Capacitor lifetime depends on the materials 
Although not all applications are safety critical or mission critical, reliability is still a vital consideration for many electronic products. Making informed choices at the part selection stage can help ensure the product will perform correctly over its intended lifetime.
When choosing capacitors, properties such as volumetric efficiency, frequency stability, temperature rating or equivalent series resistance are often the primary factors that govern technology choice. In these cases, understanding factors affecting lifetime can help engineers make sure the product will deliver the required reliability.
On the other hand, a long operational life may be an essential requirement of the end product.
