  • 贴片式EMI抑制器 射频叠层磁珠 积层磁珠

贴片式磁珠是一种能量消耗器件,用来在一些 RF 射频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。

贴片射频叠层磁珠的主要功能,是消除存在于传输线(PCB电路)结构中的 RF 射频噪声。RF 的射频能量是叠加在电平直流传输上的交流正弦波成分,直流成分是需要的"有用信号",而 RF 射频能量却是无用的干扰电磁波,沿着线路传输辐射(EMI)。要消除这些不需要的信号能量,常使用片式积层磁珠来扮演高频电阻的角色(衰减器、EMI抑制器),该器件允许直流信号通过,而滤除交流信号。然而,低频信号也会受到片式磁珠的影响。

德键片式叠层磁珠由软磁铁氧体材料组成,铁氧体是一种立方晶格结构的亚铁磁性材料,构成高体积电阻率的独石结构。这种材料的特点是高频损耗非常大,具有很高的导磁率,它可以使磁珠的电感于叠层之间,在高频高阻的情况下产生的电容最小。涡流损耗同铁氧体材料的电阻率成反比。涡流损耗随信号频率的平方成正比。

德键的片式叠层射频磁珠 (TRMB),具有小型化、和轻量化优点,在射频噪声频率范围内具有高阻抗,消除传输线中的电磁干扰。德键 (TRMB) 采用封闭磁路结构,可高密度安装并避免干扰,良好的焊锡性、及耐热性,大电流达 6A。能更好地消除信号的串绕。极好的磁屏蔽结构。 降低直流电阻,以免对有用信号产生过大的衰减。具有显著的高频特性和阻抗特性(更好的消除RF能量)。 在高频放大电路中消除寄生振荡。

正确的选择磁珠,通常必须注意以下几点:需要抑制或滤除信号的频率范围。主要的噪声源。需要多大的噪声衰减。使用的环境条件(如温度,直流电压,结构强度等)。电路和负载阻抗。PCB 板上放置磁珠的空间。选择在希望衰减噪声的频率范围内,在低频和直流下具有最大阻抗,信号衰减最小的磁珠型号。另须注意:片式磁珠在过大的直流电压下,或者外部磁场过大,或工作温升过高,磁珠的阻抗特性会受到影响。

德键电子积层贴片磁珠 (TRMB) 与 TDK 磁珠系列兼容,广泛使用在笔记型电脑、磁片驱动装置、喷墨印表机、硬碟磁碟机、影印机、显示监视器、游戏机、彩色电视、录放影机、光碟机、摄影机、数位相机、汽车电子产品、防干扰对策上。符合 RoHS 规范、Lead-Free 无铅环保要求、无铅焊接对技术。
