充電器在充(chong)(chong)電(dian)時如遇上劣(lie)質充(chong)(chong)電(dian)器會(hui)出(chu)現(xian)無故(gu)自燃，爆手(shou)機(ji)，甚(shen)至是在充(chong)(chong)電(dian)時觸電(dian)，引發(fa)人員傷忙。這一切都源于(yu)充(chong)(chong)電(dian)器中的(de)電(dian)子(zi)元(yuan)器件的(de)品質問題(ti)。手(shou)機(ji)充(chong)(chong)電(dian)器y電(dian)容用(yong)(yong)于(yu)共模濾波(bo)，它接于(yu)L于(yu)地或(huo)N于(yu)地之間，濾除(chu)L對(dui)(dui)地或(huo)N對(dui)(dui)地的(de)共模信號，y電(dian)容通常(chang)對(dui)(dui)稱使用(yong)(yong)，作用(yong)(yong)主要(yao)有旁路；去耦；濾波(bo)；儲能。

在入力初級端有(you)個(ge)耐(nai)壓(ya)(ya)(ya)400v的(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)，那(nei)是(shi)主濾波(bo)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)，濾除市(shi)電(dian)(dian)(dian)(dian)(dian)整流(liu)(liu)后的(de)(de)雜波(bo)，使后面電(dian)(dian)(dian)(dian)(dian)路(lu)能(neng)得(de)到更為(wei)平穩的(de)(de)直流(liu)(liu)正弦波(bo)，只(zhi)有(you)雜波(bo)越(yue)少(shao)，電(dian)(dian)(dian)(dian)(dian)路(lu)才能(neng)更好(hao)(hao)的(de)(de)穩定(ding)工作(zuo)，至于(yu)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)選(xuan)400v耐(nai)壓(ya)(ya)(ya)值(zhi)，開關(guan)電(dian)(dian)(dian)(dian)(dian)路(lu)工作(zuo)后，其電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)兩端將有(you)300多伏壓(ya)(ya)(ya)降，再加上(shang)(shang)通(tong)(tong)電(dian)(dian)(dian)(dian)(dian)瞬間峰值(zhi)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，所(suo)以如果(guo)耐(nai)壓(ya)(ya)(ya)值(zhi)太小，會(hui)影起電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)暴裂，而輸(shu)出(chu)端電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)視其輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)大(da)(da)小選(xuan)擇適(shi)合(he)的(de)(de)耐(nai)壓(ya)(ya)(ya)值(zhi)，如5v則耐(nai)壓(ya)(ya)(ya)值(zhi)是(shi)10v，該電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)也是(shi)濾波(bo)作(zuo)用，使充電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)輸(shu)出(chu)平穩的(de)(de)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，至于(yu)容(rong)(rong)(rong)量(liang)的(de)(de)大(da)(da)小，前面耐(nai)壓(ya)(ya)(ya)大(da)(da)的(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)一般選(xuan)擇47~470uF，輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)一般100~1000uF，原則上(shang)(shang)是(shi)容(rong)(rong)(rong)量(liang)越(yue)大(da)(da)越(yue)好(hao)(hao)，但實際上(shang)(shang)容(rong)(rong)(rong)量(liang)越(yue)大(da)(da)漏電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)越(yue)大(da)(da)，y電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)通(tong)(tong)交流(liu)(liu)阻直流(liu)(liu)。所(suo)以我(wo)們為(wei)手機充電(dian)(dian)(dian)(dian)(dian)時要選(xuan)擇質(zhi)量(liang)好(hao)(hao)的(de)(de)充電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)。而y電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)的(de)(de)品質(zhi)好(hao)(hao)壞(huai)直接充電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)質(zhi)量(liang)。
作為手(shou)機(ji)(ji)充(chong)電器中的y電容，質(zhi)量保障是(shi)很重要的，選(xuan)購y電容時選(xuan)擇必須有安(an)全(quan)檢測機(ji)(ji)構的認(ren)證和各(ge)工(gong)業國的安(an)規(gui)認(ren)證，一般(ban)產(chan)品上(shang)都有認(ren)證標識。
手機充電(dian)器(qi)y電(dian)容(rong)，y電(dian)容(rong)，jec y電(dian)容(rong)，y電(dian)容(rong)器(qi)
　　手(shou)機充電(dian)器y電(dian)容(rong)(rong)(rong)用于共模濾波，原則上是容(rong)(rong)(rong)量越大越好.但實際上容(rong)(rong)(rong)量越大漏電(dian)流(liu)越大，y電(dian)容(rong)(rong)(rong)通交(jiao)流(liu)阻直流(liu).所以我們為手(shou)機充電(dian)時要選擇(ze)質(zhi)量好的(de)(de)充電(dian)器，而y電(dian)容(rong)(rong)(rong)的(de)(de)品質(zhi)好壞(huai)直接充電(dian)器的(de)(de)質(zhi)量.
