Common mode inductor nanocrystalline magnetic cores are the core components of electromagnetic elements based on nanocrystalline soft magnetic materials. Nanocrystalline materials are formed by annealing and crystallization amorphous alloys. They possess characteristics such as high magnetic permeability (up to 10^5 grades), low coercive force, wide frequency response (applicable range DC-100 MHZ), and excellent temperature stability (stable performance from -55℃ to 130℃). When used as a common mode inductor, it can efficiently suppress high-frequency common mode interference signals in the circuit. With its high saturation magnetic induction intensity (about 1.2T) and low loss characteristics, it achieves miniaturization design while enhancing anti-interference efficiency. It is particularly suitable for high-frequency and integrated scenarios such as new energy vehicles, 5G communication equipment, and server power supplies. Provide high-performance magnetic core solutions for electromagnetic compatibility design.
