To use the Expected Lifetime curves calculate Va ⁄Vr and core
temperature T. Start by estimating:
Units:
NOTE: The temperature rise in the 947C is I²(ESR) times the
thermal resistance θ. The ESR is mainly the metal resistance;
the metal resistance is the 10 kHz ESR. For operation below 10
kHz add the dielectric resistance. It is the dielectric dissipation
factor—no more than 0.0002—times the capacitive reactance,
i.e., 0.0002 ⁄(2πfC). That’s equal to 31.83 ⁄(fC).

As an illustration at 50 °C the expected lifetime is 100,000 h with the 24-hour Va ∕ Vr.
Expected lifetime can be calculated for varying exposure to overvoltage transients.
Expected Lifetime vs Core Temperature and Applied DC Voltage

The expected lifetime predictions assume no exposure to overvoltage transients.

1. Start with the 10 kHz ESR from the Ratings table. If frequency is
less than 10 kHz, add 31.83 ⁄(fC).
2. Compute total thermal resistance θ as the sum of core-to-case
thermal resistance θcc and case-to-ambient thermal resistance
θca.
θcc is for 10 kHz or less. For frequency > 10 kHz multiply θcc
by
For moving air use the capacitor surface area A and airflow speed
v to calculate θca = 1 ⁄[A(5+17(v+0.1)
3. Compute Va ⁄Vr and the core temperature T.
4. Look up estimated lifetime from the Expected Lifetime curves.
5. If you want a longer expected lifetime, choose a capacitor with
higher voltage rating or consider using multiple capacitors in
parallel to share the ripple current.
