LQW18AN28NG80D

Fixed inductors, or inductors, are electrical energy transfer units in electronic circuits, and are widely used for different purposes, such as filtering, magnetic field creation, voltage regulation, and so on. The LQW18AN28NG80D is a surface mount inductor, and its application field and working principle will be discussed in this article.

Application Field

The LQW18AN28NG80D is a small, surface mount inductor, suitable for SMD assembly applications. It is specially designed for medium/high current and medium/high power supply applications, such as power-line conditioning, DC-DC converters, voltage regulators, and switching power supplies (in the form of power modules). It has an inductance value of 18nH up to 28nH, with a Current Sense Frequency (CSF) of up to 80kHz. It also has a Q value of up to 7.5, and an operating temperature range of -40C to +120C.

Due to its design, the LQW18AN28NG80D is perfect for high current applications, such as motor drives, stereo amplifiers, and LED lighting. It is also suitable for use in a variety of other applications, such as radio controlled toys, power-line communication, microwave ovens, and even some consumer electronics.

Working Principle

The LQW18AN28NG80D\'s working principle is based on the principle of raising or lowering the voltage in electric circuits. Basically, it increases or decreases the magnitude of current in a circuit. It does this by forming a closed magnetic loop within the inductor, which is then able to store energy in the form of a magnetic field. Since the inductor is connected to an external circuit, it is able to transfer this energy to the circuit.

The LQW18AN28NG80D is also able to regulate the flow of electricity in the circuit, by adjusting the inductance of the inductor. By adjusting the amount of current flowing through the inductor, it is possible to reduce or increase the amount of energy that is stored in the magnetic field. This is especially useful for controlling the output voltage of power supplies.

In addition to this, the LQW18AN28NG80D is also able to reduce radio frequency interference, by offering protection from external EMI (electromagnetic interference). This means that it is suitable for applications that require reduced interference with other electronic components.

Conclusion

The LQW18AN28NG80D is a small, surface mount inductor, specially designed for medium/high current and medium/high power supply applications. It is perfect for high current applications, such as motor drives, stereo amplifiers, and LED lighting. In addition, it is able to regulate the flow of electricity in the circuit, and provides protection from external EMI (electromagnetic interference). Therefore, it is a suitable option for applications such as power-line conditioning, DC-DC converters, voltage regulators, and switching power supplies, making it a great choice of inductor for such applications.
