Fixed inductors are electrical components that store energy in a magnetic field and are used in many types of electronic circuits. The ELJ-DA390JF is a type of fixed inductor that is characterized by its small size and high efficiency. It is commonly used in power supplies, communication systems, and other high-power applications where a compact and efficient inductor is required.

The ELJ-DA390JF is a shielded, through-hole inductor that is designed for surface mounting. It has a high inductance value of 390uH with a DCR rating of 0.6 ohms. The inductor is also rated for a maximum current of 3.45A and has an SRF value of 195MHz. The inductor is RoHS compliant and is available in three different versions. The first two versions have two or three pins respectively, and the third version has four pins.

The performance of the ELJ-DA390JF is optimal when coupled with a DC-DC converter as it is a low-profile inductor that provides excellent efficiency, low EMI emissions, and high power density. It is also designed to withstand high temperature environments and is suitable for automotive, industrial, and military applications. Additionally, since it is designed to draw low current, it is also well suited for low-power applications and is often used in battery-operated devices such as medical equipment.

The working principle of the ELJ-DA390JF is based on Faraday’s law of induction which states that when an electric current passes through a coil, the coil will produce a magnetic field which in turn will produce a voltage proportional to the rate of change of the magnetic field. This voltage can then be used to drive a load such as a motor or a light bulb. The ELJ-DA390JF is designed to operate at frequencies up to 3kHz and is designed to reduce the effects of parasitic capacitance.

In summary, the ELJ-DA390JF is a highly efficient, through-hole, low-cost, shielded inductor that is designed for applications with high power demands. It is ideal for use in DC-DC converter circuits, as it provides high efficiency, low EMI emissions, and a high power density. Additionally, its low current draw makes it suitable for low-power applications, and its suitability for harsh environments makes it suitable for automotive, industrial, and military applications. The ELJ-DA390JF is based on Faraday’s law of induction, providing an efficient way to store and release energy through a magnetic field.
