FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in the manufacture of common-mode interference-suppressing chokes made on toroidal magnetic cores made of thin nanocrystalline and amorphous AMAG alloy tapes for installation in interference-suppressing filters. The technical result is an increase in the inductance coefficient and reduction of the weight and overall dimensions. Common-mode noise-suppressing chokes are made on toroidal magnetic conductors made of amorphous AMAG170 and nanocrystalline AMAG 200C alloys in the form of thin 18-20 micron tapes, the twisted magnetic tape is placed in a rigid protected container with rounded edges, over which the windings are wound with copper insulated wire, the container with the windings is placed in a plastic cylindrical container and prepared for pouring with a solidifying compound containing nanocrystalline and amorphous crushed fractions and ferromagnetic powders.
EFFECT: technical result is an increase in the inductance coefficient and reduction of the weight and overall dimensions.
