Ultra-Ripple, Long-life, Inverter Grade, 85 ºC

Type 520C

85 °C Long-life, Inverter Grade, Aluminum

Best Value High Ripple Type

Type 520C is the 85 °C version of the Type 550C Inverter-

Grade capacitor. It delivers the ripple-current capability and

exceptional life needed for motor-drive bus capacitors and

approaches the performance of the 550C at lower cost. It is

rated for 8000 hours life with full ripple current, rated voltage,

85 °C and 100 lfm airﬂow while mounted horizontally.

Horizontal mounting is more severe than vertical mounting.

The extended cathode foil of the 520C assures heat ﬂow

from the capacitor element to the can in all orientations.

• 8,000 hour load life

• Ripple current to 55 amps

• ESRs to 8 mΩ

• Best value high ripple current

• Thermal-Pak™ extended cathode construction
