貼片式磁珠是一種能量消耗器件,用來在一些 RF 射頻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。

貼片射頻疊層磁珠的主要功能,是消除存在於傳輸線(PCB電路)結構中的 RF 射頻噪聲。RF 的射頻能量是疊加在電平直流傳輸上的交流正弦波成分,直流成分是需要的"有用信號",而 RF 射頻能量卻是無用的干擾電磁波,沿著線路傳輸輻射(EMI)。要消除這些不需要的信號能量,常使用片式積層磁珠來扮演高頻電阻的角色(衰減器、EMI抑製器),該器件允許直流信號通過,而濾除交流信號。然而,低頻信號也會受到片式磁珠的影響。

德鍵片式疊層磁珠由軟磁鐵氧體材料組成,鐵氧體是一種立方晶格結構的亞鐵磁性材料,構成高體積電阻率的獨石結構。這種材料的特點是高頻損耗非常大,具有很高的導磁率,它可以使磁珠的電感於疊層之間,在高頻高阻的情況下產生的電容最小。渦流損耗同鐵氧體材料的電阻率成反比。渦流損耗隨信號頻率的平方成正比。

德鍵的片式疊層射頻磁珠 (TRMB),具有小型化、和輕量化優點,在射頻噪聲頻率範圍內具有高阻抗,消除傳輸線中的電磁干擾。德鍵 (TRMB) 採用封閉磁路結構,可高密度安裝並避免干擾,良好的焊錫性、及耐熱性,大電流達 6A。能更好地消除信號的串繞。極好的磁屏蔽結構。 降低直流電阻,以免對有用信號產生過大的衰減。具有顯著的高頻特性和阻抗特性(更好的消除RF能量)。 在高頻放大電路中消除寄生振蕩。

正確的選擇磁珠,通常必須注意以下幾點:需要抑制或濾除信號的頻率範圍。主要的噪聲源。需要多大的噪聲衰減。使用的環境條件(如溫度,直流電壓,結構強度等)。電路和負載阻抗。PCB 板上放置磁珠的空間。選擇在希望衰減噪聲的頻率範圍內,在低頻和直流下具有最大阻抗,信號衰減最小的磁珠型號。另須注意:片式磁珠在過大的直流電壓下,或者外部磁場過大,或工作溫升過高,磁珠的阻抗特性會受到影響。

德鍵電子積層貼片磁珠 (TRMB) 與 TDK 磁珠系列兼容,廣泛使用在筆記型電腦、磁片驅動裝置、噴墨印表機、硬碟磁碟機、影印機、顯示監視器、遊戲機、彩色電視、錄放影機、光碟機、攝影機、數位相機、汽車電子產品、防干擾對策上。符合 RoHS 規範、Lead-Free 無鉛環保要求、無鉛焊接對技術。
