村田鐵氧體磁珠
村田磁珠的特性與應(yīng)用
基本特性
村田磁珠是一種片狀鐵氧體磁珠,屬于EMI靜噪元件,也稱(chēng)為靜噪濾波器。它的學(xué)名叫片狀鐵氧體磁珠,功效等效于電阻和電感串聯(lián)在電路中,能夠在高頻通過(guò)時(shí)表現(xiàn)出阻性,從而發(fā)揮過(guò)濾高頻的濾波器作用12。
村田磁珠的主要原料是鐵氧體,通常由鐵鎂合金或鐵鎳合金制成,外表呈灰黑色。在電路中,高頻信號(hào)通過(guò)鐵氧體材料時(shí)會(huì)大量消耗高頻信號(hào),使得磁珠在電路中起著阻高頻通低頻的作用。具體來(lái)說(shuō),村田磁珠具有以下特性:
高頻損耗大:在高頻情況下,磁珠會(huì)消耗大量的能量,從而減少高頻噪聲。
導(dǎo)磁率高:具有很高的導(dǎo)磁率,使得電感的線(xiàn)圈繞組之間在高頻高阻的情況下產(chǎn)生的電容最小。
阻抗特性:在低頻時(shí)幾乎無(wú)阻抗,但在高頻時(shí)會(huì)產(chǎn)生較大的衰減,高頻電流在其中以熱量形式散發(fā)12。
應(yīng)用領(lǐng)域
村田磁珠廣泛應(yīng)用于各種電子設(shè)備中,特別是在以下領(lǐng)域:
通訊設(shè)備:用于抑制通訊設(shè)備中的高頻噪聲。
數(shù)字電視和計(jì)算機(jī):在數(shù)字電路中,由于脈沖信號(hào)含有頻率很高的高次諧波,磁珠能有效濾除這些高頻噪聲。
電源電路:用于電源電路中濾除高頻噪聲,適用于直流和交流輸出。
信號(hào)電纜:用于信號(hào)電纜的噪聲濾除,減少信號(hào)傳輸中的干擾12。
命名規(guī)則和參數(shù)
村田磁珠的命名規(guī)則通常包括型號(hào)和后綴,例如BLM18AG331SN1D。主要的參數(shù)包括:
直流電阻(DC Resistance):直流電流通過(guò)磁珠時(shí)的電阻值。
額定電流(Rated Current):磁珠正常工作時(shí)的最大允許電流。
阻抗(Impedance):在特定頻率下的阻抗值,通常以100MHz為標(biāo)準(zhǔn)。
阻抗-頻率特性:描述阻抗值隨頻率變化的曲線(xiàn)。
電阻-頻率特性和感抗-頻率特性:分別描述電阻和感抗隨頻率變化的曲線(xiàn)2。
結(jié)論
綜上所述,村田磁珠因其高效的高頻濾波性能和廣泛的應(yīng)用領(lǐng)域,在電子設(shè)備中發(fā)揮著重要作用。
