Power Inductor TOROID Coils with closed magnetic circuit for lowest EMI. TOROID coils are electronic components with the high performers among inductors, typically consisting of a circular ring-shaped magnetic core of iron powder, ferrite, or other material around which wire is coiled to make an inductor. TOROID inductors with a round core cross section are better performers than TOROID inductors with a rectangular cross section.
TOROID coils introduces advanced materials of iron core and special-purpose resins to produce the greatest inductance, high current, Lowest EMI, and Low cost.
G-CHEN will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
