Fixed Inductors

Inductors, also called coils and sometimes chokes, are one of the most important components used in electrical circuits. A fixed inductor is an electrical component that provides a certain amount of inductance in a circuit. Fixed inductors can be used in a wide variety of applications from radio-frequency (RF) circuits to AC and DC power supplies.

The ATFC-0201HQ-0N5B-T is a fixed inductor, specifically designed for use in power supplies. It features low profile, 2.0mm maximum height, low RDC, and low magnetic emission. It has a wide range of inductance from 20µH to 1200µH, which makes it suitable for many different applications.

In order to understand the working principle of a fixed inductor, it is important to first understand how an inductor works. An inductor is an electrical component that stores energy in a magnetic field. When current passes through the inductor, the magnetic field that is created is proportional to the amount of current. This magnetic field is associated with a certain amount of inductance, which is measured in henries (H).

Now let\'s take a look at how the ATFC-0201HQ-0N5B-T fixed inductor works. When a voltage is applied across its terminals, a back EMF is created which opposes the applied voltage, thus the current through the inductor will decrease. This is due to the inductance of the component, which causes a voltage drop across its terminals.

The ATFC-0201HQ-0N5B-T fixed inductor is commonly used in power supplies, due to its excellent performance and low losses. It is also used in RF circuits, such as switching power supplies, and in AC or DC power converters. It can also be used in different types of filters, such as high-pass or low-pass filters.

In addition to the ATFC-0201HQ-0N5B-T fixed inductor, there are several other fixed inductors on the market. However, each inductor has its own range of inductance and characteristics, so it is important to select the appropriate inductor for the specific application. In general, for a power supply application, it is important to select an inductor with low DCR (resistance) and high frequency performance.

In conclusion, the ATFC-0201HQ-0N5B-T fixed inductor is an excellent choice for many applications, including power supplies, RF circuits, AC or DC power converters, and filters. Its low DCR, low profile, low magnetic emission and wide range of inductance make it a great option for a variety of applications. The working principle of a fixed inductor is easily understood: when a voltage is applied across its terminals, a back EMF is created which opposes the applied voltage, thus causing a decrease in current through the inductor.
