Fixed inductors are passive components used in a variety of different circuit applications. They are used mainly to store energy in the form of an electromagnetic field between conductors that can later be released for use. Inductors come in many different shapes and sizes, from air core inductors to ceramic core inductors. The subject of this discussion is the application field and working principle of LQW18ASR20J0ZD, a type of fixed inductor.

The LQW18ASR20J0ZD is a surface mount fixed inductor designed for use in high speed digital circuits. The inductor is made of a copper wire core wound with a ferrite shell. Its size is 1812 and it can operate up to 20 MHz. It offers a high inductance value of 33 nH ± 5% and a low DC resistance of 0.34 Ohm. The rated DC current for it is 3.0A.

The application field of the LQW18ASR20J0ZD includes high frequency amplifiers, power supplies, power converters, switch mode power supplies, and high frequency communication systems. The device is suitable for use in a wide variety of circuits, due to its high inductance and low resistance. In power supplies, inductors help provide electrical filters that can reduce electrical noise. In high frequency communication systems, the inductor helps reduce interference that can cause poor signal quality. In high frequency amplifiers, the inductor helps provide high power efficiency, as well as a good signal-to-noise ratio.

The working principle of the LQW18ASR20J0ZD can be explained in terms of impedance. When an alternating current passes through the inductor, it generates an electromagnetic field around the inductor, and this in turn generates a magnetic field. This magnetic field induces a voltage across the inductor, and the inductor will then hold this voltage, or an impedance, until the current passes through it again. The impedance of the inductor will increase as the frequency increases, and will decrease as the frequency decreases. The behavior of the inductor is dependent on the number of windings around the core and the core material, which is why the LQW18ASR20J0ZD has a ferrite shell. Because of the high inductance value, the inductor can store a large amount of energy, making it ideal for high frequency applications.

The application fields and working principles of the LQW18ASR20J0ZD fixed inductor make it a versatile component in high frequency circuit applications. Its high inductance and low resistance make it suitable for a variety of different circuits, from power supplies to high frequency amplifiers. Its size and high operating frequency make it suitable for high speed digital circuits. As a result, the LQW18ASR20J0ZD is an ideal choice for a wide range of circuit applications.
