■ Calculation Formula
The life of aluminum electrolytic capacitors is highly
affected by applied ripple current and ambient
temperature. In general, the relation between life time,
ripple current, and ambient temperature is known as: ••
Where:
I: Ripple current to be applied to the capacitor T°C
(120 Hz… [A rms]
I
P
: Specified maximum permissible ripple current at 120
Hz, +85°C… [A rms]
L: Expected life at T°C… [h]
L
0
: Specified life (series TS-U: 2,000 hours)… [h]
T: Ambient temperature [°C]
T
0
: Hot spot temperature in the capacitor element =
[maximum operating temperature] + [∆t at maximum
ambient temperature] = [maximum temperature
(series TS-U: +90·C)]… [°C]
∆t: Temperature rise at constant current flow of
maximum permissible ripple current value specified
at +85°C (see graph1 ∆t vs T)… [°C]
