Fixed inductors, or rather fixed inductor coils, are components used in a variety of electronic circuits, such as radio transmitters and receivers, amplifiers and power supply circuits. Generally, they are used to store or pass electrical energy via magnetic fields, allowing for the creation of resonance circuits for tuning and filtering applications, and also in phase-shift filtering used in high-fidelity audio applications. The LQW18AN39NG80D is a particularly versatile fixed inductor, largely due to its combination of small size and large inductance value. Consequently, it is well-suited for a wide range of applications, from the power supply of components to the signal conditioning and filtering of high-fidelity audio systems.

In order to understand the application fields and working principles of the LQW18AN39NG80D, the electric, magnetic, and other parameters must be considered. The electric parameters of the LQW18AN39NG80D include inductance, DC resistance, self-resonant frequency, maximum current rating, and maximum voltage rating. The inductance, which typically ranges from 10 to 1000 µH, is significantly dependent on both inductor material and geometry. The DC resistance ranges from 0.006 to 0.09 ohms, and is also dependent on both the material and geometry of the inductor. The self-resonant frequency (SRF) of the LQW18AN39NG80D is approximately 5 GHz. The maximum current rating and maximum voltage rating, respectively, are 12 A and 100 V.

The magnetic parameters of the LQW18AN39NG80D, which include core loss, magnetic shielding, and permeability, are equally important considerations for equipment designers. The core loss is dependent upon the AC frequency in use and can range from 0.3 W to 4 W. Magnetic shielding is an important factor, as it indicates the effectiveness of the inductor in reducing stray magnetic fields. Permeability is the ratio of the energy stored by an inductor for a given current, to the energy stored by an equivalent length of an ideal AC wire loop. These parameters are important to consider when selecting the optimal inductor to suit the application.

The working principle of the LQW18AN39NG80D is essentially that of any other fixed inductor. Inside the inductor coil, an electric current creates a magnetic field which then stores energy in the form of a magnetic field. This field then reacts with incoming electrical signals, either absorbing or releasing energy in the form of a current. In most cases, inductors are used in radio-frequency (RF) applications, where they are used to filter signals and create resonance circuits. Inductors can also be used to control DC voltages in power supplies, as well as to limit current in electronic circuits.

In summary, the LQW18AN39NG80D is an excellent choice of fixed inductor for a range of different applications. Its combination of small size and large inductance value allows for its use in both power supply and signal conditioning applications. The electric parameters, such as inductance, as well as the magnetic parameters, such as core loss and magnetic shielding, must all be considered when selecting the optimal inductor for a particular application. The working principle of the LQW18AN39NG80D inductor is the same as that of any other fixed inductor, based upon the generation of a magnetic field to store energy.
