(see table)

8 nH

Thermal Resistance R_th

1.4 K/W

1) RMS current value that corresponds to components above 100 kHz limited to 10% of total RMS. Maximum continuous losses defined for

rated current at 3 kHz should not be exceed. ESR vs frequency graph 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.

2) Connecting all independent capacitances by external overlapped busbar as described in page 4.

3) Calculated from T_ambto T Thot-Spot considering natural convection and no transfer of heat through the terminals.

Maximum ratings

Maximum permissible voltage (U_max

)

UN +10% (30% of on-load daily duration)

U^N+15% (up to 30 min daily)

U^N+20% (up to 5 min daily)

U^N+30% (up to 1 min daily)

Maximum permissible peak voltage

UN +50% for 30 ms is permitted 1000 times during the lifetime

of the capacitors

UTC (Isolation)

UTC (Extinction)

4 kV

2.5 kV (<10pC)

The average applied voltage shall not be higher than the specified voltage.

It should be recognised that any significant period of operation at voltages above the rated one would reduce overall life.
