Magnetic Inductor Cores

Powder magnetic cores are manufactured by compressing insulating-coated metallic magnetic powder that have uniform voids distributed between the powder particles. This unique design results in minimal magnetic flux leakage and high insulation properties between the powder particles making them suitable for low-loss applications even in high-frequency environments.

Moreover, compared to conventional Ferrite materials, powder magnetic cores exhibit superior saturation characteristics allowing them to maintain high inductance even under high current conditions. This feature is advantageous for reducing the size of circuit devices.

Recently, with the increasing adoption of electric and hydrogen vehicles, as well as robots, UAM(Urban Air Mobility), smartphones, and other power-driven products, the utility of these components has expanded, positioning them as critical components in the industry.
