Large Can Capacitors from United Chemi-Con
Rosemont, IL — United Chemi-Con's new U-37 family of screw terminal aluminum electrolytic capacitors is offered in capacitance ranges of from 1500µF to 22,000µF, while providing high ripple current and long life to extend reliability in power-inverter systems.
The U-37 family consists of 3 series: the U37F has an endurance rating of 5,000 hours at +85°C with the rated ripple current applied. Useful life can exceed 150,000 hours at 45°C and 1.5 times the ripple current. The U37L has an endurance rating of 10,000 hours at 85°C with the rated ripple current applied. Useful life is 175,000 hours at +45°C and 1.5 times the ripple current. The U37X has an endurance rating of 15,000 hours at 85°C with the rated ripple current applied. Its useful life is also 175,000 hours at 45°C and 1.5 times the ripple current applied. Other specifications for the U37 family include voltage ratings from 350 to 500VDC, and leakage current of 0.02 CV (µA) or 5mA, whichever is smaller, after 5 minutes at +25°C. A 12,000µF, 500V capacitor has a can size of 89 x 219mm (3.5 x 8.6-in.) and rated ripple current of 33.5A rms at +85°C and 120Hz, 40.2A rms at +85°C and 300Hz, and 46.9A rms at +85°C and 3kHz.
