HC8LP-R15-R

Fixed Inductors

A fixed inductor is an electronic device consisting of a coil of insulated wire usually in a cylindrical form. It is also known as a coil or choke. It stores energy in the form of a magnetic field when electricity is flowing through it. The main purpose of a fixed inductor is to provide a nearly constant current or voltage at a given frequency, and it is found in a variety of applications within our technological world.

One example of a fixed inductor is the HC8LP-R15-R. It is a low cost, Power Inductors. Having an inductance of 15uH with a maximum current of 20A, this Power Inductors can be used in many different applications.

HC8LP-R15-R Application Field and Working Principle

The HC8LP-R15-R is most commonly used in switch mode power supplies (SMPS) and switching converters. In such an environment, it is often used in DC-DC converters to regulate the output voltage in applications such as electric vehicles, battery-powered devices, and robotics. In addition to being used in switch-mode power supplies, these inductors can also be found in voltage-regulated DC-DC converters, pressure-responsive alarms in fire safety systems, automotive braking systems, and audio-signalling devices.

The basic working principle of a fixed inductor involves the interaction of an electric current with a magnetic field. Electrons in the wire coil generate an electromagnetic field, and this field interacts with the current to produce an induced back-EMF or electromotive force. This force works against the current flow and helps to reduce any fluctuation in the current. At a steady-state, the two opposing forces balance one another out, and a constant current flows through the inductor.

The inductor’s ability to generate and maintain a constant current is due to its self-inductance, which is determined by the inductor’s “geometric” parameters. These parameters include the number of turns in its coil, its length, and its diameter. An inductor with a higher number of turns or a larger diameter provides greater self-inductance and, therefore, greater current stability.

Inductors play an important role in many electrical and electronic devices, providing the needed current or voltage to power the device or carry out its intended purpose. The HC8LP-R15-R inductor is a prime example of how these inductors are used in the modern world for a variety of applications.
