Firstly, it should be clear that,Aluminum Electrolytic capacitorIt will definitely go bad, it's just a matter of time. There are many reasons that affect the lifespan of capacitors, such as overvoltage, reverse voltage, high temperature, rapid charging and discharging, etc. Under normal use, the biggest impact is temperature, because the higher the temperature, the faster the evaporation loss of the electrolyte. It should be noted that the temperature here does not refer to the environment or surface temperature, but rather to the working temperature of the aluminum foil. Manufacturers usually label the capacitor life and testing temperature on the capacitor body.

Since the service life of the capacitor is halved every time the working temperature of the capacitor increases by 10 ℃, do not think that the aluminum Electrolytic capacitor with a service life of 2000 hours is better than that of 1000 hours. Pay attention to the test temperature to confirm the service life. Each manufacturer has calculation formulas for temperature and life, and the design of capacitance shall refer to actual data for calculation. What we need to know is that to improve the life of aluminum Electrolytic capacitor, first, we should reduce the operating temperature and keep away from heat sources on the PCB. Second, we should consider using capacitors with high maximum operating temperature. Of course, the price will also be higher.

Electrolytic capacitorThe actual voltage to be withstood in a circuit cannot exceed its withstand voltage value. In the filtering circuit, the withstand voltage value of the capacitor should not be less than 1.42 times the AC effective value. When using Electrolytic capacitor, pay attention not to connect the positive and negative poles reversely. Different types of capacitors should be selected for different circuits. Mica and high-frequency Ceramic capacitor can be selected for wiping circuit, paper dielectric, polyester, mica, electrolytic, ceramic and other capacitors can be selected for DC isolation, Electrolytic capacitor can be selected for filtering, and polyester, paper dielectric, ceramic, electrolytic and other capacitors can be selected for bypass. Before installing a capacitor into a circuit, it should be checked for any short circuits, open circuits, or leakage, and its capacitance value should be checked. When installing, make it easy to see symbols such as the type, capacity, and withstand voltage of the capacitor for verification.
