Aluminum (or aluminium) electrolytic capacitors have a chemical layer that has known wear-out mechanisms. Eventually, they need to be replaced. To make matters worse (or better?) there are many different options! Learn why aluminum electrolytic capacitors wear-out and how to pick their replacements in this video.
