Fixed inductors are electronic components that store energy in the form of an electric field or magnetic field. They are used to create a direct current (DC) in a circuit and are often referred to as coils or chokes. The 4470-18J is one such fixed inductor, designed for a wide variety of applications. This article provides a brief overview of the 4470-18J’s application fields and working principle.

Application

The 4470-18J is a high-performance, low-profile fixed inductor that provides the best performance in a wide variety of applications. It is well-suited for use in power-supply, high-frequency switching, and communication circuits. It is also suitable for use as an EMI filter and in high-speed signal processing or high-density power circuits. Additionally, it can be used in both AC and DC circuits.

The 4470-18J is typically used in boost converters, buck converters, SEPIC converters, and industrial inverters in a variety of consumer electronics, such as telephones, computers, and LCD TV sets. In medical equipment, it is used in snubber filters and storage capacitors. It is also used for wireless and optical communication applications, as well as for apparatus and electronic circuits for security systems and motor control.

Working Principle

The 4470-18J is a fixed inductor with a ferrite core that consists of two parts: a conductive winding and an inductive core. The inductive core stores energy as a magnetic field when current is applied to the winding. The amount of energy stored in the inductor is proportional to the number of turns of the winding and to the magnetic field strength in the core.

When alternating current (AC) is applied to the winding, the core generates a magnetic field, which induces an opposing electromotive force (EMF) in the winding. This back-EMF causes the current to flow back and forth, creating an alternating current inside the inductor.

This alternating current gives rise to a magnetic field in the inductor, which then interacts with the external circuit. This interaction causes a voltage to appear across the terminals of the inductor. This voltage will have the same frequency as the applied voltage, but it will be slightly out of phase. This out-of-phase voltage is known as inductance.

In summary, the 4470-18J is a low-profile, high-performance fixed inductor suitable for a wide variety of applications. It utilizes a ferrite core to store energy as a magnetic field and produces an electromagnetic force when AC is applied to it. This back-EMF creates an alternating current in the inductor and causes a voltage to appear across its terminals, which is known as inductance.
