M0820-18K Working Principle

An inductor is an electronic component that stores energy in the form of a magnetic field. The inductance of the inductor is measured in henrys, and the higher the value of the inductance, the greater the amount of energy stored. The M0820-18K uses an iron-dust core to provide high inductance values; the core material has very low core losses and a high saturation current. This makes it suitable for use in power circuits that require high frequencies like boost and buck converters, and circuits that require high current ratings.

The inductor is designed to function as a DC-to-DC converter, meaning that it can convert a variable DC voltage to an increasing/decreasing voltage. The design of the M0820-18K also serves to improve its power efficiency. This improved efficiency means that the inductor can handle higher current ratings and still maintain a high power efficiency.

Conclusion

The M0820-18K fixed inductor is an excellent choice for circuit designs that require high efficiency and peak current ratings. This SMD power inductor module can be used in automotive, medical, communication and consumer electronics applications. Its efficient design and high inductance make it an excellent choice for high-power, high-frequency applications such as boost and buck converters. Finally, its low core losses and high saturation current make it an excellent choice for designers looking to maximize power efficiency.
