Cornell Dubilier Adds High Current Power Film Caps
Hi-value capacitors.
Liberty, SC — For power electronics design engineers looking for bulk energy storage and ripple current filtering for DC link applications, Cornell Dubilier has expanded its high current power film capacitor series to include more than 120 different ratings with extended voltages up to 1300VDC and capacitance values up to 1500µF. Designated the Type 947C, the metallized polypropylene film capacitors deliver higher bus capacitance with the enhanced ripple current handling capabilities required for inverters in wind, solar and fuel cell applications connected to the power grid.

The new capacitors use advanced, metallized polypropylene film technology to provide ripple current ratings to 100A (at 55°C), with operating voltage of up to 1300VDC. Standard capacitance values range up to 1500µF at 800V; 1200µF at 900V; 970µF at 1000V; 800µF at 1100V; 600µF at 1200V; and 560µF at 1300V; with tolerances to ±10 percent and operating temperature range from -40 to +85°C. Special ratings are also available.

The aluminum cylindrical case is electrically isolated from the capacitor, and is available in 85, 90 and 116mm diameters with lengths of 85, 97, 120, 145 and 170mm, with the option of M5 or M6 threaded insert terminals, or M8 threaded stud-top terminals. Standard parts are supplied with an M12 bottom-mounting stud.
