Thin slice.This electrolyte can evaporate during capacitor life-span, so as to change its electric attribute.If capacitor failure, its meeting
There is violent reaction:Pressure is formed in capacitor, forces it to discharge inflammable, corrosive gas.
The characteristics of aluminium electrolutic capacitor is that capacity is big, and electrochemical capacitor has point of positive and negative electrode, can not be reversed when using, but
It is that boss on the cap sequence of existing aluminium electrolutic capacitor (as shown in Figure 7) is low (as shown in Figure 5), causes vibration strength low, and
Terminal (as shown in Figure 6) is not subsidized in bottom, and (seat board of common product is all to separate with capacitor, wiring board, plays auxiliary capacitor
The not crooked effect of device), mounting stability is poor, it is impossible to meet some installation requirements, and both positive and negative polarity setup error often occurs
The problem of.
