村田貼片疊層鐵氧體磁珠
村田磁珠的特性與應用
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,也稱為靜噪濾波器。它的學名叫片狀鐵氧體磁珠,功效等效于電阻和電感串聯在電路中,能夠在高頻通過時表現出阻性,從而發揮過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,高頻信號通過鐵氧體材料時會大量消耗高頻信號,使得磁珠在電路中起著阻高頻通低頻的作用。具體來說,村田磁珠具有以下特性:
高頻損耗大:在高頻情況下,磁珠會消耗大量的能量,從而減少高頻噪聲。
導磁率高:具有很高的導磁率,使得電感的線圈繞組之間在高頻高阻的情況下產生的電容最小。
阻抗特性:在低頻時幾乎無阻抗,但在高頻時會產生較大的衰減,高頻電流在其中以熱量形式散發12。
應用領域
村田磁珠廣泛應用于各種電子設備中,特別是在以下領域:
通訊設備:用于抑制通訊設備中的高頻噪聲。
數字電視和計算機:在數字電路中,由于脈沖信號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。
信號電纜:用于信號電纜的噪聲濾除,減少信號傳輸中的干擾12。
命名規則和參數
村田磁珠的命名規則通常包括型號和后綴,例如BLM18AG331SN1D。主要的參數包括:
直流電阻(DC Resistance):直流電流通過磁珠時的電阻值。
額定電流(Rated Current):磁珠正常工作時的最大允許電流。
阻抗(Impedance):在特定頻率下的阻抗值,通常以100MHz為標準。
阻抗-頻率特性:描述阻抗值隨頻率變化的曲線。
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2。
結論
綜上所述,村田磁珠因其高效的高頻濾波性能和廣泛的應用領域,在電子設備中發揮著重要作用。
