COMMON MODE NOISE FILTER AND MANUFACTURING METHOD THEREOF |
摘要 |
A common mode noise filter includes: a laminated body; and a first and second coil conductors that are formed inside the laminated body and face each other in a first direction, wherein the first coil conductor has a first surface facing the second coil conductor; the second coil conductor has a second surface facing the first surface; a distance between ends of the first and second surfaces in the first direction is longer than a distance between centers of the first and second surfaces in the first direction; the first and second surfaces have corners each formed into an arcuate shape in a cross section; and a relationship between a height h in the first direction and a width w in a second direction perpendicular to the first direction is h≧w in a cross section of each of the first and second coil conductors. |

1. A common mode noise filter comprising:
a laminated body; and a first coil conductor and a second coil conductor that are formed inside the laminated body and face each other in a first direction, wherein the first coil conductor has a first surface facing the second coil conductor, the second coil conductor has a second surface facing the first surface, a distance between an end of the first surface and an end of the second surface in the first direction is longer than a distance between a center of the first surface and a center of the second surface in the first direction, corners of each of the first surface and the second surface are formed into an arcuate shape in a cross section, and a relationship between a height h in the first direction and a width w in a second direction perpendicular to the first direction is h≧w in a cross section of each of the first and second coil conductors. |
