該瞬時(shí)的大電流可能導(dǎo)致電源線上的電壓降低，從而引起對(duì)自身和其它器件的干擾。為了減少這種干擾，需要在芯片附近設(shè)置一個(gè)儲(chǔ)存電的“小水池”以提供這種瞬時(shí)大電流的能力。5、為什么去耦電容不是越大越好？答：去耦電容的去耦特性不僅跟容值有關(guān)，還跟電容的寄生參數(shù)，如等效串聯(lián)電阻、等效串聯(lián)電感、泄露電阻、介質(zhì)吸收電容、介質(zhì)吸收電阻等，這些參數(shù)同樣會(huì)影響到高頻濾波的效果。電容容值越大，寄生參數(shù)也越大。電容的諧振頻率由其等效串聯(lián)電感和容值C共同決定，這兩者的變化都會(huì)影響到電容的諧振頻率。電容在諧振點(diǎn)附近的阻抗是**低的，故設(shè)計(jì)時(shí)盡量選擇諧振頻率和實(shí)際工作頻率相近的電容為佳。通常，工作頻率變化較大時(shí)，可以選擇一些謝振頻率較低的大電容和謝振頻率較高的小電容并聯(lián)使用。6、為什么在電源的輸出端及負(fù)載電源輸入端接入電解電容的同時(shí)還要并聯(lián)高頻電容？答：在電源電路中，整流電路將交流變成脈動(dòng)的直流，而在整流電路之后接入一個(gè)較大容量的電解電容，利用其充放電特性，使整流后的脈動(dòng)直流電壓變成相對(duì)比較穩(wěn)定的直流電壓。在實(shí)際中，為了防止電路各部分供電電壓因負(fù)載變化而產(chǎn)生變化。誰在鋁電解電容工廠上過班？山東日系鋁電解電容</p><p
