內(nei)部電(dian)(dian)(dian)極通過逐(zhu)層(ceng)堆(dui)疊，增加電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)兩極板的(de)(de)面(mian)積，從而增加電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)容(rong)(rong)(rong)(rong)量(liang)(liang)。陶(tao)瓷(ci)介質是(shi)(shi)內(nei)部填充介質，不同介質制成的(de)(de)電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)具(ju)有(you)不同的(de)(de)特(te)(te)性，如容(rong)(rong)(rong)(rong)量(liang)(liang)大(da)、溫度特(te)(te)性好、頻率特(te)(te)性好等等，這(zhe)也是(shi)(shi)陶(tao)瓷(ci)電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)種類繁多的(de)(de)原因。陶(tao)瓷(ci)電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)基本參(can)數：電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)的(de)(de)單(dan)位:電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)的(de)(de)基本單(dan)位是(shi)(shi)F(法)，此(ci)外(wai)還有(you)F(微(wei)法)、nF、pF(微(wei)微(wei)法)。因為電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)F的(de)(de)容(rong)(rong)(rong)(rong)量(liang)(liang)很大(da)，所以我們(men)通常看到的(de)(de)是(shi)(shi)F、nF、pF的(de)(de)單(dan)位，而不是(shi)(shi)F。它們(men)之間的(de)(de)具(ju)體(ti)轉換如下：1F＝1000000μF1μF=1000nF=1000000pF北京全固態電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)廠家(jia)直銷MLCC電(dian)(dian)(dian)容(rong)(rong)(rong)(rong)特(te)(te)點： 機(ji)械強度：硬(ying)而脆，這(zhe)是(shi)(shi)陶(tao)瓷(ci)材(cai)料的(de)(de)機(ji)械強度特(te)(te)點。

如何(he)抑制(zhi)“嘯(xiao)叫”現象：1.降壓電(dian)(dian)(dian)(dian)源(yuan)通(tong)常有PWM和(he)PFM工作模(mo)式(shi)。PWM模(mo)式(shi)下紋波小，在高(gao)負(fu)(fu)載功耗條件下使用。為了避(bi)(bi)免(mian)BUCK在PWM模(mo)式(shi)下充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)容的(de)(de)(de)開關頻(pin)(pin)(pin)率引(yin)起的(de)(de)(de)嘯(xiao)叫，有些電(dian)(dian)(dian)(dian)源(yuan)的(de)(de)(de)開關頻(pin)(pin)(pin)率會刻意避(bi)(bi)開20hz~20Khz的(de)(de)(de)開關頻(pin)(pin)(pin)率。2.當(dang)電(dian)(dian)(dian)(dian)源(yuan)處于輕載模(mo)式(shi)時，會間(jian)(jian)(jian)歇工作，間(jian)(jian)(jian)歇輸出幾個脈(mo)沖。這(zhe)種間(jian)(jian)(jian)歇脈(mo)沖的(de)(de)(de)頻(pin)(pin)(pin)率也(ye)可(ke)以(yi)被(bei)人耳聽(ting)到。因此，從電(dian)(dian)(dian)(dian)源(yuan)或負(fu)(fu)載的(de)(de)(de)角度來看，PFM工作時間(jian)(jian)(jian)歇脈(mo)沖的(de)(de)(de)工作頻(pin)(pin)(pin)率應(ying)進(jin)行優化(hua)，以(yi)避(bi)(bi)免(mian)嘯(xiao)叫。3.另一種是隱藏狀態。在項目初(chu)期，系統(tong)往往不穩定(ding)，負(fu)(fu)載在正(zheng)常和(he)低功耗模(mo)式(shi)之間(jian)(jian)(jian)反復切換，電(dian)(dian)(dian)(dian)源(yuan)也(ye)很容易在PWM和(he)PFM模(mo)式(shi)之間(jian)(jian)(jian)切換。這(zhe)種切換的(de)(de)(de)時隙也(ye)可(ke)能(neng)引(yin)起嘯(xiao)叫，需要軟件優化(hua)系統(tong)的(de)(de)(de)穩定(ding)性，避(bi)(bi)免(mian)負(fu)(fu)載工作模(mo)式(shi)的(de)(de)(de)異常切換，避(bi)(bi)免(mian)嘯(xiao)叫。電(dian)(dian)(dian)(dian)容做為電(dian)(dian)(dian)(dian)氣、電(dian)(dian)(dian)(dian)子元器件對(dui)于我(wo)們這(zhe)些電(dian)(dian)(dian)(dian)工人來講(jiang)是非常熟悉(xi)的(de)(de)(de)。
