1. Rated Current is for temperature rise of +40 ºC at 1–20 kHz.
2.
θcc
is core-to-case thermal resistance at 0–10 kHz. For higher frequency see Expected Lifetime Predictions.
3.
θ
ca is case-to-ambient thermal resistance for still air. For moving air see Expected Lifetime Predictions.

To use the Expected Lifetime curves calculate Va ⁄Vr and core
temperature T. Start by estimating:
Applied dc voltage Va
Ripple Current I
Ripple Frequency f
Ambient Temperature Ta
Airow speed v
Units:
A=m² T, Ta & Tc=°C
C=µF θ, θca & θcc =°C/W
ESR=mW v=m/s
f=kHz Va &Vr=Vdc
I=A
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).
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. Both are in the Ratings table but θca is for still air and
θcc is for 10 kHz or less. For frequency > 10 kHz multiply θcc
by [1+(f –10)/100], e.g., for 75 kHz multiply θcc by 1.65.
For moving air use the capacitor surface area A and airow speed
v to calculate θca = 1 ⁄[A(5+17(v+0.1)0.66)].
3. Compute Va ⁄Vr and the core temperature T.
T = Ta + I²(ESR)θ
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.
Expected Lifetime Predictions
The expected lifetime predictions assume no exposure to overvoltage transients.
Expected lifetime can be calculated for varying exposure to overvoltage transients.
As an illustration at 50 °C the expected lifetime is 100,000 h with the 24-hour Va ∕ Vr
