Fixed Inductors

Fixed inductors, also known as fixed coils, are electric components that have a specific number of turns of copper wire wound to form an inductor. The turns of wire in the inductor form a loop which concentrates the inductor’s magnetic field. The inductor’s inductance is determined by the number of turns and the loop’s size. Typically, inductors come in a variety of shapes including axial, radial, and surface mount designs. Inductors are resistive components, meaning, they oppose the flow of alternating current and create a back voltage in the opposite direction.

Inductors find applications in many electrical circuits and products. Their primary function is to store energy in the form of a magnetic field, allow current to flow in one direction, limit the rate of current flow, reduce the width of pulses, and filter high-frequency signals from low-frequency signals.

LQH43MN470J03L Application Field And Working Principle

The LQH43MN470J03L is an axial inductor manufactured by Murata. It has a maximum DC resistance of 4.702 ohms, a current rating of 12.6 amperes, and an inductance range of 470nH ± 20%. The rated temperature range is -40 to +125°C. Due to its high current rating, the LQH43MN470J03L is suitable for use in automotive and industrial applications.

The working principle of an inductor is based on a law of electromagnetism known as Faraday\'s law. According to Faraday\'s law, when an electric current passes through a conductor, an electromagnetic field is generated around it. When the electric current increases or decreases, the magnetic field around the conductor also changes. This change in the magnetic field induces an electromotive force in the conductor and a current (which is proportional to the rate of change of the current) flows in the opposite direction. This is basically how an inductor works. Inductors are used to allow current to flow in one direction while limiting the rate of current flow in the opposite direction.

The LQH43MN470J03L can be used as an inductor in a variety of electrical circuits and products, such as power supplies, switching converters, and filter circuits. It can also be used in DC/DC converters, AC/DC converters, and automotive systems. Since the LQH43MN470J03L has a temperature rating of -40 to +125°C, it is suitable for use in extreme temperature environments.
