技術規格

平面型磁性元件的出現為傳統磁性元件的設計增加靈活性和優勢。雖然可以看出幾何差異(主要是成品的總高度),但平面型幾何結構提供了數個設計優勢。 平面磁芯通常具有較大的中心磁芯腿橫截面積,這減少了實現所需磁化電感需求的導線匝數。平面磁性裝置成品使用印刷電路板 (PCB) 繞組、交錯螺旋繞組或環沖壓扁線或鍵片式繞組進行組裝。這些形式中的每一款都可以在裝置中產生線匝,幾乎不需要繞線筒或線圈架來繞線。

planar magnetic devices

由於扁平線或分層 PCB 跡線繞組和交錯繞組,這兩項元件物理佈局方面造就更高的電流能力、良好的散熱和低寄生漏電。由於較大的中心腿磁芯幾何形狀和磁芯材料的選擇,可實現低磁芯損耗。具有高效磁芯自屏蔽和繞組緊密耦合的平面磁設計,其緊湊特性也具有 EMI 優勢。

所有這些設計優勢使得具有良好導熱和散熱性能的低高度元件具備更高的體積功率密度、更低的損耗和更高的效率。
