貼片電感作為(wei)一種常用(yong)電(dian)子器，在很(hen)多電(dian)子產品中都有(you)(you)著不可(ke)替代的作用(yong)。關(guan)于貼(tie)片(pian)電(dian)感(gan)的相關(guan)知(zhi)識，最近小編也是一直在給大(da)家(jia)做內(nei)容分(fen)享。本篇我們將繼續探討(tao)有(you)(you)關(guan)貼(tie)片(pian)電(dian)感(gan)的相關(guan)知(zhi)識。你知(zhi)道貼(tie)片(pian)電(dian)感(gan)的主要參數有(you)(you)哪些(xie)？

貼片(pian)電感參(can)(can)數其(qi)實有很多，小編在這里就不將貼片(pian)電感的(de)所有參(can)(can)數一一展開(kai)敘述(shu)，只挑(tiao)選(xuan)其(qi)中一些最為核心的(de)技術參(can)(can)數給(gei)大(da)家做一個簡單的(de)說明：

1、電感量（L）
電(dian)(dian)(dian)(dian)感(gan)(gan)量（L）我(wo)們(men)也稱為(wei)自感(gan)(gan)系數，用是(shi)來表(biao)示電(dian)(dian)(dian)(dian)感(gan)(gan)元(yuan)器件自感(gan)(gan)應(ying)能(neng)力(li)的(de)(de)(de)(de)(de)(de)一種物理量。當(dang)通(tong)過某(mou)一面(mian)(mian)面(mian)(mian)積的(de)(de)(de)(de)(de)(de)磁(ci)力(li)線(xian)(xian)數發生變(bian)化(hua)(hua)(hua)時(shi)，線(xian)(xian)圈(quan)(quan)中便會(hui)產(chan)(chan)生電(dian)(dian)(dian)(dian)勢(shi)(shi)，這就是(shi)我(wo)們(men)說的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)磁(ci)感(gan)(gan)應(ying)現象。而產(chan)(chan)生的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)勢(shi)(shi)則稱之為(wei)感(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)勢(shi)(shi)，電(dian)(dian)(dian)(dian)勢(shi)(shi)大小正比于磁(ci)通(tong)變(bian)化(hua)(hua)(hua)的(de)(de)(de)(de)(de)(de)速度和(he)線(xian)(xian)圈(quan)(quan)匝數。當(dang)線(xian)(xian)圈(quan)(quan)總童工變(bian)化(hua)(hua)(hua)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流時(shi)，線(xian)(xian)圈(quan)(quan)產(chan)(chan)生的(de)(de)(de)(de)(de)(de)磁(ci)通(tong)也月號變(bian)化(hua)(hua)(hua)，磁(ci)通(tong)掠過線(xian)(xian)圈(quan)(quan)，線(xian)(xian)圈(quan)(quan)兩端便會(hui)產(chan)(chan)生感(gan)(gan)應(ying)電(dian)(dian)(dian)(dian)勢(shi)(shi)，這就是(shi)自感(gan)(gan)性現象。自感(gan)(gan)電(dian)(dian)(dian)(dian)勢(shi)(shi)的(de)(de)(de)(de)(de)(de)方向總是(shi)阻止電(dian)(dian)(dian)(dian)流變(bian)化(hua)(hua)(hua)的(de)(de)(de)(de)(de)(de)，猶如線(xian)(xian)圈(quan)(quan)具(ju)有(you)慣性，這種電(dian)(dian)(dian)(dian)磁(ci)慣性的(de)(de)(de)(de)(de)(de)大小就用電(dian)(dian)(dian)(dian)感(gan)(gan)量L來表(biao)示。

2、感抗（XL）
感抗是用來表示當電感線圈的自感電勢在阻止線圈中電流變化時，所產生的阻力大小的。
3、品(pin)質因數Q

這是一個用來表示電感線圈品質的參數，我們稱之為Q值或者優值。線圈在一定頻率的交流電壓下工作時，其感抗XL和等效損耗電阻之比即為Q值，線圈的感抗越大，損耗電阻越小，其Q值就越高。
4、直流電阻
指的就是電感線圈自身的直流電阻。
5、額定電流
 通(tong)常(chang)是(shi)指允許長時間通(tong)過(guo)電(dian)(dian)(dian)感元件(jian)的(de)直流(liu)(liu)電(dian)(dian)(dian)流(liu)(liu)值。在(zai)選(xuan)用電(dian)(dian)(dian)感元件(jian)時，若(ruo)電(dian)(dian)(dian)路流(liu)(liu)過(guo)電(dian)(dian)(dian)流(liu)(liu)大(da)于額定(ding)電(dian)(dian)(dian)流(liu)(liu)值，就需改用額定(ding)電(dian)(dian)(dian)流(liu)(liu)符合(he)要求的(de)其他型號(hao)電(dian)(dian)(dian)感器。

以上就是(shi)貼(tie)片電(dian)感的主要技(ji)術(shu)參(can)數(shu)，我(wo)們在(zai)幫助客戶(hu)做電(dian)感選型時基(ji)本(ben)上也是(shi)圍繞這些主要的技(ji)術(shu)參(can)數(shu)展開(kai)的。
