"Somaloy(R)" is a soft magnetic material made of pure iron powder with an insulating coating, developed by our company ahead of the world. [Main Needs for Automotive Reactors] - Low cost - Low loss - Miniaturization [Features and Benefits of Somaloy] - Each particle of pure iron base powder is coated with an insulating layer, significantly reducing eddy current loss in the high-frequency range. - Being based on pure iron, it achieves high compressibility and easy handling, resulting in improved manufacturing efficiency. [Suitable Application Examples] - Boost reactors for DC/DC converters There is a proven track record of mass production of automotive boost reactors using "Somaloy(R)"! ★ We are currently offering the "Somaloy(R)" catalog without exception! ★ If you have any questions, please feel free to contact us♪
basic information
【Grade】 Covers from below 100Hz to 100kHz. 【Benefits of Utilizing 'Somaloy(R)'】 ■ Significant contribution to reducing iron loss, which is essential for miniaturization and high-frequency applications. 1) Hysteresis Loss Enables grade selection for applications such as low-cost grades and low hysteresis loss grades! 2) Eddy Current Loss It is possible to reduce eddy current loss, which increases with the square of frequency! Contributes to achieving low loss even in frequency ranges that were previously unattainable. ■ Contributes to the development of compact and lightweight reactors through high-frequency applications! 1) Insulating coatings applied to pure iron-based powder achieve high permeability with high compressibility. 2) Insulating coatings on each particle significantly reduce eddy current loss, especially in the high-frequency range.
