The normal lifespan of a non-solid electrolytic capacitor of consumer quality, typically rated at 2000 h/85 °C and operating at 40 °C, is roughly 6 years. It can be more than 10 years for a 1000 h/105 °C capacitor operating at 40 °C. Electrolytic capacitors that operate at a lower temperature can have a considerably longer lifespan.
|Nominal Value||105°C||2 000h||95°C||85°C|
|Real temp||95°C||4 000h||2 000h||-|
|Real temp||85°C||8 000h||4 000h||2 000h|
|Real temp||75°C||16 000h||8 000h||4 000h|

This rule characterizes the change of thermic polymer reactions speed within the specified degradation limits. According to this formula the theoretical expected service life of a 2000 h/105 °C polymer capacitor, which is operated at 65 °C, can be calculated (better estimated) with about 200,000 hours or approximately 20 years.
