Fixed Inductors: 1225AS-H-4R7M=P2 Application Field and Working Principle

Fixed inductors, also known as chokes, are electronic components used to resist current and can store electrical energy due to their inductance. This particular type of component, the 1225AS-H-4R7M=P2, has a wide variety of application fields, as well as an interesting working principle.

Application Fields of 1225AS-H-4R7M=P2

The 1225AS-H-4R7M=P2 is a widely applicable fixed inductor, popular among a variety of industries. This inductor is most commonly used in dc-dc converters, ac-dc rectifiers, power supplies, RF and audio filters, audio-frequency circuits, single-phase and three-phase inverters, and uninterruptible power supplies. Additionally, it is often employed in automotive and other applications involving environments with high-temperature and vibration.

This specific device is mostly preferred in applications where a high current with low impedance is necessary. Its design helps to reduce noise, which is desirable when building audio systems or consumer electronics. Furthermore, it offers galvanic possibilities in medium-frequency applications, due to its self-shielded construction that allows mounting without the use of ferromagnetic material.

Working Principle of 1225AS-H-4R7M=P2

The 1225AS-H-4R7M=P2 fixed inductor works on the principle of Faraday\'s law of inductance. This law states that when a wire coil has current running through it, it produces a magnetic field. This magnetic field, due to this induced current, creates a back EMF (electromagnetic force) that opposes the current.

In the case of a fixed inductor, the current carrying coils of wire create the same magnetic field, however when a fixed inductor is disconnected from a source voltage, the back EMF produced by the internal magnetic field will cause the current to decrease gradually to the zero level. This is because the back EMF opposes the current, and so the opposition decreases, resulting in a decrease of current.

Fixed inductors, especially the 1225AS-H-4R7M=P2, are widely applicable due to their current resistance and low impedance. Additionally, this specific device is designed to reduce noise and offers galvanic possibilities in medium-frequency applications.
