磁珠的作用在成品电路板上,我们会看到一些导线或元件的引脚上套有黑色的小磁环,这就是本文要介绍的磁珠。磁珠的全称为铁氧体磁珠滤波器(另有一种是非晶合金磁性材料制作的磁珠),是一种抗干扰元件,滤除高频噪声效果显著。
贴片磁珠是电感、线圈类的东西,产品广泛应用于:PDA、ISDN、ADSL、MP3、CD、DVD、手机、电脑、电视机、数码相机、摄像头、 收录机、对讲机、EL 背光驱动、开关电源、遥控玩具、传真机、激光打印机及电子钟表等通讯和消费类电子领域。
贴片磁珠是由铁氧体材料和导体线圈组成的叠层型独石结构。
由于是在高温下烧结而成,因而致密性好、可靠性高。
两端的电极由银/镍/焊锡三层构成,可满足再流焊和波峰焊的要求。
磁珠是EMC设计中常使用的元件,在EMC对策中占重要位置.
铁氧体材料的特点是高频损耗非常大,具有很高的导磁率,使电感的线圈绕组之间在高频高阻的情况下产生的电容最校当磁珠中有电流穿过时,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的衰减。对于抑制电磁干扰用的铁氧体,最重要的性能参数为磁导率μ和饱和磁通密度Bs。它的等效电路为一个电感和一个电阻串联,两个元件的值都与磁珠的长度成比例。当导线穿过这种铁氧体磁芯时,所构成的电感阻抗是随着频率的升高而增加。高频电流在其中以热量形式散发。
在低频段,阻抗由电感的感抗构成。低频时R很小,磁芯的磁导率较高,因此电感量较大,L起主要作用,电磁干扰被反射而受到抑制,并且这时磁芯的损耗较小.整个器件是一个低损耗,高Q特性的电感。这种电感容易造成谐振.因此在低频段有时可能出现使用铁氧体磁珠后,干扰增强的现象。
在高频段,阻抗由电阻成分构成,随着频率升高,磁芯的磁导率降低,导致电感的电感量减小,感抗成分减校这时磁芯的损耗增加,电阻成分增加,导致总的阻抗增加。当高频信号通过铁氧体时,电磁干扰被吸收并转换成热能的形式耗散掉。
铁氧体磁珠广泛应用于印制电路板,如在印制板的电源线入口端套上磁珠(较大的磁环),就可以滤除高频干扰。铁氧体磁环或磁珠专用于抑制信号线、电源线上的高频干扰和尖峰干扰,它也具有吸收静电放电脉冲干扰的能力。
电感是储能元件,而磁珠是能量转换(消耗)器件。电感多用于电源滤波回路,侧重于抑制传导性干扰;磁珠多用于信号回路,主要用于EMI(电磁兼容)方面。磁珠用来吸收超高频信号,例如在一些RF电路、PLL、振荡电路、含超高频存储器电路等,都需要在电源输入部分加磁珠。
磁珠的单位是欧姆,是按照它在某一频率下产生的阻抗来标称的。磁珠的数据参数表(DATASHEET)上,一般会提供频率和阻抗的特性曲线图,常以100MHz为标准,比如600R@100MHz,意思就是在100MHz频率时磁珠的阻抗相当于600欧姆。
例如某磁珠参数为120Ω,25%,3A,1206,是指在频率1OOMHz时,阻抗值为1200,允许误差是:±25%,允许穿过的标称最大电流为3A;1206是外形尺寸,EIAl206(英制:英寸)等同于JIS/IEC3216(国际单位制:毫米),即长3.2mm、宽1.6mm。磁环和磁珠对高频成分起吸收作用,也称为吸收滤波器。
