Type 947C High Capacitance, High Current, DC Link Capacitors
Metallized Polypropylene Dielectric
Type 947C series uses the most advanced metallized
film technology for long life, high reliability in DC
link applications. Their high-voltage and high-current
ratings allow for replacement of series-parallel banks of
aluminum electrolytic capacitors in high ripple current
applications.

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. θca is case-to-ambient thermal resistance for still air. For moving air see Expected Lifetime Predictions.

Expected Lifetime Predictions
To use the Expected Lifetime curves calculate Va ⁄Vr and core 1. Start with the 10 kHz ESR from the Ratings table. If frequency is
temperature T. Start by estimating:
Applied dc voltage Va
Ripple Current I
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 airflow 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
NOTE: The temperature rise in the 947C is I²(ESR) times the
thermal resistance θ. The ESR is mainly the metal resistance; 4. Look up estimated lifetime from the Expected Lifetime curves.
the metal resistance is the 10 kHz ESR. For operation below 10
kHz add the dielectric resistance. It is the dielectric dissipation 5. If you want a longer expected lifetime, choose a capacitor with
factor—no more than 0.0002—times the capacitive reactance, higher voltage rating or consider using multiple capacitors in parallel
i.e., 0.0002 ⁄(2πfC). That’s equal to 31.83 ⁄(fC).
