貼片功率電感是(shi)一種(zhong)應用廣泛的(de)(de)電(dian)感(gan)(gan)，大(da)(da)(da)家對貼片功(gong)率電(dian)感(gan)(gan)的(de)(de)選擇也有很多問(wen)題，比如(ru)它的(de)(de)尺(chi)寸(cun)。很多人問(wen)貼片功(gong)率電(dian)感(gan)(gan)的(de)(de)大(da)(da)(da)小是(shi)否越大(da)(da)(da)越好？還是(shi)尺(chi)寸(cun)越大(da)(da)(da)，相對電(dian)氣性能越好？貼片功(gong)率電(dian)感(gan)(gan)的(de)(de)封(feng)(feng)裝(zhuang)(zhuang)方式主要分(fen)為：四點封(feng)(feng)裝(zhuang)(zhuang)和全(quan)封(feng)(feng)裝(zhuang)(zhuang)兩種(zhong)封(feng)(feng)裝(zhuang)(zhuang)方式，而(er)封(feng)(feng)裝(zhuang)(zhuang)尺(chi)寸(cun)也是(shi)根據不同的(de)(de)封(feng)(feng)裝(zhuang)(zhuang)類型也有所(suo)不同，下(xia)面(mian)且小編(bian)為大(da)(da)(da)家來詳(xiang)解貼片功(gong)率電(dian)感(gan)(gan)封(feng)(feng)裝(zhuang)(zhuang)及尺(chi)寸(cun)。

貼片(pian)功(gong)(gong)率(lv)(lv)電(dian)(dian)(dian)(dian)(dian)感(gan)的(de)(de)尺寸(cun)也(ye)就是我們常說的(de)(de)封(feng)裝尺寸(cun)，它反(fan)映了貼片(pian)功(gong)(gong)率(lv)(lv)電(dian)(dian)(dian)(dian)(dian)感(gan)的(de)(de)物(wu)理(li)形狀。很多人認為貼片(pian)功(gong)(gong)率(lv)(lv)電(dian)(dian)(dian)(dian)(dian)感(gan)尺寸(cun)越(yue)大，各(ge)方面的(de)(de)電(dian)(dian)(dian)(dian)(dian)氣(qi)性(xing)能越(yue)好(hao)。其實(shi)并不(bu)是大家想的(de)(de)那樣(yang)。貼片(pian)功(gong)(gong)率(lv)(lv)電(dian)(dian)(dian)(dian)(dian)感(gan)的(de)(de)尺寸(cun)大小(xiao)(xiao)與其電(dian)(dian)(dian)(dian)(dian)氣(qi)性(xing)能沒有直接關系，并不(bu)意味(wei)著尺寸(cun)越(yue)大電(dian)(dian)(dian)(dian)(dian)氣(qi)性(xing)能越(yue)好(hao)。尺寸(cun)越(yue)小(xiao)(xiao)，電(dian)(dian)(dian)(dian)(dian)氣(qi)性(xing)能越(yue)差。

拋開電氣性能不(bu)談，我們看看貼片功率電感的尺寸(cun)是(shi)否越(yue)大(da)(da)越(yue)好(hao)。硅鋁鐵磁環電感的尺寸(cun)和(he)規(gui)格(ge)對電感選(xuan)型的影響主(zhu)要反映在電路中(zhong)能否正確安裝。簡而(er)言之(zhi)，規(gui)格(ge)尺寸(cun)越(yue)大(da)(da)，則需(xu)要為板(ban)材預留更多的空間(jian)位置; 否則，規(gui)格(ge)尺寸(cun)越(yue)小。

在電(dian)(dian)(dian)感(gan)(gan)(gan)的(de)選(xuan)擇(ze)(ze)上，電(dian)(dian)(dian)路板對電(dian)(dian)(dian)感(gan)(gan)(gan)的(de)規(gui)格(ge)尺寸(cun)(cun)的(de)要求是(shi)一(yi)定(ding)的(de)，所(suo)以(yi)我們(men)在選(xuan)擇(ze)(ze)電(dian)(dian)(dian)感(gan)(gan)(gan)時(shi)只需要根據既定(ding)的(de)要求選(xuan)擇(ze)(ze)相應規(gui)格(ge)尺寸(cun)(cun)的(de)貼(tie)片(pian)功率電(dian)(dian)(dian)感(gan)(gan)(gan)即可。完全沒有必(bi)要單方面(mian)追求規(gui)格(ge)尺寸(cun)(cun)的(de)大小。 作為擁有19年國外品牌電(dian)(dian)(dian)感(gan)(gan)(gan)代工經(jing)驗的(de)國內(nei)電(dian)(dian)(dian)感(gan)(gan)(gan)廠(chang)商(shang)，在常規(gui)電(dian)(dian)(dian)感(gan)(gan)(gan)升(sheng)級(ji)方面(mian)積累了(le)豐富的(de)經(jing)驗，可為各(ge)行業提供一(yi)站式(shi)的(de)電(dian)(dian)(dian)感(gan)(gan)(gan)升(sheng)級(ji)解(jie)決方案(an)。
