Fixed inductors are devices that store electrical energy as a magnetic field when electric current passes through them. These inductors are used in many electrical and electronic applications, such as power supplies, DC-to-AC inverters, filters, matching networks, and RF circuits. The ELJ-FD1R8KF is a common fixed inductor from the ELJ series and is used in various applications. It has a lower DCR (direct current resistance) compared to other inductors in the same series and is able to handle much more current than others. In this article, we will discuss the application field and working principle of the ELJ-FD1R8KF.

The ELJ-FD1R8KF is a surface-mount (SMT) fixed inductor that is used in a variety of applications, including power supplies, DC-to-AC inverters, filters, matching networks, and RF circuits. It is designed with an increased inductance value, low DCR, and superior high frequency performance when compared to other SMT inductors in its class. The ELJ-FD1R8KF can handle a peak current of up to 8A and a maximum temperature of 125°C. It offers excellent field uniformity, low profile, and is compatible with ROHS and WEEE compliant requirements.

The ELJ-FD1R8KF has an inductance rating of 1.8mH. This rating is determined by a physical equation that expresses the total amount of inductance provided by the ELJ-FD1R8KF. It is calculated based on the size and shape of the inductor’s windings and the number of turns in the winding. The inductance remains the same, regardless of the amount of current being passed through the device. The ELJ-FD1R8KF also has a DCR (direct current resistance) rating of 0.045Ω. This rating is determined by the amount of resistance that the device has to AC signal currents passing through it. The inductance and DCR ratings of the ELJ-FD1R8KF are important factors when determining how the device will perform in the application.

The working principle of the ELJ-FD1R8KF is based on Faraday’s law of induction. This law states that a changing magnetic field is capable of inducing an electromotive force in a coil of wire or another nearby conductor. When an alternating current is applied to the ELJ-FD1R8KF, a changing magnetic field is generated that induces a voltage in the device. The amount of induced voltage is proportional to the rate of change of the current passing through the device. This induced voltage is then used to control the current that passes through the device.

The ELJ-FD1R8KF is a fixed inductor that is suitable for many applications, including power supplies, DC-to-AC inverters, filters, matching networks, and RF circuits. It features a high inductance value, low DCR, and exceptional high-frequency performance. The ELJ-FD1R8KF operates on the principle of Faraday’s law of induction, where an induced voltage is used to control the current that passes through the device. This inductor is capable of handling a peak current of up to 8A and has a maximum temperature rating of 125°C. It offers excellent field uniformity and is compatible with ROHS and WEEE compliant requirements.
