隨著信息設備和移動通信網絡的不斷發展,空間電磁波干擾對電子設備和人體健康的影響越來越嚴重,保護電磁環境,抑制各種形式電磁波干擾,已成為設計工程師當務之急。德鍵片式 EMI 抑製器 TRMA 系列,採用積層鐵氧體磁珠(濾波電感器)是抑制線路傳導性電磁干擾的有效手段。

隨著電子設備的小型化和薄型化,對 EMI 抑制也要求縮小尺寸和採用表面安裝技術。德鍵已生產的品種有表面安裝的片式磁珠、片式磁珠排、片式共模扼流圈、片式濾波器電感等。

德鍵片式磁珠有繞線型和積層型之分,繞線型磁珠的結構與穿心電感相似,但導線經過打彎後適合表面安裝;積層型磁珠 TRMA 採用高級的磁性漿料與導電漿料交替印刷製成疊層體,在鐵氧體層內部有直線狀或線圈狀的內導體。德鍵採用高磁導率材料的鐵氧體材料,在高頻時有大的損耗,可消耗和吸收干擾信號的能量,適合筆記本計算機輸出線,及液晶顯示器外圍總線,及需要多條線抑制噪聲要求應用。為提高貼裝效率,減小線路板上佔用面積,亦可採用德鍵磁珠排產品,包含有多個同樣阻抗的磁珠。

磁珠(bead)通常匝數較少,是一種能量消耗器件,用來在一些 RF 電路中吸收高頻信號,在對高頻信號表現出高阻抗,將信號轉化為熱能,磁珠的主要原料為鐵氧體。鐵氧體是一種立方晶格結構的亞鐵磁性材料。這種材料的特點是高頻損耗非常大,具有很高的導磁率,它可以使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。

鐵氧體抑制元件廣泛應用於印製電路板、電源線和資料線上。如在印製板的電源線入口端加上鐵氧體抑制元件,就可以濾除高頻干擾。鐵氧體磁環或磁珠專用於抑制信號線、電源線上的高頻干擾和尖峰干擾,它也具有吸收靜電放電脈衝干擾的能力。德鍵電子生產的大電流積層貼片磁珠採用封閉磁路結構,積層貼片磁珠可高密度安裝並避免干擾,符合RoHS規範、Lead-Free無鉛環保要求、無鉛銲接對技術。
