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(zhuān)業(yè)類(lèi)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。

ESR）。等效串聯(lián)電阻會(huì)影響元件的阻抗：圖：阻抗公式1）隨著頻率接近無(wú)限大，電容器的阻抗（或容抗）會(huì)減小，而會(huì)以ESR為主。當(dāng)容抗可忽略，其消耗功率為PRMS=VRMS2/）和ESR類(lèi)似的，電容器的導(dǎo)線也會(huì)產(chǎn)生等效串聯(lián)電感（ESL），一般只在相對(duì)高頻時(shí)才比較有影響。電感感抗是正的，會(huì)隨頻率增加，超過(guò)一定頻率后，電容會(huì)被電感所抵消。高頻電子學(xué)就需要計(jì)算所有接線以及元件的電感量。3）若電容器的二個(gè)導(dǎo)體之間不是理想的介電質(zhì)，而是導(dǎo)電性較低的材料，會(huì)產(chǎn)生微小的漏電流。因此電容器會(huì)有一個(gè)有限的并聯(lián)電阻，會(huì)慢慢的放電（放電時(shí)間依電容器材料及品質(zhì)而定）。（3）品質(zhì)因子電容器的品質(zhì)因子（或Q因子）是特定頻率下其容抗和電阻的比例，用來(lái)量測(cè)其效率。Q值越大的電容器，其特性越接近理想電容器。電容器的Q因子可以用下式計(jì)算：圖：品質(zhì)因子公式其中ω是角頻率，C是電容，Xc是容抗，R是電容器的等效電阻（ESR）。（4）紋波電流紋波電流是電源（例如開(kāi)關(guān)模式電源）的交流電流成分，其頻率可能是定值，也可能會(huì)變動(dòng)。紋波電流會(huì)使電容器發(fā)熱，原因一方面是因?yàn)榻殡娰|(zhì)上電場(chǎng)變化造成的能量損失，再加上電流通過(guò)有微小電阻的導(dǎo)線或電解質(zhì)的損失。等效串聯(lián)電阻。AFMRr電容器質(zhì)量哪家好，歡迎來(lái)電咨詢(xún)，無(wú)錫市錫容電力電器有限公司。浙江自愈式電容器廠</p><p
