贴片叠层磁珠 EMI抑制器 积层大电流磁珠(TRMA)
随着信息设备和移动通信网络的不断发展，空间电磁波干扰对电子设备和人体健康的影响越来越严重，保护电磁环境，抑制各种形式电磁波干扰，已成为设计工程师当务之急。德铭特片式 EMI 抑制器 TRMA 系列，采用积层铁氧体磁珠（滤波电感器）是抑制线路传导性电磁干扰的有效手段。
随着电子设备的小型化和薄型化，对 EMI 抑制也要求缩小尺寸和采用表面安装技术。德铭特已生产的品种有表面安装的片式磁珠、片式磁珠排、片式共模扼流圈、片式滤波器电感等。
德铭特片式磁珠有绕线型和积层型之分，绕线型磁珠的结构与穿心电感相似，但导线经过打弯后适合表面安装；积层型磁珠 TRMA 采用高级的磁性浆料与导电浆料交替印刷制成叠层体，在铁氧体层内部有直线状或线圈状的内导体。德铭特采用高磁导率材料的铁氧体材料，在高频时有大的损耗，可消耗和吸收干扰信号的能量，适合笔记本计算机输出线，及液晶显示器外围总线，及需要多条线抑制噪声要求应用。为提高贴装效率，减小线路板上占用面积，亦可采用德铭特磁珠排产品，包含有多个同样阻抗的磁珠。
磁珠（bead）通常匝数较少，是一种能量消耗器件，用来在一些 RF 电路中吸收高频信号，在对高频信号表现出高阻抗，将信号转化为热能，磁珠的主要原料为铁氧体。铁氧体是一种立方晶格结构的亚铁磁性材料。这种材料的特点是高频损耗非常大，具有很高的导磁率，它可以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小。
铁氧体抑制元件广泛应用于印制电路板、电源线和资料线上。如在印制板的电源线入口端加上铁氧体抑制元件，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。德铭特电子生产的大电流积层贴片磁珠采用封闭磁路结构，积层贴片磁珠可高密度安装并避免干扰，符合RoHS规范、Lead-Free无铅环保要求、无铅焊接对技术。
