The Ultimate in Ripple for Plug-in

Specifications

Type 450C is the 105 °C version of the Type 420C Inverter

Grade capacitor, and it is the PC-mount version of the Type

550C.Itdeliverstheripple-currentcapabilityandexceptional

life needed for motor-drive and inverter bus capacitors. It is

a signifcantly better value than comparable 105 °C snap-in

capacitors. The extended cathode foil of the 450C assures

cool operation and heat fow from the capacitor element to

the can in all orientations.

Highlights

• Better value than large 105 °C snap-in capacitors

• Especially for motor drives and UPS systems

• ESRs to 6.9 m

Ω

• Printed-circuit mounting

• Thermal-Pak™ extended cathode construction
