Fixed inductors are electronic components that store energy in the form of a magnetic field when an electrical current is passed through them. The LAN02KR391J is a general-purpose, high-current fixed inductor that is mainly used in power supply systems of various electrical and electronic equipment. This inductor features high-Q performance, high-current capacity and very low ESR. It is widely used in switching power supplies, current mode DC/DC converters, and buck converters.

The LAN02KR391J has a cylindrical body made of ferrite material. It is rated with rated inductance of 0.47μH and a rated current of 3.50A. It has a tolerance of ±10%, an output resistance of 0.080Ω and a self-resonant frequency of 1MHz. The inductor has a rated voltage of 30VAC/50VDC and a working temperature range of -55°C～+125°C.

The working principle of the LAN02KR391J is very simple. When an alternating current is applied, it forms an alternating magnetic field that dissipates energy. This alternating magnetic field induces an AC voltage in the inductor coil, which stores energy in the form of a magnetic flux. When the current changes direction, the stored magnetic energy is released and an alternating current is generated. The current is converted into a steady voltage and then goes on to power the device.

The current-handling capacity of the LAN02KR391J is sufficient for most applications. It operates at a relatively high efficiency and has a very low DC resistance, which helps reduce heat generation. This makes it suitable for applications that require low noise and high efficiency operation. It is also used in various applications such as flyback converters, power line filters, and circuit stabilization.

The LAN02KR391J is meant for high current applications and is designed to withstand a wide range of temperatures. It has a good thermal stability and can handle high surge current. This makes it suitable for use in harsh operating conditions such as high-temperature environments and high-current applications. It is also very reliable and has a long service life.

The LAN02KR391J offers a wide range of benefits and is suitable for a variety of applications. It is ideal for high current applications that require low noise operation and high efficiency. It is also designed to be efficient and reliable and has a long service life. The inductor is also available in an easy to mount package and is a cost-effective solution for power applications.
