要是將電容器杜絕管道就一定安全性。但是真實(shí)相關(guān)電容器質(zhì)量的好多個(gè)關(guān)鍵主要參數(shù)，卻都只存有原裝說(shuō)明書(shū)中，徹底不容易顯出在制成品封裝表皮上，而這種關(guān)鍵主要參數(shù)才算是文中討論的關(guān)鍵。散逸因素——損害角損害角，不*有損害，自然愈低越好。塑膠電容的損害角很低，但鋁電解電容就非常高。DF值是高還是低，就同一**品牌、同一系列的電容器而言，與溫度、容量、工作電壓、頻率……都是有關(guān)聯(lián)；當(dāng)容量同樣時(shí)，耐壓愈高的DF值就愈低。舉案例做表明，同廠牌同系列產(chǎn)品的10000μF電容，耐壓80V的DF值一定比耐壓63V的低。采用過(guò)濾電容總會(huì)找較高耐壓者，并不是沒(méi)有大道理。除此之外溫度愈高DF值愈高，頻率愈高DF值也會(huì)愈高。但很多電容器生產(chǎn)廠，在說(shuō)明書(shū)常常不標(biāo)明散逸因素DF值，由于標(biāo)值甚高很不好看。以H-cao為例子，其深藍(lán)色PHE-420系列產(chǎn)品是MKP塑膠電容，它的DF值**少是**大是。但白前列PEH169系列產(chǎn)品鋁制電解法電容，就未標(biāo)識(shí)損害角規(guī)格型號(hào)。要是標(biāo)明DF值，很有可能會(huì)是，小數(shù)位是在1的後面。漏…漏電流走電！**好是沒(méi)有。但是沒(méi)法，鋁電解電容在工作中時(shí)一定會(huì)造成漏電流。漏電流(leakagecurrent)自然要低，電容器容量越高，漏電流就越大。誰(shuí)在電解電容工廠上過(guò)班？中山超小型電解電容封裝</p><p
