Type 550C 105 °C High Ripple, Inverter Grade, Aluminum
Ultra-Ripple, Long Life Screw Terminal Type
Type 550C is the standard for motor drive and other high-ripple, long-
life applications. It boasts more than 25% extra ripple capability per
can size, but less capacitance than Type 520C. Expected operating
life is more than 100,000 hours in typical applications. Type 550C is
rated for 10,000 h life with full ripple current, rated voltage, 85 ºC and
100 lfm airflow while mounted horizontally. Horizontal mounting is
more severe than vertical mounting. The extended cathode foil of the
550C assures heat flow from the capacitor element to the can in all
orientations.
