1，電容器的簡介（1）電容器（英文：capacitor，又稱為condenser）是將電能儲存在電場中的被動電子元件。電容器的儲能特性可以用電容表示。在電路中鄰近的導(dǎo)體之間即存在電容，而電容器是為了增加電路中的電容量而加入的電子元件。（2）電容器的外型以及其構(gòu)造依其種類而不同，目前常使用的電容器也有許多不同種類，大部分的電容至少會有二個金屬板或是金屬表面的導(dǎo)體，中間有介電質(zhì)隔開。導(dǎo)體可以是金屬箔、薄膜、燒結(jié)金屬珠或是電解質(zhì)。無導(dǎo)電性的介電質(zhì)可以增加電容器的儲電能力。常見的介電質(zhì)有玻璃、陶瓷器、塑膠膜、紙、云母及氧化物。在許多的電路中都會用到電容器。電容器和電阻器不同，理想的電容器不會消耗能量。圖：電容器2，電容器的歷史發(fā)展（1）歷史上個有留下記錄的電容器由克拉斯特主教在1745年10月所發(fā)明，是一個內(nèi)外層均鍍有金屬膜的玻璃瓶，玻璃瓶內(nèi)有一金屬桿，一端和內(nèi)層的金屬膜連結(jié)，另一端則連結(jié)一金屬球體。借由在二層金屬膜中利用玻璃作為絕緣的方式，克拉斯特主教讓電荷密度出現(xiàn)明顯的提升。（2）1746年1月，荷蘭物理學(xué)家彼得·范·穆森布羅克也發(fā)明了構(gòu)造非常類似的電容器，當(dāng)時克拉斯特主教的發(fā)明尚未廣為人知。江蘇BAMR電容器供貨商BFF電容器質(zhì)量哪家好，歡迎來電咨詢，無錫市錫容電力電器有限公司。</p><div

要給大家講解的是電容器。半導(dǎo)體的一個分支，多數(shù)人不太理解，科技股特別是半導(dǎo)體近兩個月的走勢相對弱勢，市場中之前出現(xiàn)過食品飲料，前段時間的順周期都漲得挺好的，為什么要關(guān)注半導(dǎo)體？順周期之前我在《一起讀研報》中連續(xù)講解的2—3期，從鈦白粉到化工漲價，再到小金屬，當(dāng)時講解的時候順周期還沒有上漲，多數(shù)人也不知道什么叫順周期，也可能聽不太懂我講解的詳細(xì)內(nèi)容是什么。隨后順周期的上漲了，整個資本市場都在討論順周期，股民也知道順周期了。知道的原因是化工、煤炭、有色都已經(jīng)漲的很高了。這時候也想起來關(guān)注了，也開始研究了，是不是就已經(jīng)晚了？因為當(dāng)所有人開始關(guān)注的時候，股價就會開始回落，順周期如此，之前的券商也是如此。挖掘沒有被市場發(fā)現(xiàn)的，行業(yè)的內(nèi)生邏輯非常確定的，未來有可能上漲，做前瞻性的布局，才有真正的意義。為什么在這關(guān)注半導(dǎo)體的分支電容器，就是如此。因為晶圓制造漲價50%，封裝測試漲價30%。電容器在近期也開始漲價，而且漲價速度非?？?，這時候價值就已經(jīng)開始顯性，市場還沒有反應(yīng)。半導(dǎo)體分為——集成電路——被動元器件——功率元器件，也可以理解為主動元器件和被動元器件，我們之前更多的關(guān)注的是集成電路中的芯片。</p><p> 那么就來探索下j為什么對應(yīng)了角度。因為j是復(fù)數(shù)，那先讓我們看下復(fù)數(shù)定義：對于任意實數(shù),x,y形如：z=x+jy的數(shù)為復(fù)數(shù)。x是實部y是虛部。跟向量一樣它可以用平面坐標(biāo)表示，這個平面叫做復(fù)平面。其中利用直角坐標(biāo)與極坐標(biāo)的關(guān)系：因此復(fù)數(shù)z=x+jy還可以表示為：在利用神奇的歐拉公式：那么復(fù)數(shù)z=x+jy還可以表示為：在極坐標(biāo)下我們知道一個向量可以由模值和角度表示，同理是復(fù)數(shù)的的極坐標(biāo)表示。r是模值，φ是角度。為什么要用極坐標(biāo)表示呢，因為在這種表示法下，計算會很簡單。舉個例子：乘除法和微分計算：在電路系統(tǒng)研究中我們喜歡用正弦函數(shù)Acos(wt+φ)作為激勵源（輸入）,因為它的形式比較簡單，理論研究的很透徹，并且根據(jù)傅里葉變換所有的波形都可以由多個正弦函數(shù)疊加表示。因此我們也用正弦函數(shù)作為激勵來研究穩(wěn)態(tài)下的電容電路，這里有個名詞叫做正弦穩(wěn)態(tài)分析（注：在電路研究中我們喜歡把cos叫做正弦，但不影響我們對問題的研究）。正弦函數(shù)有三個特征即：幅度A，角頻率w和初相φ，知道了這三個特征后，就確定一個正弦函數(shù)。在正弦穩(wěn)態(tài)電路中信號的頻率是不會改變的，即輸入是的正弦，輸出的還是的正弦，只是幅度和相位可能會發(fā)生變化。AFM電容器質(zhì)量哪家好，歡迎來電咨詢，無錫市錫容電力電器有限公司。</p><div

