Fixed Inductors, such as the LQW2BHNR39K03L, are highly versatile electrical components which are used in a wide range of applications from automobiles to digital systems. As the name implies, they are designed to maintain a constant inductance, or a fixed amount of electrical signal, regardless of the specific conditions the device is subjected to. These components can be found in almost any type of electronic circuit, and are used in dozens of different industries for dozens of different purposes. In this article, we\'ll be taking a look at some of the primary ways in which fixed inductors, like the LQW2BHNR39K03L, are put to use, as well as explaining the basic principles upon which their device operation is based.

Applications for Fixed Inductors

As mentioned previously, the applications for fixed inductors are incredibly far-reaching. As of yet, they have no known rival or superior in terms of versatility and efficiency in serving various functions. Here are some of the primary applications in which fixed inductors are used:

• Transformer Applications – Fixed inductors are key components for most transformer applications, where they are used to increase or decrease voltage levels and aiding in the protection of electrical circuits.
• Power Conversion Applications – Power converters also require the use of fixed inductors in order to control current and step up or step down voltage levels.
• DC-DC Converter Applications – Fixed inductors are also a vital part of DC-DC converters, where they help to direct current flow, store energy, and help regulate the output voltage.
• Automotive Applications – Fixed inductors are used in the automotive industry for a wide variety of functions, such as providing filters for audio systems and operating as power steering components.
• Electro-Mechanical Applications – Fixed inductors are also used in various electro-mechanical power transmission applications, such as in industrial motors and pumps.
• Digital Systems – The presence of fixed inductors is also required for most digital circuit boards, where they provide a stored energy source, help with signal integrity, and aid in circuit timing.

Working Principle of Fixed Inductors

In order to understand how the LQW2BHNR39K03L and other fixed inductors operate, it is first important to understand the basics of electrical and magnetic fields. Whenever there is a current flowing through a wire, it will generate a magnetic field. This field is strongest near the conductor and grows weaker as you move away from it. This is why, when two wires are placed near each other, they will start to interact and draw in one another much like a magnet.

Fixed inductors capitalize on this phenomenon by winding two or more metal wires around a magnetic core in a coil-like fashion. This coil will produce a magnetic field that is much stronger than if two wires were placed right next to each other. Consequently, this field can pass through other wires which helps to induce a current in them. In this manner, the fixed inductor helps to increase the voltage of a circuit, as well as storing energy. Additionally, fixed inductors also act as filters, blocking unwanted signals from entering and leaving a system.

When selecting a fixed inductor for a particular application, there are several key characteristics which determine its capabilities. Parameter values such as its inductance, resistance, and current carrying capacity are all critical for proper operation. Additionally, knowing the frequency range which the device can operate at is also important, as this determines exactly what type of applications the device can be used for. Also, some fixed inductors use an electrically activated switch in order to change their configuration when a certain voltage is reached, which is key for some applications.

Conclusion

Fixed Inductors, such as the LQW2BHNR39K03L, are highly versatile components which are used in a variety of different industries and applications. By utilizing the mechanical induction effects inherent to stationary wires placed around a magnetic core, fixed inductors can increase voltage, store energy, and filter electrical signals. As such, they are essential building blocks for devices ranging from transformers to digital circuits. Knowing the critical parameters which consider the fixed inductor\'s performance is key to properly using them in any given application.
