All Capacitors are “Audio Capacitors"  

There is an ongoing discussion within the audio engineering community about the sound quality of amplifiers concerning the audibility of signal distortions. Apparently, capacitors used for coupling and decoupling signals are suspected to be the source or at least a contributor to high-frequency distortions that influence the hearing impression.

Application Note ANP071: Aluminum Electrolytic vs. Aluminum Polymer Capacitor and how its benefits are used properly  

Aluminum polymer capacitor is a sub-form of the electrolytic capacitors. The special feature of these capacitor types is that a conductive polymer is used instead of a liquid electrolyte. This requires a special processing step, which is carried out during production. In this chemical reaction, the so-called polymerization, by heating, the still liquid monomer that has been impregnated in place of electrolyte in the separator paper is cross-linked to a solid polymer.

Application Note ANP109: Impedance Spectra of Different Capacitor Technologies  

Impedance and capacitance spectra are common representations of frequency dependent electrical properties of capacitors. The interpretation of such spectra provides a wide range of electrochemical, physical and technical relevant information and need to be separated from the ever-present measurement artifacts as well as parasitic effects.

Support Note SN008: Expected Lifetime of Aluminum Electrolytic and Aluminum Polymer Capacitor  

The life cycle of a capacitor depends on many factors of the application. An important factor is the temperature or rather thermal load, as it is responsible for the fact that internal structures age over time and the electrical properties deteriorate. This results in increased leakage current, increasing the ESR, which in turn leads to a further increase of the temperature.

Support Note SN019: Afraid of aging? The effects of time on electrolytic capacitors  

Since the development and production of electrolytic capacitors, designers have had to deal with the issues of aging and shelf life of these products. Electrolytic capacitors have been around for a very long time, but the rapid increase did not occur until the 1960s. There are still many "myths" from that time that revolve around the aging and shelf life of these capacitors.
