Technical data and specifications Characteristics Rated capacitance CN Up to 3900µF ( see table ) Tolerance K (±10%), other tolerances available up on request. Rated voltage range UN 1100 to 2300V (see table) Operation bandwidth (*) Up to 50KHz Rated current IR (1 kHz) (see table) Inductance Le Ca. 14 nH Rth (**) Construction A: 1.4 K/W Construction B: 2 K/W (*) RMS current value that corresponds to components above 50kHz limited to 10% of total RMS. Maximum continuous losses defined for rated current at 1kHz should not be exceed. ESR vs frequency graphs available in page 5 for losses calculation according to a specific current spectrum. For more accurate thermal calculation, please ask for FEA simulation according to your specific operation conditions. (**) Calculated from Tamb to Thot-Spot considering natural convection and no transfer of heat through the terminals. For more accurate thermal calculation, please ask for FEA simulation according to your specific operation conditions.
