Fixed inductors are frequently used in power electronic circuits because of their ability to store electrical energy. When an alternating current passes through a fixed inductor, the inductor stores electrical energy in the form of an ever-increasing magnetic field. This stored energy is then released in a step-wise manner as the frequency of the alternating current changes.

The HKQ0603U0N7B-T, an example of a fixed inductor, is a surface-mount inductor with a maximum DC resistance of 0.04 ohms. It has a rated current of 4A and can operate up to 125℃. The inductance of this inductor is from 0.47µH to 5.6µH and it can deliver up to 12A of peak current.

The application field of HKQ0603U0N7B-T is mainly in LED, LCD, and LED lighting circuits such as backlighting, and surge protection. The device is designed for secondary side flyback applications and it can also be used for frequency, selectivity, and filter blocks, as well as high performance buck converters. The inductor also has applications in DC-DC converters and buck-boost converters, along with power security. Furthermore, the device has applications in board-level EMC filters, signal filters, and AC/DC block filters.

The working principle of HKQ0603U0N7B-T is very simple. When the current through the inductor changes, an opposing EMF is induced. This opposing EMF works against the original EMF, causing the current to slow down. The result of this is that, for a fixed inductor, when the current through the inductor is increasing, the current drops and when the current is decreasing, the current is increased. This allows the inductor to act as a filter, allowing only AC frequencies below its cutoff frequency to pass and rejecting any AC frequencies higher than its cutoff frequency.

The HKQ0603U0N7B-T is a great example of a fixed inductor that can be used in numerous modern-day applications. With its ability to store electrical energy in the form of an ever-increasing magnetic field, it is able to be used in anything from LED lighting to surge protection. Understanding the working principle of the HKQ0603U0N7B-T enables engineers to utilize the device to its full potential.
