| 发明名称 | Filter for removing noise | ||
| 摘要 | The present invention discloses a filter for removing noise, which includes: a lower magnetic body; primary and secondary patterns spirally provided on the lower magnetic body in parallel to each other; an insulating layer for covering the primary and secondary patterns; and an upper magnetic body provided on the insulating layer, wherein the primary and secondary patterns are formed to have a ratio of vertical thickness (T) to horizontal width (W) of 0.27≦T/W≦2.4. According to the present invention, it is possible to improve performance and capacity by implementing high common-mode impedance in the same frequency and reduce manufacturing costs by simplifying structures and processes. | ||

| 主权项 | 1. A filter for removing noise, comprising: a lower magnetic body; primary and secondary patterns spirally provided on the lower magnetic body in parallel to each other, the primary and secondary patterns being coplanar; an insulating layer to cover the primary and secondary patterns; and an upper magnetic body provided on the insulating layer, wherein the primary and secondary patterns are formed to have a ratio of vertical thickness (T) to horizontal width (W) of 0.27≦T/W≦2.4. | ||
