Extended high current power film capacitor series from CDE for inverter apps

Cornell Dubilier (CDE) has extended its high current power film capacitor series with the release of a Type 947C, a new metallized polypropylene film capacitors that delivers high capacitance, high voltage and high ripple current handling capabilities required for inverters used in wind, solar, fuel cell applications.

The new capacitor series to include more than 120 different ratings with extended voltages up to 1300 Vdc and capacitance values up to 1500 µF.

The key features of the Type 947C capacitor series are,

Non-polar dielectric
Dry, resin filled
High reliability and life expectancy
Replacement for aluminum electrolytic capacitors (low capacitance, high current)
High current to 100 Amps
Low ESR and Inductance

"The extended voltage ratings and case sizes provide design engineers with more options for power film capacitors in inverter applications where higher ripple current ratings are required," said Laird Macomber, technology manager at Cornell Dubilier. "These higher voltage and current ratings eliminate the need for multiple aluminum electrolytics across the bus and greatly improve reliability and lower cost."

Operating temperature range: -40 ºC to 85 ºC

Price: Starts at each $35 in OEM quantities
