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.
