The lifespan of an electrolytic capacitor can vary depending on a number of factors, such as the quality of the capacitor, the temperature conditions it operates in, and the amount of use it sees. Generally speaking, high-quality electrolytic capacitors can last anywhere from 10 to 15 years, while lower quality capacitors may only last a few years.
The calculated factor in the last column is the relation between the calculated lifetime for aluminium electrolytic and aluminium polymer capacitors. In the aluminum polymer capacitor column, the calculated lifetime is 200.000 h at 65 °C ambient temperature. This means a theoretical lifetime of 22 years.
One of the main factors that affects the lifespan of electrolytic capacitors is temperature. These capacitors are designed to operate within a certain temperature range, and if they are exposed to temperatures outside of that range, they can degrade more quickly and eventually fail.
The lifespan of unused capacitors can vary depending on factors such as construction quality and storage conditions. However, in general, unused capacitors can last for several years if they are stored properly in a dry and controlled environment, away from extreme temperatures and humidity.
If the specified component temperature for aluminum electrolytic and aluminum polymer capacitors is the same (for example 2000 h at 105 °C), it can be seen at 95 °C the polymer electrolytic capacitor has a longer lifetime.
Capacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
