Shanxi Leimai Electronic Technology Co., Ltd

Leimai’s Fe-based nanocrystalline cores are optimized for use in high-efficiency common mode chokes, providing superior electromagnetic interference (EMI) suppression across a broad spectrum. Their excellent permeability and low core loss make them ideal for modern switching power systems.
Compared to conventional ferrite materials, Leimai’s nanocrystalline cores deliver higher inductance with fewer winding turns, compact structure, better thermal performance, and reduced copper loss, offering a cost-effective and energy-efficient solution.
