859219 Hi. At the photo you may see a small dent on the aluminum shell of a run capacitor type cbb65 (metalized polypropylene film capacitor/"self healing"). The dented aluminum shell is probably squishing the insulator (PP) and the metal film inside. My questions are:how will this condition affect the capacitor function now or in the future?
Aluminum electrolytic capacitors are (usually) polarized electrolytic capacitors whose anode electrode (+) is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of aluminum oxide by anodization that acts as the dielectric of the capacitor.
One reason could be the following: During the operation of an aluminum electrolytic capacitor with non-solid electrolyte, there is a small quantity of hydrogen developed in the component. Under nor-mal conditions, this gas permeates easily out of the capacitor.
The equivalent series resistance of aluminum electrolytic capacitors varies with the frequency of the AC signal. As a result, the ripple current capability, which is determined by the induced power loss, is also a function of the frequency.
The dielectric layer of an aluminum electrolytic capacitor is created by anodic oxidation (forming) to build up an aluminum oxide layer on the foil. The layer thickness increases in proportion to the form-ing voltage at a rate of approximately 1.2 nm/V.
The tan δ of an aluminum electrolytic capacitor is larger than other types such as film capacitors, and heat generates inside electrolytic capacitors due to power loss when ripple current is applied. Heat generation effects the life of the capacitor significantly because it causes temperature rise.
The anode of an aluminum electrolytic capacitor is an aluminum foil of extreme purity. The effec-tive surface area of this foil is greatly enlarged (by a factor of up to 200) by electrochemical etch-ing in order to achieve the maximum possible capacitance values.

Aluminum electrolytic capacitors use an electrolytic process to form the dielectric. Wet electrolytic capacitors have a moist electrolyte. Dry or solid electrolytic capacitors do not. There are two basic configurations or form factors for aluminum electrolytic capacitors: leaded and surface mount.
