Title:
COIL COMPONENT
Document Type and Number:
Japanese Patent JP2017126634
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a coil component in which an isolation voltage in a drawing part of a wire is improved.SOLUTION: A coil component comprises: a coil C2 which is wound to a core part 21, of which one end is connected to a terminal electrode E2, and of which the other end is connected to a terminal electrode E6; and a coil C4 which is wound to the coil part 21, of which one end is connected to a terminal electrode E3, and of which the other end is connected a terminal electrode E4. The coils C2 and C4 include: a winding part Ca regularly wound in the coil part 21; a first drawing part Cb positioned between the winding part Ca and a flange part 22; and a second drawing part Cc positioned between the coil part Ca and a flange part 23. The coils C2 and C4 intersect in the first drawing part Cb, and the coil C2 is constructed by two wires W3 and W4. Since an electric field intensity at a part of crossing the wires is softened, an isolation voltage in the drawing part is improved.SELECTED DRAWING: Figure 2
