貼(tie)片(pian)功率電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)(gan)，此類貼(tie)片(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)(gan)又稱(cheng)為功率電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)(gan)，大電(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)(gan)。貼(tie)片(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)(gan)，是閉合回路的一種屬性。當(dang)貼(tie)片(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)(gan)的線(xian)圈(quan)通過電(dian)(dian)(dian)(dian)流后，貼(tie)片(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)(gan)在線(xian)圈(quan)中(zhong)形成磁場感(gan)(gan)(gan)(gan)應(ying)，磁場感(gan)(gan)(gan)(gan)應(ying)又會產(chan)生感(gan)(gan)(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)流來抵制通過線(xian)圈(quan)中(zhong)的電(dian)(dian)(dian)(dian)流。
電感(gan)價(jia)格的(de)(de)(de)(de)高低取決(jue)于電感(gan)的(de)(de)(de)(de)生(sheng)產成(cheng)(cheng)本(ben)有多少(shao)，決(jue)定(ding)電感(gan)成(cheng)(cheng)本(ben)的(de)(de)(de)(de)因素大概有以(yi)下五個方面，生(sheng)產材料成(cheng)(cheng)本(ben)、包括電感(gan)磁芯，骨架等構(gou)成(cheng)(cheng)電感(gan)的(de)(de)(de)(de)基本(ben)材料以(yi)及(ji)銅線(xian)的(de)(de)(de)(de)價(jia)格，另(ling)外(wai)還包括人工成(cheng)(cheng)本(ben)、技術成(cheng)(cheng)本(ben)、運輸成(cheng)(cheng)本(ben)以(yi)及(ji)服務…
電感一(yi)(yi)般由(you)骨(gu)架、繞(rao)組、屏蔽罩、封裝材(cai)料、磁(ci)心或鐵心組成(cheng)，共模電感作為(wei)電感器(qi)的一(yi)(yi)種，組成(cheng)也是如此(ci)，尤其是磁(ci)芯(xin)(xin)(xin)種類非常(chang)多，每種磁(ci)芯(xin)(xin)(xin)的所能(neng)承受的溫(wen)度、價格、以及適用(yong)的頻段等(deng)等(deng)都不相同，今(jin)天谷景電子(zi)重點講一(yi)(yi)下共模電感的磁(ci)芯(xin)(xin)(xin)應該如何選(xuan)擇。
