这个品牌的如果是正品，应该不会这么弱鸡的，但是事实已经在替换中得到了正确答案，电容耐压下降了，引起高压有漏电和容量降低了。{:5_603:}当然也不排除接触不良引起的故障了。 PBX2 发表于 2023-6-30 16:06

这里有个概率问题。我家艾美特风扇买了两年电容从2.2UF下降到1UF，就是这个品牌。先入为主，我对这个品牌现在没有好感。 本帖最后由 PBX2 于 2023-6-30 16:55 编辑

哈哈！我倒是真的对这个品牌好感多多，以前的电磁炉里面都有好几个这个BM品牌的电容器，这货的品质因素那可是出奇的高！所以至今还留着好几个电磁炉上的这款电容器{:5_596:}
万用表是充电式测试，要准确上电桥 有可能 内部接触不良，内阻偏大 对电容的测试要定性，定量，需要电桥
