Title:
INDUCTOR
Document Type and Number:
Japanese Patent JP2022102391
Kind Code:
A
Abstract:
To provide an inductor which allows enhancement in insulation resistance between external electrodes and portions, in a winding part of a coil, having a potential significantly different from that of lead-out parts, thereby improving voltage withstanding capability between the winding part of the coil and the external electrodes.SOLUTION: An inductor 1 comprises: an element body 2 which has a magnetic part 6 containing magnetic powder and a coil 8 at least partially embedded in the magnetic part 6, and which has two principal surfaces 2a, 2b and lateral surfaces adjacent to the two principal surfaces 2a, 2b; and a pair of external electrodes 4A, 4B which is formed at least on one of the principal surfaces 2a, 2b of the element body, and which is connected to the coil 8. The coil 8 has: a winding part 10 which is formed by winding, on upper and lower two stages, a conductor wire having an insulation coating in such a manner that its both ends are located on the outermost circumference; and a pair of lead-out parts 16A, 16B which is led out from the outermost circumference of the upper stage 12 and the lower stage 14 so as to be connected to the external electrodes 4A, 4B. When viewed through from the principal surfaces 2a, 2b side of the element body, there are formed insulator parts 20 on the insulation coating on surfaces, of the winding part 10, which face the external electrodes 4A, 4B.SELECTED DRAWING: Figure 3
