电容选型4大重要指标:①容量:电容的容量,即储存电荷的容量。容量的基本单位为法拉(F),不过在主板上我们常见的是微法(μF)、皮法(pF)等单位(换算关系为1法拉=1000000微法,1微法=1000纳法=1000000皮法)。容量都是直接标出的,如GSC4700μF,一般来说该指标是越大越好。②耐压值:它是指在额定温度范围内电容能长时间可靠工作的最大直流电压或最大交流电压的有效值,不同电容...

普通铝电解电容的ESR参数厂家一般都有各种系列的电解电容,低ESR的,长寿命的,高温的。而标准品是性能最低的,或者是最便宜的,一般温度和寿命参数是85℃/105℃-1000h/2000h。我这里说的也是这种铝电解电容。损耗角正切值是有功功率与无功功率之比,在频率低的时候,比如120Hz,感抗可以忽略,因此可得到损耗角公式:普通铝电解电容在规格书中都是找不到ESR的值,但是有损耗角损耗角参数,...
