       When choosing a smd aluminum electrolytic capacitor, if it does not exceed its rated voltage, the circuit will be smooth and its service life can be extended. Therefore, it is necessary to pay attention to the working voltage it can withstand under certain conditions. If the working voltage is exceeded, the components will be broken down, which will cause leakage or short circuit.

   When choosing a smd aluminum electrolytic capacitor, it is necessary to test whether the smd aluminum electrolytic capacitor has leakage current. It will increase as the working voltage increases. When the working voltage is close to the aluminum foil forming voltage of the anode, the leakage current will increase, so that the withstand voltage and the rated voltage under the limit situation can be calculated.

  The most widely used capacitor in electronic components are SMD aluminum electrolytic capacitor. In the process of use or when purchasing, you must pay attention to its rated voltage.
