U37 Series


United Chemi-Con offers their U37 series screw-terminal aluminum capacitors

The U37 family of screw-terminal aluminum electrolytic capacitors provides high ripple current and long life to extend reliability in power-inverter systems. The family has three series: U37F, U37L, and U37x. 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 with the rated ripple current applied. Its useful life is also 175,000 at 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 (μA) or 5 mA, whichever is smaller, after 5 minutes at +25°C. A 12,000 μF, 500 V capacitor has a can size of 89 x 219 mm, maximum ESR (equivalent series resistance) of 8 mΩ at +25°C and 120 Hz, and rated ripple current of 33.5 A RMS at +85°C and 120 Hz, 40.2 A RMS at +85°C and 300 Hz, and 46.9 A RMS at +85°C and >3 kHz.

Features and Benefits
  • Capacitance ranges from 1500 μF to 22,000 μF
