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.

Type 947C Polypropylene, DC Link Capacitors High Current, High Capacitance for Inverter Applications 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 Airflow 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. The dielectric resistance needs to be considered for operation below 10kHz. 1. Start with the 10kHz ESR from the ratings table. If frequency is less than 10kHz, use the following equation: ESR - 31.83/(10C) + 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. For moving air use the capacitor surface area A and airflow speed v to calculate Please note that the θcc for all designs built to figures 1 and 2; 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. 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 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 profile below: Va / Vr Duration 1.67 100 ms 1.50 5 minutes 1.30 2.5 hours 1.10 9.6 hours 1.00 11.9 hours CDE Cornell Dubilier • 1605 E.
