avx鉭電容的電阻與瞬間克制的字體來說，關于用法輸入電源中瞬間的脈沖高壓電壓對地泄放掉﹐然后保護LED不被瞬間高壓擊穿。電容降壓電源原理及相關核算----合用于低單價、抗干擾要求較低的電路略有補充，將交流市電轉換為低壓直流的常規辦法是選用變壓器降壓后再整流濾波，當受體積和本錢等要素的約束同時，能夠用最儉樸實用的辦法就是選用電容降壓式電源。

LED串(chuan)聯的(de)(de)數目視其(qi)正(zheng)導游通電壓(ya)而(er)定(ding)﹐在(zai)(zai)220V電路中(zhong)﹐最(zui)多(duo)能(neng)夠(gou)(gou)達(da)到80個左右。組件(jian)挑選(xuan)﹕電容(rong)(rong)(rong)(rong)(rong)的(de)(de)耐壓(ya)一(yi)般(ban)要求大于(yu)輸入(ru)電源電壓(ya)的(de)(de)峰值﹐在(zai)(zai)220V,50Hz的(de)(de)交(jiao)流電路中(zhong)時﹐能(neng)夠(gou)(gou)挑選(xuan)耐壓(ya)為400伏以上的(de)(de)滌綸電容(rong)(rong)(rong)(rong)(rong)或紙(zhi)介質(zhi)電容(rong)(rong)(rong)(rong)(rong)。avx鉭電容(rong)(rong)(rong)(rong)(rong)的(de)(de)電容(rong)(rong)(rong)(rong)(rong)器與(yu)容(rong)(rong)(rong)(rong)(rong)量(liang)是(shi)不亂(luan)的(de)(de)，在(zai)(zai)可(ke)用(yong)作高精度的(de)(de)電容(rong)(rong)(rong)(rong)(rong)器，但體積(ji)較大，工(gong)作溫度不宜超越70□；聚丙烯電容(rong)(rong)(rong)(rong)(rong)器工(gong)作溫度可(ke)達(da) 125□，而(er)聚四氟乙烯電容(rong)(rong)(rong)(rong)(rong)器可(ke)達(da)200□，但價格較貴。
