computers, servers, routers, and other networking equipment.

The CM322522-6R8KL is a type of fixed inductor, characterized by its small size and high operating frequency. It is typically used in high-frequency power supply circuits and in DC-DC converters.

The core of the CM322522-6R8KL is made of ferrite material, which allows it to operate at high frequencies without generating excessive heat. The inductor has a rated inductance of 6.8nH, a DC resistance of 0.1ohm, and a Q factor of 78. It has a rated current of 1.1A and a rated voltage of 300V.

The primary application of the CM322522-6R8KL is in power supply or DC-DC converter circuits, where inrush current mitigation is critical. In power supply circuits, the inductor can reduce the power supply’s “inrush current” when it is switched on, thus reducing the size and number of components. In DC-DC converters, it can provide high-frequency smoothing, reduce noise, and reduce the power output ripple.

The working principle behind a fixed inductor is based on Faraday\'s law of induction, which states that a changing electric or magnetic field will induce a voltage across any conductor within it. When a CM322522-6R8KL inductor is placed in a circuit, an alternating magnetic field is induced by the current flow, which in turn induces a voltage in the inductor. This voltage opposes the current flow, thus creating a back-EMF voltage, which can be used to reduce inrush currents.

In addition to its use as an inrush current limiter, the CM322522-6R8KL can also be used as a filter or choke in DC-DC converters. Its ferrite core allows it to achieve high-frequency smoothing, which reduces switching noise and eliminates power supply ripple. This is beneficial for sensitive circuits, which may be adversely affected by power supply noise.

In conclusion, the CM322522-6R8KL is a type of fixed inductor that is used in power supply and DC-DC converter circuits. It works on the principle of Faraday\'s law of induction, and its ferrite core provides high-frequency smoothing, thus helping to reduce inrush currents and switching noise.
