GUIDE TO APPLICATION  
1. AC Ripple Current: Subjecting a capacitor to an AC  
voltage causes an AC current to flow through it. The  
amplitude of the current is dependent on the impedance  
of the capacitor at the frequency of the applied signal:  
There will be a point at the lower frequency and  
capacitance values when the peak AC voltage will be the  
limiting factor on the ripple current - not its heating  
effects.  
For example:  
V
Z
---  
I =  
Given a 25 μF, 8 V capacitor in the “C” case code and  
assuming a ripple current application at a frequency of  
120 Hz, the total maximum allowable peak to peak  
voltage at + 25 °C is:  
where:  
I = Ripple current  
V = Applied AC voltage  
8 VF + 3 VR = 11 Vpp  
Z = Impedance of capacitor (frequency dependent)  
In order to allow the full swing of 11 Vpp and not exceed  
rated forward or rated reverse, a DC bias of 2.5 V is  
assumed to be applied.  
This current causes heating in the capacitor because of  
I2R losses (R is the equivalent series resistance at the  
applied frequency). This heating or power dissipation, is  
one of the limiting factors of the capacitor’s ripple current  
rating.  
From the ”Standard Ratings Table”, the maximum ripple  
current at 40 kHz is 0.820 A. Compensating for the lower  
frequency from the “Ripple Current Multipliers” tables:  
MAXIMUM PERMISSIBLE  
IRMS (120 Hz) = 0.820 A x 0.6 = 0.492 ARMS  
CASE CODE  
POWER DISSIPATION  
AT + 25 °C (W) IN FREE AIR  
This current rating is calculated strictly on the basis of  
maximum power dissipation. Now calculate what  
impressed voltage this amount of current will cause  
across this capacitor.

Assuming a sinusoidal voltage, calculate the rated peak  
to peak current:  
These power dissipation ratings are based on a  
calculated + 50 °C internal temperature rise in still air. The  
maximum allowable ripple currents given in the Standard  
and Extended Ratings tables are based on these ratings  
and the maximum equivalent series resistance at that  
frequency.

where:

P is in W  
I is in ARMS  
Therefore, the peak voltage of the capacitor is the limiting  
factor for the ripple current and can be calculated as  
follows:  
2. AC Ripple Voltage: In operation, the peak voltage across  
the capacitor (DC working voltage plus peak ripple  
voltage) must not exceed the rated working voltage of the  
capacitor. The DC component of the applied voltage  
should be sufficiently large to prevent polarity reversal in  
excess of 3 V at + 85 °C or 2 V at 125 °C.
