Type 420C is the PC-mount version of the Type 520C screw

terminal, computer grade capacitor and the 85 °C version of

the Type 450C Inverter Grade capacitor. It delivers the ripple

current capability and exceptional life needed for motor-drive

bus capacitors and approaches the performance of the 450C at

a lower cost. The extended cathode foil of the 420C assures cool

operation and heat flow from the capacitor element to the can in

all orientations.

Highlights

- For motor drives and UPS systems

- ESRs to 6.9 mΩ

- Printed-circuit mounting

- Thermal-Pak™ extended cathode construction
