  安规Y电容是安规电容系列,安规电容是指用于这样的场合,即电容器失效后,不会导致电击,不危及人身安 全. 它包括了X电容和Y电容。 x电容是跨接在电力线两线(L-N)之间的电容, 一般选用金属薄膜电容;Y电容是分别跨接在电力线两线和地之间(L-E,N-E) 的电容,一般是成对出现。基于漏电流的限制,Y电容值不能太大,一般X电容是 uF级,Y电容是nF级。X电容抑制差模干扰,Y电容抑制共模干扰。安规Y电容又分Y1电容及Y2电容。
  脚距是指电容产品径向引出的两根银色引脚之间的距离,用于安装在线路板上。市场上98%的安规电容引脚材质都是镀锡铜包钢线,也就是大家常说的CP线。
  安规Y电容脚距分别可以做到7.5mm;9.5mm及10mm。Y1电容常规脚距是10mm,Y2电容常规脚距是7.5mm。脚距可按客人要求订制,有时会遇上客人要求安规Y电容脚距要做5mm,这不是国际标准,非常危险 。安规Y电容是高电压产品, 电压高, PCB板上电子元件多;电流电压过大;脚距小会容易引起打火,有安全隐患。
