Type 947C Polypropylene, DC Link Capacitors
High Current, High Capacitance for Inverter Applications
Type 947C series uses the most advanced metallized film
technology for long life, high reliability in DC Link applications.
This series delivers high capacitance, high voltage and high ripple
current handling capabilities required for inverters used in wind,
solar, fuel cell applications and more.
Highlights
- Non-polar dielectric
- Dry, resin filled
- High reliability and life expectancy
- Replacement for aluminum electrolytic
capacitors (lower capacitance, higher current)
- High current to 100 Amps
- Low ESR
Specifications
- Low Inductance

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. ca 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
temperature T. Start by estimating:
Applied dc voltage Va
1. Start with the 10 kHz ESR from the Ratings table. If frequency is
less than 10 kHz, add 31.83 ⁄(fC).
Ripple Current I
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
Ripple Frequency f
Ambient Temperature Ta
Airflow speed v
Units:
by
[1+(f –10)/100], e.g., for 75 kHz multiply θcc by 1.65.
A=m²
C=µF
ESR=mW
f=kHz
I=A
T, Ta & Tc=°C
θ, θca & θcc =°C/W
v=m/s
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)].
Va &Vr=Vdc
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;
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).
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.
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
profile below:
