avx鉭電容的太高存正在取鉭電容器使用正在存正在太高交流紋波的濾波電路,即便是使用電壓近低于 應當的降額幅度, 無意偶然候,正在開機的霎時仍然會發生發火突然的擊脫征象; 出現此類成果的非有必要原因原由是電容器的 ESR 戰電路中的交流紋波大小嚴重沒有婚配. 電容器是極性元氣件,正在通過進程交 流紋波時會發熱,而不同殼號大小的產品可以保持熱均衡的容許發熱量不同.

一(yi)樣,如(ru)果(guo)電(dian)(dian)(dian)(dian)(dian)路(lu)中的(de)交流(liu)紋波必(bi)定,而挑選的(de)鉭電(dian)(dian)(dian)(dian)(dian)容(rong)器的(de)實踐ESR值太高,產品也(ye)會出(chu)現不(bu)異(yi)的(de)征象(xiang).關于普通來講(jiang),正在濾(lv)波戰(zhan)年夜功率(lv)充放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)路(lu),有必(bi)要使(shi)用 ESR 值盡量(liang)低的(de)鉭電(dian)(dian)(dian)(dian)(dian)容(rong)器. 關于電(dian)(dian)(dian)(dian)(dian)路(lu)中 存(cun)(cun)正在的(de)交流(liu)紋波太高而引(yin)起(qi)的(de)電(dian)(dian)(dian)(dian)(dian)容(rong)器收效成果(guo),許多電(dian)(dian)(dian)(dian)(dian)路(lu)想(xiang)象(xiang)師皆疏(shu)忽(hu)其風(feng)險性(xing)或認識不(bu)足. 僅(jin)僅(jin)簡單確(que)定電(dian)(dian)(dian)(dian)(dian)容(rong)器量(liang)量(liang)存(cun)(cun)正在成果(guo). 此(ci)征象(xiang)許多.
