一個(gè)容量比較大的電解電容器由一個(gè)容量等于C1的純電容C0和一個(gè)電感L0(等效電感)串聯(lián)而成。在等效電路中，由于大容量的電解電容器還有一個(gè)等效電感L0的存在，當(dāng)頻率較高時(shí)純電容C0的容抗很小，但是L0的感抗較大(頻率越高，感抗越大)，結(jié)果大電容器總的阻抗高頻時(shí)不是減小，反而增大，這說(shuō)明大容量的電解電容器的高頻特性差。等效電感L0產(chǎn)生的原因由電解電容器結(jié)構(gòu)可知，電容器兩極板由鋁箔(指鋁電解電容器)構(gòu)成，鋁箔是導(dǎo)體，為了減小電解電容器的體積而將鋁箔卷起來(lái)。由電感器結(jié)構(gòu)可知，將一個(gè)導(dǎo)體卷繞起來(lái)會(huì)出現(xiàn)電感。由于大容量電解電容器容量大，它的鋁箔更長(zhǎng)，卷繞得更多，這樣等效電感存在且大到不能忽視的程度，導(dǎo)致大容量電解電容器的高頻特性差。電解電容器漏電比較大特性從理論上講電容器兩極板之間絕緣，沒(méi)有電流流過(guò)，但是電解電容器的漏電比較大，兩極板之間有較大的電流流過(guò)。電容漏電說(shuō)明電容兩極板之間存在漏電阻，如圖1-36所示，漏電流是通過(guò)這一漏電阻從電容器的一個(gè)極板流到另一個(gè)極板的。圖1-36電容器漏電阻示意圖漏電流比較大說(shuō)明電容器兩極板之間的漏電阻較小。漏電阻大，則漏電流小。電解電容器的漏電流影響了電容器的性能，對(duì)信號(hào)的損耗比較大。</p><p> 濾波電容具體選擇什么容值要取決于你PCB上主要的工作頻率和可能對(duì)系統(tǒng)造成影響的諧波頻率，可以查一下相關(guān)廠商的電容資料或者參考廠商提供的資料庫(kù)軟件，根據(jù)具體的需要選擇。至于個(gè)數(shù)就不一定了，看你的具體需要了，多加一兩個(gè)也挺好的，暫時(shí)沒(méi)用的可以先不貼，根據(jù)實(shí)際的調(diào)試情況再選擇容值。如果你PCB上主要工作頻率比較低的話，加兩個(gè)電容就可以了，一個(gè)慮除紋波，一個(gè)慮除高頻信號(hào)。如果會(huì)出現(xiàn)比較大的瞬時(shí)電流，建議再加一個(gè)比較大的鉭電容。其實(shí)濾波應(yīng)該也包含兩個(gè)方面，也就是各位所說(shuō)的大容值和小容值的，就是去耦和旁路。原理我就不說(shuō)了，實(shí)用點(diǎn)的，一般數(shù)字電路去耦，用于10M以下；20M以上用1到10個(gè)uF，去除高頻噪聲好些，大概按C=1/f。旁路一般就比較的小了，一般根據(jù)諧振頻率一般為。說(shuō)到電容，各種各樣的叫法就會(huì)讓人頭暈?zāi)垦?，旁路電容，去耦電容，濾波電容等等，其實(shí)無(wú)論如何稱呼，它的原理都是一樣的，即利用對(duì)交流信號(hào)呈現(xiàn)低阻抗的特性，這一點(diǎn)可以通過(guò)電容的等效阻抗公式看出來(lái)：Xcap=1/2лfC，工作頻率越高，電容值越大則電容的阻抗越小。在電路中，如果電容起的主要作用是給交流信號(hào)提供低阻抗的通路，就稱為旁路電容。牛角電容是怎么做成這么大的？</p><div
