FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. Inductor core is made of a compressed soft magnetic powder material and comprises a base core portion having a first surface and an opposite second surface; an inner core portion extending from first surface in a direction transverse to first surface; an outer core portion extending, in direction transverse to first surface, from first surface to an end surface of outer core portion. Outer core portion at least partly surrounding inner core portion, thereby forming a space around inner core portion for accommodating a winding. First surface comprises a recess for accommodating a connection portion of winding, said recess extending at least a part of a distance between inner core portion and outer core portion. Outer core portion has a slit extending from said end surface towards recess. Second surface comprises a first protrusion oppositely arranged to recess.

EFFECT: technical result consists in improvement of efficiency.
