22R155C Fixed Inductors Application Field and Working Principle

The 22R155C is a fixed inductor from the 22R series manufactured by Knowles. It is used in a wide range of electronics including amplifiers, power supplies, audio equipment, consumer electronics, diagnostic equipment, general purpose circuits, power circuits, and other applications. The 22R155C has an inductance of around 150 µH and a reverse current rating of around 240 mA.

In order to understand the application and working principle of the 22R155C fixed inductor, it is important to understand the core concepts around inductors. An inductor is an electrical component made of a coil of wire which stores energy in the form of a magnetic field when an alternating current is passed through it. This stored energy is then released in the form of a reverse current when the alternating current is stopped.

An inductor has different characteristics which determine its performance. The characteristics include its inductance, reverse current rating, and its rated current. The inductance is the amount of energy that can be stored in the inductor and is measured in µH. The reverse current rating is how much current can be released from the stored energy and is measured in mA. The rated current is the current the inductor needs to operate without damage and is normally measured in A.

In terms of its application, a 22R155C inductor can be used to create circuits with very low voltage drop to prevent loss of power. It can also be used to filter high-frequency signals out of low-frequency signals, such as in radio receivers and television. It can also be used to create power factor correctors and to delay the turn-off of power in LED lighting.

The working principle of a fixed inductor is fairly straightforward. When an alternating current is passed through the inductor, a magnetic field is created which will store energy. When the current is stopped, the stored energy is released as a reverse current. This reverse current can be used in many different circuits and applications.

In conclusion, the 22R155C fixed inductor from Knowles is a versatile component which can be used in a variety of applications. Its high inductance and reverse current rating make it a great choice for many power-related applications. Understanding the core concepts of inductors, in addition to its applications and working principle, will help designers make the best choices when selecting components for their projects.
