Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a noise countermeasure member which enables the achievement of a high impedance without leading to the upsizing of a magnetic material nor the increase in weight thereof.SOLUTION: A noise countermeasure member comprises: a magnetic material arranged in an annular form; at least one capacitor; and at least one conductor having a first portion connected to a first terminal of the capacitor, and a second portion connected to a second terminal of the capacitor. The at least one capacitor and the at least one conductor are disposed in such a loop position that they extend through both of outer and inner peripheral sides of the magnetic material. When a direction connecting between the first and second portions is defined as a first direction, and a direction orthogonal to both of the first direction and a thickness direction of the conductor is defined as a second direction, the at least one conductor is arranged to have a size of 10 mm or larger in the second direction.SELECTED DRAWING: Figure 1
【課題】磁性体の大型化及び重量増を招くことなく、高いインピーダンスを得ることが可能なノイズ対策部材を提供すること。【解決手段】ノイズ対策部材は、環状に構成される磁性体と、少なくとも一つのコンデンサと、第一部分がコンデンサの第一端子に接続されるとともに第二部分がコンデンサの第二端子に接続される少なくとも一つの導体とを有する。コンデンサ及び導体は、磁性体の外周側及び内周側の双方を経るようにループする位置に配設される。導体は、第一部分と第二部分との間を結ぶ方向を第一方向、第一方向及び導体の厚さ方向の双方に直交する方向を第二方向として、第二方向の寸法が10mm以上に構成されている。【選択図】図1 |
