一(yi)般(ban)電(dian)(dian)(dian)子線(xian)(xian)(xian)路(lu)中(zhong)的(de)(de)電(dian)(dian)(dian)感(gan)是空心(xin)線(xian)(xian)(xian)圈，或(huo)帶(dai)有磁(ci)芯(xin)的(de)(de)線(xian)(xian)(xian)圈，只(zhi)能(neng)通(tong)過較(jiao)小的(de)(de)電(dian)(dian)(dian)流(liu)，承受較(jiao)低的(de)(de)電(dian)(dian)(dian)壓;而功率電(dian)(dian)(dian)感(gan)也有空心(xin)線(xian)(xian)(xian)圈的(de)(de)，也有帶(dai)磁(ci)芯(xin)的(de)(de)，主要(yao)特點是用粗導線(xian)(xian)(xian)繞(rao)制，可承受數(shu)十(shi)安(an)，數(shu)百，數(shu)千，甚至于數(shu)萬安(an)。是分(fen)帶(dai)磁(ci)罩和不帶(dai)磁(ci)罩兩種，主要(yao)由磁(ci)芯(xin)和銅線(xian)(xian)(xian)組成。在電(dian)(dian)(dian)路(lu)中(zhong)主要(yao)起濾波和振蕩作用。

原理介紹：

電(dian)(dian)(dian)(dian)感(gan)(gan)是(shi)閉(bi)(bi)合回(hui)路(lu)(lu)的一種(zhong)屬(shu)(shu)性，即當通過(guo)閉(bi)(bi)合回(hui)路(lu)(lu)的電(dian)(dian)(dian)(dian)流(liu)改變(bian)時，會出現電(dian)(dian)(dian)(dian)動勢(shi)來抵抗電(dian)(dian)(dian)(dian)流(liu)的改變(bian)。這種(zhong)電(dian)(dian)(dian)(dian)感(gan)(gan)稱為(wei)自感(gan)(gan)，是(shi)閉(bi)(bi)合回(hui)路(lu)(lu)自己本身(shen)的屬(shu)(shu)性。假設一個(ge)(ge)閉(bi)(bi)合回(hui)路(lu)(lu)的電(dian)(dian)(dian)(dian)流(liu)改變(bian)，由于感(gan)(gan)應(ying)作用而(er)產(chan)生電(dian)(dian)(dian)(dian)動勢(shi)于另外一個(ge)(ge)閉(bi)(bi)合回(hui)路(lu)(lu)，這種(zhong)電(dian)(dian)(dian)(dian)感(gan)(gan)稱為(wei)互感(gan)(gan)。兩(liang)個(ge)(ge)電(dian)(dian)(dian)(dian)感(gan)(gan)線(xian)圈(quan)相互靠近時，一個(ge)(ge)電(dian)(dian)(dian)(dian)感(gan)(gan)線(xian)圈(quan)的磁場變(bian)化將(jiang)影響另一個(ge)(ge)電(dian)(dian)(dian)(dian)感(gan)(gan)線(xian)圈(quan)，這種(zhong)影響就是(shi)互感(gan)(gan)。互感(gan)(gan)的大小(xiao)取決于電(dian)(dian)(dian)(dian)感(gan)(gan)線(xian)圈(quan)的自感(gan)(gan)與兩(liang)個(ge)(ge)電(dian)(dian)(dian)(dian)感(gan)(gan)線(xian)圈(quan)耦合的程度，利用此原(yuan)理制成的元件叫做互感(gan)(gan)器。

貼片電感應用：

我們知道貼(tie)片(pian)(pian)電(dian)(dian)(dian)感(gan)(gan)(gan)廣泛適(shi)用于(yu)(yu)： 筆記(ji)本(ben)(ben)(ben)電(dian)(dian)(dian)腦(nao)，臺式電(dian)(dian)(dian)腦(nao)，服(fu)務器(qi)，顯卡,電(dian)(dian)(dian)視(shi)(shi)，智(zhi)能(neng)家(jia)居，LED 照明，汽車(che)產品(pin)，無線遙控系(xi)統(tong)以及低壓供電(dian)(dian)(dian)模塊等(deng)其(qi)(qi)它電(dian)(dian)(dian)子儀(yi)器(qi)設備。錄影機(ji)，OA 儀(yi)器(qi)，數碼相機(ji)，液(ye)晶電(dian)(dian)(dian)視(shi)(shi)，筆記(ji)本(ben)(ben)(ben)電(dian)(dian)(dian)腦(nao)，小型通信(xin)設備，DC/DC 轉換器(qi)。然貼(tie)片(pian)(pian)電(dian)(dian)(dian)感(gan)(gan)(gan)最大(da)的(de)(de)需求領域還是智(zhi)能(neng)終端市(shi)場上(shang)面，例如智(zhi)能(neng)手機(ji)和(he)(he)(he)平板電(dian)(dian)(dian)腦(nao)。像聯想(xiang)、華為(wei)和(he)(he)(he)中興等(deng)品(pin)牌對貼(tie)片(pian)(pian)電(dian)(dian)(dian)感(gan)(gan)(gan)的(de)(de)需求量越來越大(da)。主要(yao)(yao)是：貼(tie)片(pian)(pian)電(dian)(dian)(dian)感(gan)(gan)(gan)沒(mei)有引腳(jiao)，再也(ye)不需要(yao)(yao)寄生于(yu)(yu)電(dian)(dian)(dian)容了(le)，而且不需要(yao)(yao)人工插件(jian)，效率可以大(da)大(da)提(ti)升(sheng)，其(qi)(qi)所節約的(de)(de)時間(jian)成本(ben)(ben)(ben)和(he)(he)(he)人工成本(ben)(ben)(ben)要(yao)(yao)遠遠大(da)于(yu)(yu)插件(jian)電(dian)(dian)(dian)感(gan)(gan)(gan)。從而使產品(pin)的(de)(de)品(pin)質(zhi)大(da)大(da)提(ti)升(sheng)，同時貼(tie)片(pian)(pian)電(dian)(dian)(dian)感(gan)(gan)(gan)較(jiao)插件(jian)電(dian)(dian)(dian)感(gan)(gan)(gan)更加(jia)(jia)有性(xing)能(neng)是功率功能(neng)和(he)(he)(he)產品(pin)的(de)(de)穩定性(xing)，而插件(jian)電(dian)(dian)(dian)感(gan)(gan)(gan)在(zai)(zai)使用壽命(ming)遠遠不如貼(tie)片(pian)(pian)電(dian)(dian)(dian)感(gan)(gan)(gan)，貼(tie)片(pian)(pian)電(dian)(dian)(dian)感(gan)(gan)(gan)在(zai)(zai)磁(ci)(ci)屏(ping)蔽性(xing)功率方(fang)面也(ye)比(bi)較(jiao)有優勢，有利于(yu)(yu)增加(jia)(jia)其(qi)(qi)導磁(ci)(ci)率，磁(ci)(ci)性(xing)的(de)(de)強度和(he)(he)(he)產品(pin)的(de)(de)性(xing)能(neng)大(da)大(da)增加(jia)(jia)。目前汽車(che)領域的(de)(de)智(zhi)能(neng)化，以及物聯網方(fang)向，只能(neng)穿(chuan)戴設備，醫療器(qi)械(xie)行業等(deng)都有應用到(dao)。由此可以看來貼(tie)片(pian)(pian)電(dian)(dian)(dian)感(gan)(gan)(gan)應用還在(zai)(zai)不斷(duan)的(de)(de)壯大(da)著。
