Ultra-Ripple, Long Life, Computer Grade

The Ultimate in Ripple and Life

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. (See Operating Life) Type 550C is

rated for 10,000 hours 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.
