Film Capacitor is suited for DC filtering to 1,000 Vdc.
August 21, 2009 -
Serving DC-link inverter applications, type 945U medium-power film capacitors offer ratings up to 500 µF @ 600 V, 320 µF @ 750 V, 220 µF @ 900 V, and 160 µF @ 1,000 V. Aluminum case, which has 77 mm dia, comes in 80, 105, 131, and 156 mm heights and is electrically isolated from capacitor. Voltage/current ratings and package style allow this unit to replace aluminum electrolytic capacitors in DC Link applications that can use lower bus capacitance.
Medium Power Film Capacitor for DC Filtering to 1000 Vdc
Liberty, SC - July 2009-Cornell Dubilier announces 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.
The 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 Cornell Dubilier Electronics.
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 156 mm with ¼ -28 threaded insert terminals with an optional M12 mounting stud on the bottom.
Full specifications are at http://www.cde.com/catalogs/945U.pdf. For technical information contact Ken Thompson at (508) 996-8564. In OEM quantities Type 945U capacitors are available with pricing from $30. Samples are available upon request, production in 8-10 weeks.
