貼片疊層磁珠 EMI抑製器 積層大電流磁珠(TRMA)
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，抑製各種形式電磁波干擾，已成為設計工程師當務之急。德銘特片式 EMI 抑製器 TRMA 系列，採用積層鐵氧體磁珠（濾波電感器）是抑製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 抑製也要求縮小尺寸和採用表面安裝技術。德銘特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。
德銘特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。德銘特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，及需要多條線抑製噪聲要求應用。為提高貼裝效率，減小線路板上占用面積，亦可採用德銘特磁珠排產品，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。
鐵氧體抑製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製元件，就可以濾除高頻干擾。鐵氧體磁環或磁珠專用於抑製信號線、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沖干擾的能力。德銘特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、無鉛焊接對技術。
