磁珠简介!磁珠命名规则及功能原理
磁珠简介!磁珠命名规则及功能原理
1.磁珠简介
村田（muRata）磁珠属于EMI静噪元件,也同属于静噪滤波器，学名叫片状铁氧体磁珠，功效等效于电阻和电感串联在电路中，阻值和电感值都由电路中频率变化而变化，在有高频通过时，表现出阻性，从而发挥出过滤高频的滤波器作用。
生产村田磁珠主要原料是铁氧体，主要成分是铁镁合金或铁镍合金，外表成灰黑色。
电路中的高频信号在通过铁氧体这种材料时会大量消耗高频信号，正是因为铁氧体的这种消耗高频的特性，使得磁珠在电路中起着阻高频通低频的作用。
2.磁珠命名规则
下图以型号BLM18AG331SN1D为例说明磁珠的命名规则
3.磁珠特性参数
（1）直流电阻DCResistance(mohm)：直流电流通过此磁珠时，此磁珠所呈现的电阻值。
（2）额定电流RatedCurrent(mA)：表示磁珠正常工作时的最大允许电流。
（3）阻抗[Z]@100MHz(ohm)：这里所指的是交流阻抗。
（4）阻抗-频率特性：描述阻抗值随频率变化的曲线。
（5）电阻-频率特性：描述电阻值随频率变化的曲线
（6）感抗-频率特性：描述感抗随频率变化的曲线
4.磁珠结构
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。