則電流瞬間流向?qū)Ь€，對電容器進(jìn)行充電；當(dāng)電極間的電位差與電源電壓相等，則電流不再流動，充電結(jié)束。充放電過程如下圖所示。圖：電容器的充放電圖：電容器蓄電（2）阻直流，通交流電容器的電極被電介質(zhì)阻隔，施加直流電壓后，在充電過程中電流瞬間流過導(dǎo)線，但不會流到電介質(zhì)的內(nèi)部。即，電容器具有阻斷直流的性質(zhì)。連接交流電源，則電極板周期性地反復(fù)進(jìn)行充電與放電，電場方向也會相應(yīng)地發(fā)生改變。雖然不是在絕緣體內(nèi)部出現(xiàn)電子移動，但實際上與流過交流電流相同，因此可視為電容器使交流電流通過。相對于通常的電流（傳導(dǎo)電流），我們將該電流稱為位移電流。圖：阻直流圖：通交流（3）容抗特性頻率越高，電容量越大，交流電越容易通過，這是電容器的又一基本特性。阻直流通交流是電容器的基本性質(zhì)，但并非所有交流電都一樣通過，通過的阻礙由交流電的頻率與電容器的電容量決定。該交流電通過阻礙叫做容抗(Xc)，是電容器對交流電的阻抗，單位是歐姆[?]。電容器的容抗(Xc)以如下公式表示。圖：容抗計算公式圖：容抗頻率特性6，電容器的參數(shù)特性實際的電容器和理想電容器的特性方程是有些差異的。其中有些特性（像是漏電流以及雜散效應(yīng)）是線性的。低壓電容器質(zhì)量哪家好，歡迎來電咨詢，無錫市錫容電力電器有限公司。江蘇AFM電容器廠</p><p

由于馬森布魯克當(dāng)時在萊頓大學(xué)任教，因此將其命名為萊頓瓶。（3）當(dāng)時人們認(rèn)為，電荷是儲存在萊頓瓶中的水里；但美國科學(xué)家富蘭克林研究萊頓瓶，證明其電荷是儲存在玻璃上，并非儲存在萊頓瓶中的水里。3，電容器的定義電容器的電容（C）是測量當(dāng)電容器兩端的電勢差或電壓（V）為單位值時，儲存在電容器電極的電荷量（Q）：圖：電荷量公式若根據(jù)國際單位制，若一電容器兩極施加一伏特的電壓，其儲存電荷量為一庫侖，則此電容器的電容量為一法拉（F），在實際應(yīng)用中，法拉是相當(dāng)大的單位，一般情況下，電容器的電容量常常以毫法拉（mF,1mF=10^-3F）、微法拉（μF,1μF=10^-6F）、奈法拉（nF,1nF=10^-9F）或皮法拉（pF,1pF=10^-12F）來表示。電容量和電極的面積成正比，和二電極之間的距離成反比。電容量也和二電極間介電質(zhì)的相對電容率成正比。平行板電容器的電容量如下式：圖：電容量公式4，電容器的標(biāo)示電容器是一種容納電荷的器件，通常電容器也會有一些標(biāo)志，根據(jù)標(biāo)注可以更好的學(xué)習(xí)和使用電容器，接下來講解一下電容器的四種標(biāo)示方法：（1）直標(biāo)法電容器在出廠以前就在本體表面印上了廠家標(biāo)志，型號，標(biāo)稱容量，允許誤差范圍，額定工作電壓等。下圖為直接標(biāo)注法。麗水OAF電容器哪家好</p><p
