抗壓愈高的DF值就愈低。頻率愈高DF值愈高，溫度愈高DF值也愈高。DF值一般不標(biāo)明在電容器上或規(guī)格型號詳細(xì)介紹上邊。在DIY選擇電容時，可優(yōu)先選擇考慮到選擇高些抗壓的，例如工作標(biāo)準(zhǔn)電壓為45V時，采用50V的也不很有效。雖然應(yīng)用50V的從承擔(dān)工作電壓一切正常工作中方面并無不當(dāng)之處，但從DF值層面考慮到就缺乏一些。應(yīng)用63V或71V抗壓的會出現(xiàn)更強的主要表現(xiàn)的。自然再高了性價比高上就不劃算了。5.漣波電流量Irac漣波電流量針對石機的低通濾波器而言，是一個很重要的主要參數(shù)。漣波電流量Irac是愈高越好。他的高矮與輸出功率有關(guān)，頻率越高Irac越大，頻率越低Irac越小。傳統(tǒng)式的覺得大家必須在低頻時可以有很高的漣波電流量，而求獲得優(yōu)良的大電流量充放電特點，使的低頻更為牢固圓潤頗具延展性，及其優(yōu)良的操縱驅(qū)動器特點；事實上在高頻率時高的漣波電流量對音質(zhì)的正臉協(xié)助也非常大，能夠使高頻率有更強的拓寬和減少不光滑感。電解電容的特點主要參數(shù)一、允差電容量和容許誤差允差電容量是標(biāo)示在電容器上的電容量。電容器具體電容量與允差電容量的誤差稱誤差，在容許的誤差范疇稱精密度。精度級別與容許誤差對應(yīng)關(guān)系：00（01）-±1%、0。廣州超小型電解電容正負(fù)極</p><p
