【DESCRIPTION】：
If the capacitance capacity is very small, the withstand voltage is very high, and the working voltage is low, nothing can be seen from the reverse connection; if the capacity is slightly large (above 100uF), the withstand voltage is close to the working voltage, and the capacitance will not be damaged for more than 10 minutes, the bad form is: first bulge, then blow, and then burst.
The reverse connection of polar capacitor will explode, doesn't it mean that it can't be directly connected to the AC power supply?
It can't be connected to the AC power supply, because this polar capacitor design is used in the DC power supply for filtering. I used to ask this question for a long time, and have been asking, "isn't the capacitor separated from the direct AC, how can a polar capacitor not be used in the AC power supply?" Because there is a special material inside the polar capacitor, which can't bear the back pressure. If it is connected to the alternating current, it will reverse breakdown or explode.
The polarity capacitance cannot be reversed. Why is the negative half cycle of AC allowed to pass?
Under certain conditions, AC signal can regard capacitance as short circuit. How to solve the negative half cycle of AC signal? Do you want to pull it up to DC?
The AC signal must be carried on the DC current, which is to be pulled up to DC!
When a polar capacitor is working, the positive potential must be higher than the negative. Otherwise, the leakage of the capacitor ---- if it is light, the circuit will not work, if it is heavy, the capacitor will explode.
Shenzhen CAPSUN Electronic Co., Ltd. the newly developed non-polar capacitor can be free from the influence of polarity. For more details, please consult the Engineer
