Estimating of Lifetime
Functional Polymer Aluminum Solid Electrolytic Capacitors
Calculation Formula of Lifetime
For
In general, calculation formula of lifetime of capacitors is appeared as follows.
The calculation formula of lifetime on FPCAP is same as usual Aluminum capacitor.
L X = L 0 × 10 (T 0 -T X ) /20
Where,
L X (Hrs)
L 0 (Hrs)
T 0 (105 ° C)
T X ( ° C)
=Life expectance in actual use
=Life time
=Maximum operating temperature (105 ° C)
=Temperature of capacitor in actual use
On the other hand, temperature Tx adds the circumference temperature T as the capacitor temperature and the
generating temperature Δ T by ripple current.
T X =T+ Δ T
T ( ° C) = Ambient temperature
Δ T ( ° C) = generating temperature
Furthermore, the generating temperature Δ T by the ripple current is proportional to ripple current, and is shown by the
following formula.
Δ T = ( I / I 0 ) 2 ×Δ T 0
I (A rms) = Ripple current in actual use
I 0 (A rms) = Maximum permissible ripple current
Δ T 0 ( ° C) = Generated temperature value by maximum permissible ripple current
[About 20 ( ° C) ]
