參數(shù)一:電容值
電容值C=Q/U。
要計(jì)算主板CPU供電部位對電容容量的需求,使用如下公式:
C = I/(∆V/∆t)
假如CPU的電流I為50A, ∆V=50mV時(shí),∆t=10μS。則容量要求為C=10000μf。要得到理想的濾波效果的話,就要求要7顆1500μf的電容并聯(lián)使用。
參數(shù)二:耐壓值
耐壓值是表示電容+/-極之間的壓差,如果出現(xiàn)過壓現(xiàn)象,電容就會處于擊穿狀態(tài),漏電流增大,電容內(nèi)部發(fā)熱巨增,電容內(nèi)部的電解液會因高溫變成氣體致使電容內(nèi)部壓力增大。當(dāng)這個(gè)壓力超過電解電容的鋁外殼承受壓力的時(shí)候,電容就會發(fā)生。CPU的工作電壓一般在1~2V之間,電容耐壓能在4V以上就一般不會出問題,前提是電容極性不得插反!
