avx鉭(tan)電(dian)(dian)(dian)(dian)容(rong)(rong)作業頻(pin)率與電(dian)(dian)(dian)(dian)容(rong)(rong)類型不匹配； 在VHF電(dian)(dian)(dian)(dian)路中，因為(wei)電(dian)(dian)(dian)(dian)路作業頻(pin)率高(gao)，電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)(dian)感(gan)量會增加，容(rong)(rong)量會下(xia)降。 因而，有必要運用具有極低電(dian)(dian)(dian)(dian)感(gan)和(he)阻(zu)抗 ESR的(de)(de)(de)多層陶瓷(ci)電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)。低頻(pin)濾(lv)波電(dian)(dian)(dian)(dian)路有必要運用貼片鉭(tan)電(dian)(dian)(dian)(dian)容(rong)(rong)，因為(wei)MLCC在低頻(pin)時濾(lv)波作用很差。合適的(de)(de)(de)作業頻(pin)率與電(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)(qi)阻(zu)抗和(he)容(rong)(rong)量的(de)(de)(de)改變(bian)之間存在以下(xia)數學聯系；  avx鉭(tan)電(dian)(dian)(dian)(dian)容(rong)(rong)是電(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)(de)等(deng)效串聯電(dian)(dian)(dian)(dian)阻(zu)。

不同類型電容器的 ESR差異很大。 依據上面的公式，能夠得出這樣的結論；因為ESR不同，不同類型的電容器適用于不同頻率的濾波電路。不僅是體積，還有體積容量比的問題。 因而，有必要依據電路中需求濾除的紋波頻率，挑選不同阻抗ESR范圍的電容。 容量挑選只考慮信號呼應的速度。 否則，過濾作用將達不到規劃要求。
