假如給你容量越大光滑實(shí)際效果越好的念頭，這一「漏電流」也請(qǐng)考慮到以內(nèi)。但減少電容器的漏電流并不易，漏電流規(guī)格型號(hào)，鋁電解電容就比鉭電解法電容差很多，鉭質(zhì)電容也是有乾式及濕試二種，但是它的容量及耐壓都較低。等效電路串聯(lián)電阻ESR一只電容器會(huì)以其結(jié)構(gòu)而造成各種各樣特性阻抗、感抗，較為關(guān)鍵的便是ESR等效電路串聯(lián)電阻及ESL等效電路串連電感器這就是容抗的基本。電容器出示電容量，ESR的高矮，與電容器的容量、工作電壓、頻率及溫度…都相關(guān)，當(dāng)額定電流固定不動(dòng)時(shí)，容量愈大ESR愈低。有些人習(xí)用將多個(gè)小電容并連接成一顆大電容以減少特性阻抗，其基礎(chǔ)理論是電阻并聯(lián)電阻值減少。但若考慮到電容接腳點(diǎn)焊的特性阻抗，以小并大，不一定一定會(huì)有獲得。Cs是電容量。有時(shí)候電容器規(guī)格型號(hào)上面有Z，它與ESR的實(shí)際意義不一樣，但Z的測(cè)算示與ESR相關(guān)，另外也充分考慮容抗及感抗，是真實(shí)的內(nèi)電阻。剛剛提及電容的ESR企業(yè)是mΩ，那就是指大電容，若是220μF小容量電容，其ESR企業(yè)就并不是mΩ只是Ω。哪種電容器的ESR**少？回答只有一個(gè)：Sanyo的。關(guān)於容量誤差，近些年鋁制電解法電容頗有發(fā)展，過(guò)去是-20％～+40％，如今大多數(shù)是+/-20％。但其容量常偏加而不是偏減。福州插件電解電容哪家好電解電容的詳細(xì)資料誰(shuí)有？</p><div
