However, since it is a through-disk type, in order to increase the acquired capacitance, it is necessary to increase the diameter of the ceramic body 52 and the area of the electrodes 53 and 54.
For this reason, the area occupied by the magnetic capacitor 5 on the grounding plate 4 becomes large, and when increasing the number of connector pins 2 to achieve multipolarization, the size of the magnetic capacitor 5 becomes an obstacle and the distance d 1 must be reduced. It becomes impossible to reduce the size below the limit, making multipolarization and miniaturization difficult.

Cracks etc. are likely to occur, reducing reliability.
(C) ノイズフイルタ要素が磁器コンデンサ５だけ

に対応することができるのである。<Function> Since the noise filter element includes a cylindrical ceramic capacitor having an inner circumferential electrode and an outer circumferential electrode which are independent of each other on the inner circumferential surface and the outer circumferential surface, when increasing the number of connector pins to make the connector pins multipolar, While reducing the outer diameter of the capacitor to reduce the area it occupies on the ground plate, it is possible to compensate for the decrease in acquired capacity due to the smaller diameter by increasing the axial length. That is, by using a cylindrical ceramic capacitor, the acquired capacitance can be increased without increasing the occupied area, and it is possible to respond to miniaturization and multipolarization.

供できる。(e) The magnetic material is loosely inserted into the inner diameter of the magnetic capacitor so that there is a gap between the outer circumferential surface and the inner circumferential surface of the magnetic capacitor, so there is no axial misalignment between the magnetic capacitor and the connector pin. It is possible to provide a connector that can prevent cracks and damage to magnetic bodies and ceramic capacitors even if such occurrence occurs.
