了解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)使用注意事項：1.電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)有正(zheng)(zheng)(zheng)極(ji)(ji)(ji)和(he)負(fu)極(ji)(ji)(ji)，所以(yi)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中使用時(shi)不能顛倒聯接。在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中，輸出(chu)正(zheng)(zheng)(zheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)正(zheng)(zheng)(zheng)極(ji)(ji)(ji)接電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)輸出(chu)端，負(fu)極(ji)(ji)(ji)接地，輸出(chu)負(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)時(shi)則負(fu)極(ji)(ji)(ji)接輸出(chu)端，正(zheng)(zheng)(zheng)極(ji)(ji)(ji)接地．當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路中的(de)(de)濾波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)極(ji)(ji)(ji)性(xing)接反時(shi)，因(yin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)濾波(bo)作用較大降低，一方面(mian)引起電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)波(bo)動，另一方面(mian)又因(yin)反向(xiang)通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)使此時(shi)相當(dang)于一個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)發(fa)熱(re)．當(dang)反向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)超過某值時(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)的(de)(de)反向(xiang)漏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)將變(bian)得很小(xiao)，這(zhe)樣通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)工作不久，即可使電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)因(yin)過熱(re)而炸裂(lie)損壞。

如何抑制“嘯(xiao)叫”現象：1.降(jiang)壓(ya)電(dian)(dian)源通常(chang)有PWM和(he)PFM工(gong)(gong)作模(mo)(mo)式(shi)。PWM模(mo)(mo)式(shi)下紋波(bo)小，在高負(fu)載功耗條(tiao)件下使(shi)用(yong)。為了(le)避(bi)免(mian)(mian)BUCK在PWM模(mo)(mo)式(shi)下充電(dian)(dian)電(dian)(dian)容的開(kai)關(guan)頻(pin)率(lv)(lv)(lv)引起(qi)(qi)的嘯(xiao)叫，有些電(dian)(dian)源的開(kai)關(guan)頻(pin)率(lv)(lv)(lv)會刻意避(bi)開(kai)20hz~20Khz的開(kai)關(guan)頻(pin)率(lv)(lv)(lv)。2.當電(dian)(dian)源處于(yu)輕(qing)載模(mo)(mo)式(shi)時，會間(jian)(jian)(jian)歇(xie)工(gong)(gong)作，間(jian)(jian)(jian)歇(xie)輸出幾(ji)個脈沖。這種(zhong)間(jian)(jian)(jian)歇(xie)脈沖的頻(pin)率(lv)(lv)(lv)也(ye)可(ke)(ke)以(yi)被人耳聽(ting)到。因此，從(cong)電(dian)(dian)源或負(fu)載的角度(du)來看，PFM工(gong)(gong)作時間(jian)(jian)(jian)歇(xie)脈沖的工(gong)(gong)作頻(pin)率(lv)(lv)(lv)應進行優化，以(yi)避(bi)免(mian)(mian)嘯(xiao)叫。3.另一種(zhong)是隱(yin)藏(zang)狀態(tai)。在項目初期，系統往往不穩(wen)定(ding)，負(fu)載在正常(chang)和(he)低(di)功耗模(mo)(mo)式(shi)之間(jian)(jian)(jian)反復切換，電(dian)(dian)源也(ye)很容易在PWM和(he)PFM模(mo)(mo)式(shi)之間(jian)(jian)(jian)切換。這種(zhong)切換的時隙也(ye)可(ke)(ke)能(neng)引起(qi)(qi)嘯(xiao)叫，需要軟(ruan)件優化系統的穩(wen)定(ding)性(xing)，避(bi)免(mian)(mian)負(fu)載工(gong)(gong)作模(mo)(mo)式(shi)的異(yi)常(chang)切換，避(bi)免(mian)(mian)嘯(xiao)叫。MLCC 產業的下游(you)幾(ji)乎涵蓋了(le)電(dian)(dian)子(zi)工(gong)(gong)業全領域，如消費電(dian)(dian)子(zi)、工(gong)(gong)業、通信、汽車(che)等。
