Film capacitors are used in a wide variety of different industry, including with military technology and applications as well as the aerospace industry. This is mainly due to the fact that they have high long term stability, can be produced relatively cheaply and are heat resistant. 

One of the main characteristics of our film capacitor comes from the fact that they are not polarized. Due to this design element, they are available for use in both AC power and signal applications. 

They are also designed to have high precision capacitance values, which means that they can retain their value for a much longer period of time than capacitors of other types. The aging process of these types of capacitors is generally much slower than it would be if a different type of material were being used during construction.

Aluminum electrolytic capacitors, also commonly known as just electrolytic capacitors, are a unique type of configuration that uses an electrolyte to achieve a capacitance that is much larger than other types of these devices. The electrolyte in question is usually either a gel or a liquid that itself contains a very high concentration of polarized ions. Polarization indicates that the voltage on the positive terminal is always larger than the similar voltage on the negative terminal of the capacitor.

One of the major benefits of these types of aluminum electrolytic capacitors is the aforementioned large capacitance. They do, however, have a number of disadvantages when compared to other types of capacitors. Aluminum electrolytic capacitors have a large leakage current when compared to capacitors of other types. Additional disadvantages include a limited lifetime, value tolerances and an equivalent resistance series.
