FairRite原装进口磁芯磁环磁柱磁珠全系
将整束电缆穿过一个铁氧体磁环就构成了一个共模扼流圈，根据需要，也可以将电缆在磁环上面绕几匝。匝数越多，对频率较低的干扰抑制效果越好，而对频率较高的噪声抑制作用较弱。在实际工程中，要根据干扰电流的频率特点来调整磁环的匝数。通常当干扰信号的频带较宽时，可在电缆上套两个磁环，每个磁环绕不同的匝数，这样可以同时抑制高频干扰和低频干扰。从共模扼流圈作用的机理上看，其阻抗越大，对干扰抑制效果越明显。而共模扼流圈的阻抗来自共模电感Lcm=jwLcm，从公式中不难看出，对于一定频率的噪声，磁环的电感越大越好。但实际情况并非如此，因为实际的磁环上还有寄生电容，它的存在方式是与电感并联。当遇到高频干扰信号时，电容的容抗较小，将磁环的电感短路，从而使共模扼流圈失去作用
