There are two kinds of capacitors that are commonly used, Aluminum Electrolytic and Conductive Polymer Aluminum Solid Capacitors. Understanding the characteristic of both capacitors is essential before making a choice. Table 1. shows the comparison of Aluminum Electrolytic Capacitor and Conductive Polymer Aluminum Solid Capacitor.
Obviously, Aluminum Solid Capacitor has more advantages. However, taking cost and high voltage withstand ability into consideration; only part of the designer will implement Aluminum Solid Capacitor when there is a demand for compact size and long life cycle.
Aluminum Electrolytic Capacitor is widely used in the rectifier circuits due to the huge capacity and lower price. However, heating will accelerate the consumption of electrolyte, which can lead to electrolyte ebullition and even explosion.
Conductive Polymer Aluminum Solid Capacitors which is one of the high-end capacitors besides tantalum electrolytic capacitor, consisting of high conductive polymer, electrolyte powders. Electrolyte powders possess the advantages of explosion-proof, high stability, high reliability, high-temperature resistance and long lifecycle.
From a basic design standpoint, an XP device must be able to withstand an explosion within its enclosure. As briefly described above, escaping gas must be allowed to cool as it expands and passes through the flame paths from inside the enclosure to the outside environment.
Using Aluminum Solid Capacitor does not guarantee a long life cycle, but to choose properly according to customers’ application and operating environment. For better evaluation of the life cycle calculation, you may refer to product test report.
