Horizontal Ferrous Silicon Aluminum Toroidal Inductor

Horizontal Ferrous Silicon Aluminum Toroidal Inductor

Toroidal inductor toroidal coil, package form is plug-in inductor, winding form is single layer dense winding type, conductor nature is ferrite core, core shape is toroidal, operating frequency is medium frequency, mounting method is horizontal, skeleton material is magnetic core, quality factor Q is 45, inductance is 0.01-100 (mH), rated current is 0.10-10000 (mA), distributed capacitance is 0.08 ( F)

Toroidal coil, using iron powder core or manganese zinc and special resin for materials to produce large inductance, high current, anti-interference countermeasures, is one of the common power Inductors. Toroidal coil inductor, the ideal shape in inductor theory, uses closed magnetic circuit, few emi problems, makes full use of magnetic circuit, easy to calculate, bottom cost, almost all the theoretical benefits go to toroidal coil inductor. Mainly used in power supply, switching circuits, control rectifiers and thyristor control circuits, output chokes and emi/rfi chokes, other filters.

Toroidal cores not only have excellent magnetic properties, but also have many mechanical advantages: inter-piece pressure can be strictly controlled and can reach 95% of the same level, the use of impregnation technology allows the core to become a solid whole, in the winding and processing process does not change the image; because the toroidal core is very solid, reducing the impact of magnetostrictive forces, and thus reducing vibration and audio noise.
