A fixed inductor is an electronic component that is used to store energy temporarily in the form of an electromotive force. It is composed of a coil made from one or more turns of wire that, when connected to an alternating current (AC) or direct current (DC) source, creates a varying magnetic field within the coil, which induces a varying electromotive force within the same coil. The resulting field is static in nature, meaning that the energy stored within the device remains constant until the source is disconnected.

The PM5022-471M fixed inductor is designed for AC/DC applications such as new energy power supplies, motor drives, LED lighting and electronic loads. It has a high current rating, high inductance stability, low DC resistance, low power consumption, and low EMI noise. The device is a shielded structure with a higher inductance rating than most other types of inductors, making it ideal for applications where a large amount of power is required.

The working principle of a fixed inductor is based on the electricity-related properties of inductive reactance and inductance. Inductive reactance is the opposition that is encountered when an alternating current is conducted through an inductor. This opposition is the result of a changing magnetic field that is created when a varying electrical current passes through the wire coil of the inductor. By using different size coils and/or a higher current, the amount of reactance can be increased.

Inductance is the measure of a component\'s ability to store energy in the form of a magnetic field. The magnitude of inductance produced by a fixed inductor is determined by either the number of turns of wire that make up the coil or the physical size of the coil. For example, inductors with more turns of wire will possess a higher inductance rating. The field created by the coil of a fixed inductor will induce an electrical voltage, which will be used to store the energy in the form of a magnetic field.

The PM5022-471M fixed inductor has a high rated current and an inductance rating of 4.7uH. It also features a low DC resistance, which provides higher power efficiency, and low-noise operation. Other features of this inductor include its compact size, low profile, high-temperature stability, and excellent surge capability. As such, it is suitable for a wide variety of new energy and LED lighting applications.

To conclude, the PM5022-471M fixed inductor is an ideal choice for applications such as new energy power supplies, motor drives, LED lighting, and high-power electronic loads. It features a high current rating, high inductance stability, low DC resistance, low power consumption, and low EMI noise. Additionally, the device is of a shielded structure, which makes it ideal for installations with a large amount of power requirements.
