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.
Applications
Inverters: >5kW Renewable Energy Inverters: Wind, Solar, Fuel Cell Aircraft Inverters: Power Supplies and Motor Drives Transportation: Electric Vehicles, Traction Industrial: Welders, Motor Drives, Elevators, and Overhead Cranes 160 µF to 730 µF ±10% 800 Vdc, 1000 Vdc, 1200 Vdc –40 ºC to +85 ºC 60 A @ +55 ºC 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 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.
