Best Value High Ripple Type Plug-in
Type 420C
85 °C, Long-Life, Inverter Grade, Radial Leaded
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
