Cornell Dubilier has expanded its high-current power film capacitor series to include more than 120 different ratings with extended voltages up to 1300V DC and capacitance values up to
The extended voltage ratings and case sizes provide design engineers with more options for these devices in inverter applications, where high ripple current ratings are required. These high voltage and current ratings eliminate the need for multiple aluminium electrolytics across the bus and improve reliability, and lower cost.
The devices employ advanced, metallised polypropylene film technology to provide ripple current ratings up to 100A at 55°C, with an operating voltage of up to 1300V DC. 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 up to ±10%, and an operating temperature range from -40°C to +85°C.
The aluminium cylindrical case is electrically isolated from the device, 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.
