Inductors, also commonly known as coils or chokes, are widely used in many applications, including electric and electronic circuits, communication systems, and other power electronic equipment. Fixed inductors, as the name suggests, are designed to produce an inductance that is not easily changed with unexpected current or voltage fluctuation. The HKQ04021N7B-T fixed inductor manufactured by DAESAN Electronic Co., Ltd is an example of such a device.

The HKQ04021N7B-T fixed inductor consists of an iron-based core and an enameled copper wire. It has a size of 0.4 mm x 0.2 mm, making it small compared to common inductors. The rated current for this device is 0.17 A, and the rated inductance is 1.62 nH. Moreover, its rated voltage is 2.15 V and its ESR is 5.00 mΩ.

This fixed inductor is a suitable component for use in a variety of applications that require small size and ultra-low loss. It can be used in various audio, video, telecommunications, computer, multimedia, automotive, and industrial equipment. It is also an ideal choice for high-frequency, high-density circuits where its low capacitive properties provide excellent signal transmission and minimize RF losses. This fixed inductor is RoHS compliant and meets UL 94V-0 standards to ensure reliable operating performance even in high-temperature and high-voltage industrial environments.

At the most basic level, the HKQ04021N7B-T fixed inductor works by providing a path for moving electrical current. When a current passes through the winding of an inductor, a magnetic field is created. This magnetic field adds an additional mechanical resistance to the electric current, resulting in a voltage drop across the inductor. In most cases, this voltage drop is very small and can be ignored.

In addition to this, the HKQ04021N7B-T fixed inductor produces inductance, which is a measurement of the opposition of an electric current changing its magnitude or direction over time. The inductance created by the fixed inductor is determined by its physical properties, such as size, shape, core material, and number of turns. Inductance is used to filter attenuate high-frequency electromagnetic waves, allowing electronic products to work well in environments with strong electromagnetic radiation.

In summary, the HKQ04021N7B-T fixed inductor satisfies the requirements for a wide variety of applications due to its small size, ultra-low-loss performance, and high-frequency filtering capabilities. With its excellent signal transmission and reliable working performance, this fixed inductor is an invaluable component for electrical and electronic systems.
