Fixed inductors, also known as coils, are components of electric circuits that are designed to impede the flow of the current and can also store and return energy, depending on the type of inductor. One of the most common types of discrete inductors is the LAN02KR270J, which is a surface-mountable, through-hole mixed-type inductor. This article will discuss the application field and the working principle of this inductor.

Application Field

The LAN02KR270J is specifically designed for portable communication devices, such as cell phones, digital cameras, and portable music players. This is due to its small size, low profile, and high reliability. The inductor also has two different varieties: the minimum self-resonant frequency (SRF) type and the high-Q type. The minimum SRF type is characterized by its low resonant frequency, wide range of inductance, and low DCR. The high-Q type is characterized by its high Q value, wide range of inductance, and low DCR.

Working Principle

The basic working principle of the LAN02KR270J inductor is very simple. When electric current passes through the inductor, it creates a magnetic field, which induces an opposing current in the inductor and thus reduces the total current that is flowing through the circuit. This is known as self-inductance, or the process of generating an opposing electromotive force. This opposes the original current and the change in current can be measured.

In order to improve the performance of the LAN02KR270J inductor, several special features are added. The core of the inductor is made with a special ferrite material, which greatly reduces the effects of inductive losses. Additionally, the coils of the inductor are wound with a special blend of enameled wire, which has superior electrical properties and helps to reduce losses even further. Lastly, the inductor is encapsulated in a special thermal setting resin, which aides in heat dissipation.

Conclusion

In conclusion, the LAN02KR270J is a very popular and powerful fixed inductor which is designed for use in portable communication devices. It has several special features which improve its performance, such as a special ferrite core, special enameled wire coils, and a special thermal setting resin encapsulation. This makes it an excellent choice for applications that require both high reliability and low losses.
