What is an electrolytic capacitor, the characteristics, working principle, common faults, and preventive measures of electrolytic capacitors 2

-Polarity: Electrolytic capacitors have polarity and must be correctly connected to the positive and negative poles.  diode

-Large volume: Under the same capacitance value, the volume is relatively large.

3. Principle: The capacitance of an electrolytic capacitor is generated by utilizing the charge distribution inside the electrolyte liquid.

4. Classification: Electrolytic capacitors can be mainly divided into two types: aluminum electrolytic capacitors and tantalum electrolytic capacitors.

5. Common faults and preventive measures:

-Electrolyte leakage: Regularly inspect the appearance of electrolytic capacitors, and replace them immediately if any leakage is found. diode

-Polarity connection error: Connect the electrolytic capacitor strictly according to its polarity to avoid damage caused by reverse connection.

-Overloading of working voltage: Avoid exceeding the maximum working voltage calibrated for electrolytic capacitors, otherwise it may damage the capacitors.
