  • Standard Capacitance Tolerance : +/-10% (up to +/-5% on request)
  • Maximum Current : up to 3,3 Arms at 50 Hz
  • Frequency Range : up to 100 kHz
  • Loss Factor : < 25 x 10-4 at 1kHz
  • Operating Temperature : 0°C to 45°C
  • Storage Temperature : -10°C to 50°C
  • Standard Life Time : 25 000 hours (up to 100 000 hours on request)
Applications
  • Filtering in medium power single phase rectification
  • Filtering in multi-phase rectification
