铁氧体磁珠 (Ferrite Bead) 是目前应用发展很快的一种抗干扰组件，廉价、易用，滤除高频噪声效果显着。 在电路中只要导线穿过它即可（普通电阻模样的，导线已穿过并胶合，也有表面贴装的形式，但很少见到卖的）。当导线中电流穿过时，铁氧体对低频电流几乎没有什么阻抗，而对较高频率的电流会产生较大衰减作用。高频电流在其中以热量形式散发，其等效电路为一个电感和一个电阻串联，两个组件的值都与磁珠的长度成比例。磁珠种类很多，制造商应提供技术指标说明，特别是磁珠的阻抗与频率关系的曲线。有的磁珠上有多个孔洞，用导线穿过可增加组件阻抗（穿过磁珠次数的平方），不过在高频时所增加的抑制噪声能力不可能如预期的多，而用多串联几个磁珠的办法会好些。[1] 铁氧体是磁性材料，会因通过电流过大而产生磁饱和，导磁率急剧下降。大电流滤波应采用结构上专门设计的磁珠，还要注意其散热措施。 0201JR 0201KRX7R9BB271 0402CS-10NXGLW 0402CS-10NXJBW 0402CS-10NXJLW 0402CS-11NXJLW 0402CS-12NXJBW 0402CS-12NXJLP 0402CS-12NXKBG
