作為比較常用同時也是市場需求最大的一類電感，覆蓋在我們生活的方方面面，包括射頻無線通訊，信息技術設備，雷達檢波器，汽車，蜂窩電話，尋呼機，音頻設備，移動設備，無線遙控系統以及低壓供電模塊等等。貼片電感是三大主(zhu)要被動電(dian)(dian)子元器件之一，種類多、應(ying)用(yong)廣(guang)，是電(dian)(dian)感(gan)元件領域重(zhong)點開發的(de)產品(pin)(pin)。的(de)應(ying)用(yong)廣(guang)泛，幾(ji)乎在(zai)所有(you)的(de)電(dian)(dian)子產品(pin)(pin)的(de)前后端電(dian)(dian)路中(zhong)，都會有(you)貼片(pian)電(dian)(dian)感(gan)的(de)應(ying)用(yong)，貼片(pian)電(dian)(dian)感(gan)主(zhu)要起到濾波、振蕩、延(yan)遲、陷波等作用(yong)，還有(you)篩(shai)選信號、過濾噪聲、穩定電(dian)(dian)流及抑制電(dian)(dian)磁波干擾等作用(yong)。

然而很多小伙伴不知道的(de)是，貼片(pian)電感其實還有自感和互感之分，今天(tian)小編(bian)就(jiu)為大家來(lai)詳細(xi)解(jie)析一(yi)下二(er)者的(de)區別：

其(qi)實分為自(zi)感(gan)(gan)(gan)器和(he)互(hu)(hu)(hu)感(gan)(gan)(gan)器，當(dang)線(xian)(xian)(xian)(xian)圈(quan)(quan)中(zhong)有電流同(tong)時(shi)(shi)(shi)時(shi)(shi)(shi)，線(xian)(xian)(xian)(xian)圈(quan)(quan)的(de)周圍(wei)就(jiu)會(hui)產生(sheng)磁(ci)場。當(dang)線(xian)(xian)(xian)(xian)圈(quan)(quan)中(zhong)電流發(fa)生(sheng)變化(hua)時(shi)(shi)(shi)，其(qi)周圍(wei)的(de)磁(ci)場也會(hui)相(xiang)(xiang)對應的(de)變化(hua)，變化(hua)的(de)磁(ci)場可(ke)是線(xian)(xian)(xian)(xian)圈(quan)(quan)自(zi)身產生(sheng)感(gan)(gan)(gan)應電動(dong)勢，這(zhe)種情(qing)況是自(zi)感(gan)(gan)(gan)。兩個貼片(pian)(pian)(pian)(pian)電感(gan)(gan)(gan)線(xian)(xian)(xian)(xian)圈(quan)(quan)相(xiang)(xiang)互(hu)(hu)(hu)靠近時(shi)(shi)(shi)，一盒貼片(pian)(pian)(pian)(pian)電感(gan)(gan)(gan)線(xian)(xian)(xian)(xian)圈(quan)(quan)的(de)磁(ci)場發(fa)生(sheng)變化(hua)，將(jiang)會(hui)影響另一個貼片(pian)(pian)(pian)(pian)電感(gan)(gan)(gan)線(xian)(xian)(xian)(xian)圈(quan)(quan)，這(zhe)種現象就(jiu)是互(hu)(hu)(hu)感(gan)(gan)(gan)，互(hu)(hu)(hu)感(gan)(gan)(gan)的(de)大(da)小(xiao)一般(ban)取決于貼片(pian)(pian)(pian)(pian)電感(gan)(gan)(gan)線(xian)(xian)(xian)(xian)圈(quan)(quan)的(de)自(zi)感(gan)(gan)(gan)與兩個貼片(pian)(pian)(pian)(pian)電感(gan)(gan)(gan)線(xian)(xian)(xian)(xian)圈(quan)(quan)耦(ou)合的(de)程度 ，互(hu)(hu)(hu)感(gan)(gan)(gan)器就(jiu)是由這(zhe)種原理制(zhi)作而成的(de)。
