ESR）就是考慮這些損耗的影響。有一些種類的電容器，包括鋁和鉭的電解電容器，以及一些薄膜電容器的規(guī)格會(huì)包括大的紋波電流：1）若是用固態(tài)二氧化錳為介電質(zhì)的鉭質(zhì)電容器，其允許紋波電流有一定限制，在電容中的ESR也是高的。若紋波電流超過(guò)額定值，會(huì)造成短路，并且損毀其他元件。2）鋁電解電容是常用的電解電容，若紋波電流較高，其壽命會(huì)降低。若紋波電流超過(guò)額定值，電容會(huì)爆裂。3）陶瓷電容器一般沒(méi)有紋波電流的限制，其ESR小。4）薄膜電容器的ESR也非常低，但若紋波電流超過(guò)額定值，會(huì)造成電容器的退化。（5）電容量穩(wěn)定性1）有些電容的電容量會(huì)隨著元件老化而下降。針對(duì)陶瓷電容器而言，電容量的下降是因?yàn)榻殡娰|(zhì)的劣化而造成。介電質(zhì)種類、環(huán)境溫度以及儲(chǔ)存溫度都會(huì)影響老化，工作電壓的影響比較小，一般電容的設(shè)計(jì)也都會(huì)讓電壓系數(shù)降到小。元件老化的過(guò)程可以透過(guò)將元件加熱超過(guò)居里點(diǎn)來(lái)改善。在元件剛開(kāi)始工作時(shí)，老化的快，之后會(huì)隨著時(shí)間而漸漸穩(wěn)定。電解電容器會(huì)隨著電解液的蒸發(fā)而老化，和陶瓷電容器不同，其老化主要是元件壽命的末期出現(xiàn)。2）電容量和溫度的關(guān)系一般會(huì)用ppm每°C來(lái)表示。一般會(huì)是范圍很廣的線性函數(shù)，但在溫度極值時(shí)會(huì)有明顯的非線性。防護(hù)電容器質(zhì)量哪家好，歡迎來(lái)電咨詢，無(wú)錫市錫容電力電器有限公司。</p><div

電容的理論分析已經(jīng)完了，接下來(lái)讓我們看下常見(jiàn)的電容。1直插電容（Leadedcapacitor）幾乎所以電容都可以做成直插式，包括：電解電容，陶瓷電容，超級(jí)電容器，薄膜電容器，銀云母電容器，玻璃和其他專業(yè)類型電容器。直插電容一般有兩條腿，體積比貼片式的大，表面有數(shù)字字母等標(biāo)識(shí)。直插電容的機(jī)械、溫度等可靠性要優(yōu)于貼片電容，比如機(jī)械振動(dòng)大的場(chǎng)合盡量用直插電容。但是直插電容生產(chǎn)安裝焊接調(diào)試拆卸等比較復(fù)雜，體積較大，而且引線會(huì)帶來(lái)寄生電感影響高頻性能，比如射頻小型化領(lǐng)域基本都是用的表貼式的。12貼片電容（Surfacemountcapacitor）貼片電容的相對(duì)于直插電容更加受限，因?yàn)橘N片電容沒(méi)有引腳的緣故，在焊接過(guò)程中焊錫的高溫會(huì)直接加在電容上,因此并不是所有的電容都適合做成貼片式的。常見(jiàn)的貼片電容包括:陶瓷電容、鉭（tan）電容和電解電容。陶瓷電容上面沒(méi)有印字，鉭電容和電解電容上面都有印字，包括正極（有橫杠一邊）指示、容量、耐壓值和溫度等信息。貼片電容生產(chǎn)簡(jiǎn)單、成本低，并且焊接的時(shí)候使用SMT（Surfacemounttechnology），用回流焊，效率高，直插式的需要用波峰焊成本高。

一工作原理：電容器與電池類似，也具有兩個(gè)電極。在電容器內(nèi)部，這兩個(gè)電極分別連接到被電介質(zhì)隔開(kāi)的兩塊金屬板上。電介質(zhì)可以是空氣、紙張、塑料或其他任何不導(dǎo)電并能防止這兩個(gè)金屬極相互接觸的物質(zhì)。電容器上與電池負(fù)極相連的金屬板將吸收電池產(chǎn)生的電子。電容器上與電池正極相連的金屬板將向電池釋放電子。充電完成后，電容器與電池具有相同的電壓（如果電池電壓是，則電容器電壓也是）。二主要用途：1.電容器用于存儲(chǔ)電量以便高速釋放。閃光燈用到的就是這一功能。大型激光器也使用此技術(shù)來(lái)獲得非常明亮的瞬時(shí)閃光效果。2.電容器還可以消除脈動(dòng)。如果傳導(dǎo)直流電壓的線路含有脈動(dòng)或尖峰，大容量電容器可以通過(guò)吸收波峰和填充波谷來(lái)使電壓變得平穩(wěn)。3.電容器可以阻隔直流。如果將一個(gè)較小的電容器連接到電池上，則在電容器充電完成后（電容器容量較小時(shí)，瞬間即可完成充電過(guò)程），電池的兩極之間將不再有電流通過(guò)。然而，任何交流電流(AC)信號(hào)都可以暢通無(wú)阻地流過(guò)電容器。其原因是隨著交流電流的波動(dòng)，電容器不斷地充放電，就好像交流電流在流動(dòng)一樣。4.電容器與電感器一起使用，可構(gòu)成振蕩器?；窗睴AF電容器哪家好</p><p
