Causes and Countermeasures for Capacitor Failures: Basic Knowledge of Capacitors

Aluminum electrolytic capacitors can be used in a wide range of DC circuits! Here is an introduction to the basics of capacitors.

Aluminum electrolytic capacitors are polarized capacitors with a limited lifespan that apply electrochemical operating principles, and they are also known as chemical capacitors. These capacitors have high volumetric efficiency (capacitance per unit volume), can achieve large capacitance values in the thousands of microfarads, can withstand large ripple currents, and have high reliability, making them suitable for a wide range of applications in DC circuits. On the other hand, it is necessary to consider their relatively high leakage current compared to other capacitors, a wide capacitance tolerance range of ±20%, high equivalent series resistance, and their finite lifespan when using them. Related catalogs provide detailed information on the features and structure of aluminum electrolytic capacitors and film capacitors.
