充(chong)電器在(zai)充電時(shi)如遇上劣質充電器(qi)會出現無(wu)故自(zi)燃，爆手機(ji)，甚至是(shi)在(zai)充電時(shi)觸電，引發人員傷忙。這一(yi)切都源于充電器(qi)中(zhong)的電子(zi)元器(qi)件的品質問(wen)題。手機(ji)充電器(qi)y電容(rong)用于共(gong)模濾(lv)(lv)波，它接于L于地(di)(di)或(huo)N于地(di)(di)之間(jian)，濾(lv)(lv)除L對(dui)地(di)(di)或(huo)N對(dui)地(di)(di)的共(gong)模信號，y電容(rong)通(tong)常對(dui)稱使用，作(zuo)用主要有旁路(lu)；去耦(ou)；濾(lv)(lv)波；儲能。

在(zai)入力初級端有(you)個耐壓(ya)(ya)(ya)(ya)400v的(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)，那是(shi)(shi)主濾(lv)(lv)波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)，濾(lv)(lv)除市電(dian)(dian)(dian)(dian)(dian)(dian)整流(liu)后(hou)的(de)雜波(bo)，使(shi)后(hou)面(mian)(mian)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)能(neng)得到(dao)更為(wei)平(ping)穩的(de)直(zhi)流(liu)正弦(xian)波(bo)，只有(you)雜波(bo)越(yue)少，電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)才能(neng)更好(hao)的(de)穩定(ding)工作，至于電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)選(xuan)(xuan)400v耐壓(ya)(ya)(ya)(ya)值，開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)工作后(hou)，其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)兩(liang)端將(jiang)有(you)300多(duo)伏壓(ya)(ya)(ya)(ya)降，再加上通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)瞬間峰(feng)值電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，所(suo)以如(ru)果耐壓(ya)(ya)(ya)(ya)值太(tai)小(xiao)(xiao)，會影起電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)暴(bao)裂(lie)，而輸出(chu)端電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)視其(qi)輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)大小(xiao)(xiao)選(xuan)(xuan)擇(ze)適合的(de)耐壓(ya)(ya)(ya)(ya)值，如(ru)5v則耐壓(ya)(ya)(ya)(ya)值是(shi)(shi)10v，該電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)也是(shi)(shi)濾(lv)(lv)波(bo)作用，使(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)輸出(chu)平(ping)穩的(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)，至于容(rong)(rong)量(liang)的(de)大小(xiao)(xiao)，前(qian)面(mian)(mian)耐壓(ya)(ya)(ya)(ya)大的(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)一般選(xuan)(xuan)擇(ze)47~470uF，輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)一般100~1000uF，原則上是(shi)(shi)容(rong)(rong)量(liang)越(yue)大越(yue)好(hao)，但實際上容(rong)(rong)量(liang)越(yue)大漏電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)越(yue)大，y電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)通(tong)交流(liu)阻直(zhi)流(liu)。所(suo)以我們(men)為(wei)手機充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)時要(yao)選(xuan)(xuan)擇(ze)質(zhi)量(liang)好(hao)的(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)。而y電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)品(pin)質(zhi)好(hao)壞直(zhi)接(jie)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)質(zhi)量(liang)。
作為手機充電器中的(de)(de)y電容(rong)，質(zhi)量保障是很重要的(de)(de)，選(xuan)購(gou)y電容(rong)時選(xuan)擇必須有安全檢(jian)測機構的(de)(de)認(ren)證和各工(gong)業國的(de)(de)安規認(ren)證，一般產品上(shang)都有認(ren)證標識。
