CDM Cornell Dubilier

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
