Fixed inductors are generally divided into three categories: cylindrical inductors, rod inductors, and film inductors. Among them, cylindrical inductors are more common and have the advantages of low cost and mature technology. DC1390-683K is a micro-sized cylindrical inductor of JiaLi Electronics. It is one of the most popular models in the series.

DC1390-683K has a diameter of 0.45 inches and a height of 0.30 inches. The device is designed to be used on a through-hole board and has eight pins. The inductance range is 0.83μH to 6.8μH. The maximum operating temperature is 125℃, and the DC current range is 2.4A to 11A. The inductance of DC1390-683K can be adjusted with a variety of different load currents. The rated current of the device is 10A.

The main application field of DC1390-683K is power management field. Slow-down inductors, which are used to limit inrush current, are a type of power management application for DC1390-683K. With a wide range of current ratings, the device can be used in a variety of power control circuits. In addition, the device can also be used in consumer electronics products, automotive applications, security systems, and other industries.

The basic working principle of DC1390-683K is that as the current passing through the coil increases, the inductance of the inductor increases accordingly. The increase of inductance is dependent on two factors. Firstly, with an increase in the current, the magnetic flux generated by the current increases, which in turn increases the inductance of the inductor. Secondly, the increase in current generates a self-induction voltage, which opposes the applied current, and also causes the inductance of the inductor to increase.

In summary, DC1390-683K is a cylindrical inductor with an operating temperature range of -40℃ to 125℃ and a DC current range of 2.4A to 11A. It is mainly used in power management, consumer electronics, automotive, security system, and other fields. The device works by increasing the magnetic flux with an increase in current, and by generating an opposing voltage thereby increasing the inductance of the inductor.
