Medium Power Film Capacitor for DC Filtering to 1000 Vdc

An excellent choice for DC link inverter applications needing lower bus capacitance, high ripple current with long life and reliability.

Liberty, SC (July 2009) — Cornell Dubilier announces the availability of Type 945U medium-power film capacitors for DC filtering. It's an excellent choice for DC link inverter applications needing lower bus capacitance, high ripple current with long life and reliability.

Type 945U's higher voltage, current ratings and package style allows it to replace aluminum electrolytic capacitors in DC Link applications that can use lower bus capacitance, as is typically the case with inverters designed for wind energy, solar and fuel cell applications supplying the grid. "The 945U uses the same package and terminal styles as screw terminal aluminum electrolytics making the transition from aluminum to film an easier one," says Ken Thompson, Product Marketing Manager at CDE.

Capacitor ratings are available up to 500µF at 600 V, 320µF at 750 V, 220µF at 900 V and 160µF at 1000 V. The aluminum case is 77mm in diameter, electrically isolated from the capacitor, in heights of 80, 105, 131 and 156mm with 1/4-28 threaded insert terminals with an optional M12 mounting stud on the bottom.

In OEM quantities, Type 945U capacitors are available with pricing from $30. Samples are available upon request, production in 8-10 weeks.
