Large-Can Capacitors Deliver Long Life for Inverter Applications



USA Made In North Carolina



United Chemi-Cons new U-37 family of screw terminal aluminum electrolytic capacitors offered in capacitance ranges of from 1500uf to 22,000uf provides high ripple current and long life to extend reliability in power-inverter systems.



The family has 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 at +45°C and 1.5 times the ripple current.  The U37X has an endurance rating of 15,000 hours at 85°c withthe rated ripple current applied.  It’s useful life is also 175,000 @45°C and 1.5 times the ripple current applied.



Other specifications for the U37 family include voltage ratings from 350 VDC to 500 VDC, standard capacitance tolerance of +20%, and leakage current of 0.02 CV (uA) or 5 mA, whichever is smaller, after 5 minutes at +25°C.  A 12,000uF, 500-V capacitor has a can size of 89x219 mm, maximum ESR (equivalent series resistance) of 8 m) at +25°C and 120 Hz, and rated ripple current of 33.5 A RMS at +85°C and 120 Hz, 40.2A RMS at +85°C and 300 Hz,and 46.9 A RMS at +85°C and 3 kHz.
