貼片電感其實也被稱為功率電(dian)感(gan)、大電(dian)流電(dian)感(gan)，它的特點(dian)總結起來(lai)就是(shi)具(ju)有小(xiao)型化、高品質、高能(neng)量存儲以及低電(dian)阻的特點(dian)。因此(ci)貼(tie)片電(dian)感(gan)的未來(lai)發展趨勢可(ke)以說非(fei)常好。本篇我(wo)們還(huan)是(shi)來(lai)探討一下貼(tie)片電(dian)感(gan)方面(mian)的小(xiao)知識，今天我(wo)們來(lai)聊聊貼(tie)片電(dian)感(gan)電(dian)流的問(wen)題。

有(you)很多在問現在的貼(tie)(tie)(tie)片(pian)(pian)功(gong)率電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)的電(dian)(dian)(dian)(dian)流(liu)(liu)最大(da)是(shi)多少的？貼(tie)(tie)(tie)片(pian)(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)的電(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)不(bu)是(shi)越(yue)大(da)越(yue)好？針(zhen)對(dui)貼(tie)(tie)(tie)片(pian)(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)電(dian)(dian)(dian)(dian)流(liu)(liu)是(shi)不(bu)是(shi)越(yue)大(da)越(yue)好這個(ge)問題呢，我(wo)們有(you)句俗話叫：物極必反！貼(tie)(tie)(tie)片(pian)(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)的電(dian)(dian)(dian)(dian)流(liu)(liu)肯(ken)定不(bu)是(shi)越(yue)大(da)越(yue)好的！貼(tie)(tie)(tie)片(pian)(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)作為(wei)電(dian)(dian)(dian)(dian)路板(ban)(ban)上的一個(ge)電(dian)(dian)(dian)(dian)子元器件(jian)，它的電(dian)(dian)(dian)(dian)流(liu)(liu)大(da)小肯(ken)定是(shi)要根據電(dian)(dian)(dian)(dian)路板(ban)(ban)實際需要而定，比(bi)如這個(ge)電(dian)(dian)(dian)(dian)路板(ban)(ban)只(zhi)能加載0.25A的電(dian)(dian)(dian)(dian)流(liu)(liu)，那么只(zhi)需要使用能夠(gou)滿足(zu)0.25A電(dian)(dian)(dian)(dian)流(liu)(liu)的貼(tie)(tie)(tie)片(pian)(pian)電(dian)(dian)(dian)(dian)感(gan)(gan)(gan)即可。

接(jie)下(xia)來再來看(kan)第一個問(wen)題(ti)：貼片(pian)(pian)功率電(dian)(dian)感電(dian)(dian)流(liu)最大是(shi)多(duo)(duo)少。目前(qian)各行業普遍使用的(de)(de)(de)貼片(pian)(pian)功率電(dian)(dian)感電(dian)(dian)流(liu)在1A以(yi)(yi)下(xia)的(de)(de)(de)居多(duo)(duo)。這個范圍內可以(yi)(yi)算是(shi)常(chang)規類型了(le)，1A以(yi)(yi)上就是(shi)電(dian)(dian)流(liu)比較(jiao)大的(de)(de)(de)了(le)。我(wo)們的(de)(de)(de)大功率貼片(pian)(pian)電(dian)(dian)感的(de)(de)(de)電(dian)(dian)流(liu)現在可以(yi)(yi)做到(dao)2A-3A。將電(dian)(dian)感的(de)(de)(de)電(dian)(dian)流(liu)從(cong)1A提升到(dao)3A，可不是(shi)一件非常(chang)簡單(dan)(dan)的(de)(de)(de)事(shi)情。我(wo)知道很多(duo)(duo)人可能會說只是(shi)1A增(zeng)加到(dao)3A，調整一下(xia)參數就行了(le)。但實際情況可不是(shi)大家認為的(de)(de)(de)那么簡單(dan)(dan)。

為什么(me)很多做常規電(dian)流的電(dian)感(gan)(gan)生(sheng)產(chan)廠家，你想讓他們給你提供2A或(huo)者3A的大電(dian)流電(dian)感(gan)(gan)他們會不(bu)愿意做。因為這(zhe)里(li)面涉及到的技(ji)術(shu)問題太多了，缺乏(fa)相應的技(ji)術(shu)配套是(shi)很難將電(dian)感(gan)(gan)電(dian)流從1A提升到2A甚至是(shi)3A的。關于貼片電(dian)感(gan)(gan)的電(dian)流大小受到哪些(xie)因素影響，我們下回再跟(gen)大家分(fen)享(xiang)！
