Life Time Estimation
Lifetime Estimation of Aluminum Electrolytic Capacitors from Jianghai
To estimate the Lifetime of a non-solid Aluminum Electrolytic Capacitor from
Jianghai, the following formulas can be utilized. The
Lifetime depends mainly on the ambient temperature, the ripple current and, within certain limits, the operating voltage applied.
Other parameters may also affect the Lifetime. Moreover, L
0 can be interpreted in many different ways, which has a fundamental
influence on the numerical result.
Jianghai offers a high transparency by publishing the different typical definitions of Lifetimes in
each datasheet. Lifetime estimations are approximations by nature.
Please let
JiAnGHAi EuroPE confirm any result before using it. The formulas given here do not constitute part of a contract nor
of a specification. The formulas do not cover additional aging effects of certain electrolytic systems or other chemical effects. Please
contact us should you need Lifetime estimates for Solid Electrolyte Polymer Capacitors. Also the dimensions of the components
may have an effect. Forced cooling or other additional cooling-methods have a strong impact on the Lifetime and are not covered
by the formulas.
For the estimation and interpretation of Lifetime, a close collaboration with
JiAnGHAi EuroPE is strongly advised.

1. K
T Temperature Factor:
Aluminum Electrolytic Capacitors follow roughly the 10 K rule of Arrhenius. It is possible to estimate the
Lifetime by rule of thumb: When the operational temperature is reduced by 10 K, the Lifetime will double.
