Verifying that the 40 kHz rating does not exceed the peak  
voltage limitations:  
3. Ripple Current Multipliers: The “Standard and  
Extended Ratings” tables list the maximum permissible  
RMS ripple current at 40 kHz for each rating. These  
values arebased on the maximum power dissipation  
allowed at that frequency.  
Irated = 0.820 ARMS  
Ipprated= 0.820 x 2 2 = 2.32 App  
This ripple current, will cause heating, which adds to the  
ambient temperature. The higher ambient temperatures,  
voltage derating or current derating is required (see  
“Ripple Current Multipliers” tables). Also shown are the  
multipliers for ripple currents at various requencies,  
caused by the frequency dependence of the (ESR)  
equivalent series resistance. (see “Typical ESR as a  
Function of Frequency” chart)

Therefore, if the capacitor is biased between - 1.41 VDC  
and + 6.41 VDC , it can withstand the rated ripple current,  
which is based only on the maximum allowable power  
dissipation.
