Aluminum electrolytic capacitor storage

Hello @kesadav882,

Please see the engineering notes and FAQ in this post:

Selection Guide for Aluminum Electrolytic Capacitors

What is an aluminum electrolytic capacitor? Capacitors are passive electronic devices that store electric charge. Polarized aluminum electrolytic capacitors are typically constructed using two rolled layers of aluminum foil separated by a paper insulator saturated with a wet electrolyte. This capacitor’s dielectric consists of this insulator in conjunction with a thin oxide layer formed on the positive foil anode. Electrolytic capacitors have a relatively high capacitance-voltage (CV) rating per…

Why do electronic components have a shelf life?

Electronic component manufacturing is a miracle of modern technology. It’s a fascinating and highly complex process to extract the raw materials from the earth, purify them, and then produce the finished products. Millions of man hours have been expended to manufacture materials that are low in cost, easy for the end user to assemble, and electrically plus mechanically stable. This is true for all components from the “simple” resistor all the way to the most complex multicore processor. Despite…

It applies to all capacitors for today and 100 years into the past.

Sincerely,

Aaron

P.S. Why do you keep asking the same questions about aging electronic? As I’ve told you too many times already, things degrade. It’s the nature of the technology and economics that balance cost, features, and longevity.
