Type 520C 85 °C Long Life, Inverter Grade, Aluminum
High Ripple, Long Life Screw Terminal 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 h 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.
Highlights
- 8,000 hour load life
- Ripple current to 55 amps
- ESRs to 8 mΩ
- Best value high ripple current
- Thermal-Pak™ extended cathode construction
