HKQ04021N6S-E

Fixed inductors are components that allow the passage of electrical current through them, with minimal losses as the current moves through it. In this regard, they are mainly found in electrical circuits, where their role is to maintain a given amount of electric charge at a given value. The HKQ04021N6S-E is a particular model of fixed inductor that is used in numerous applications where reliable performance is required. Below, we explore the applications and working principles of this component.

Applications

The HKQ04021N6S-E is primarily used in power supplies, voltage converters, and pulse circuits. In power supplies, it is used to store energy and maintain a steady current between the input and output. This ensures that power is distributed effectively throughout the system. In voltage converters, this inductor helps to transform and regulate voltage between the input and output. Finally, the pulse circuits employ this component to condition electrical signals and ensure that they are of the correct shape and lower level.

Working Principle

The working principle of the HKQ04021N6S-E is based on the principles of electromagnetic induction. This states that a changing magnetic field will induce electric current to flow through an inductor. This type of inductor consists of a coil of wire wound around a core. The core is traditionally made of ferromagnetic material to give it higher inductance. When a steady electric current is applied to the inductor, a magnetic field is created by the wires within the coil. This magnetic field then interacts with the core to form an inductance.

In operation, when the current through the HKQ04021N6S-E changes, the magnetic field in the coil will overlap with the core’s magnetic field, increasing the inductance. The increase in inductance then acts to resist the changing current, creating an opposition to the current flow known as "back EMF". This has the effect of maintaining the current at a stable level, preventing it from rising too high or dropping too low. This makes the HKQ04021N6S-E perfect for regulating power, voltage conversion, and pulse applications.
