avx鉭(tan)電(dian)(dian)容(rong)(rong)為了一(yi)個實(shi)際步履的(de)選用電(dian)(dian)容(rong)(rong)降(jiang)壓的(de)LED驅動電(dian)(dian)路(lu)﹕請留意﹐大部分使(shi)(shi)用電(dian)(dian)路(lu)中沒有銜接壓敏電(dian)(dian)阻或瞬變電(dian)(dian)壓按捺晶體(ti)管(guan)﹐avx鉭(tan)電(dian)(dian)容(rong)(rong)的(de)選用電(dian)(dian)容(rong)(rong)降(jiang)壓電(dian)(dian)路(lu)是一(yi)種(zhong)常(chang)見的(de)小電(dian)(dian)流電(dian)(dian)源(yuan)電(dian)(dian)路(lu)﹐由于其具有體(ti)積小﹑本錢低﹑電(dian)(dian)流相對穩(wen)定等長處﹐也(ye)常(chang)使(shi)(shi)用于LED的(de)驅動電(dian)(dian)路(lu)中。

主張銜接上,因壓敏電阻或瞬變電壓按捺晶體管能在電壓驟變瞬間 如雷電﹑大用電設備起動等有效地將驟變電流泄放﹐然后保護二級關和其它晶體管﹐它們的呼應時間一般在微毫秒級。正弦波在最大峰值時刻被堵截時﹐電容C1上的殘存電荷無法開釋﹐會長久存在﹐C2﹑C3的效果為濾波﹐其效果是將整流后的脈動直流電壓濾波成平穩直流電壓。
