Fixed inductors are passive components used for electrical purposes, such as producing alternating current and storing energy. The DC1390R-823K is a specific type of fixed inductor largely used for power applications, as it is designed to have high current capacity and low level of leakage. This article will discuss the application field and working principle of the DC1390R-823K.

The DC1390R-823K fixed inductors are applicable to a wide range of power applications. They previously found use in computer, communications, and consumer electronic products, and is suitable for DC/DC conversion and power supply applications that require high current ratings and low leakage. They are also used in primary-side power factor correction circuits, USB Type-C applications, and in radio-frequency identification (RFID) reader circuits, among other applications.

The DC1390R-823K\'s high current ratings and low leakage are mainly attributed to their core and winding design. The cores are made from MPP-206D10 material, a type of high-saturation material, in order to ensure resistances remain low and losses minimal. This material also allows for high inductance while keeping its size and weight low. In addition, the winding is designed to help reduce resistance and reduce energy losses during current transmission.

The DC1390R-823K\'s working principle relies on the principle of mutual induction. When current flows through the inductor\'s windings, a radial magnetic field is created that surrounds the core. This magnetic field will then induce a voltage in any neighbouring conducting material, which is known as the “self-inductance” of the inductor. The inductance is then determined by the ratio of the voltage induced to the rate of current change.

The voltage induced is also directly proportional to the number of turns in the inductor\'s winding. When the number of turns is increased, it will further enhance the self-inductance of the inductor, and vice-versa. Therefore, the DC1390R-823K’s high inductance is mainly attributed to its winding design, and the high current ratings and low leakage are attributed to its core and winding design.

The DC1390R-823K fixed inductor is designed to be highly efficient and reliable for use in a wide range of power applications. Its core and winding design ensures high inductance and resistance remain low, and its working principle relies on the principle of mutual induction to generate the voltage the inductor requires. Its various properties make it suitable for a variety of power applications, such as DC/DC conversion and power supply circuits.
