装置和连接方法
摘要：
本发明涉及一种防止流过电源端子的噪声向电源泄漏的装置和连接方法。电源总线(2)的一端(r20)通过铁氧体磁环(3)与电源(Vc)连接。此时，在电源端子(P11、P21、P31、P41)上，噪声强度越大，电源端子(P11、P21、P31、P41)就与越靠近电源总线(2)的另一端(r201)的位置(r24、r23、r22、r21)连接。另外，接地端子(P12、P22、P32、P42)分别与接地连接，电容器(C1～C4)例如为旁路电容器或去耦电容器，分别连接在电源端子(P11、P21、P31、P41)与接地之间。
摘要（英）：

The present invention provides a device in which the noise flowing in power-supply terminals is prevented from leaking to a power supply and a connecting method. One end (r20) of a power-supply bus (2) is connected to a power supply (Vc) through a ferrite bead (3). The power-supply bus (2) is connected to power-supply terminals (P11, P21, P31, P41). The power-supply terminals (P11, P21, P31, P41) are connected at positions (r24, r23, r22, r21) in such a manner that a terminal with a higher intensity (a1 to a4) is connected closer to the other end (r201) of the power-supply bus (2). Ground terminals (P12, P22, P32, P42) are connected to ground. Capacitors (C1 to C4) are bypass capacitors or decoupling capacitors, for example, and connected between respective power-supply terminals (P11, P21, P31, P41) and ground.
