Abstract: The invention relates to a planar inductive component (11) comprising at least a first and a second concentric inductor, which include a first and a second spiral pattern (12A, 12B), respectively. Both spiral patterns have a first end point (13A, 13B) and a second end point (14A, 14B), are electrically interconnected, interlaced, and interrupted at the outer side, and provided with two contacts (16A, 16B) on one side of the opening (15A, 15B) and two contacts (17A, 17B) on the other side of the opening (15A, 15B). By interconnecting the first two contacts (16A, 16B) and the second two contacts (17A, 17B), respectively, both spiral patterns are connected in parallel. The spiral patterns (12A, 12B), which are magnetically coupled, have identical electrical and magnetic properties. This leads to a reduction of eddy current losses at high frequencies. This results in a planar inductive component (11) which is suitable for high-frequency operation with a high maximum quality factor Q. The invention also relates to a planar transformer comprising two planar inductive components according to the invention. The first planar inductive component serves as the first winding of the planar transformer; the second planar inductive component serves as the second winding of the planar transformer. As a result of the above-mentioned reduction in eddy current losses at high frequencies, the planar transformer can suitable be used for high-frequency operation.
