Ripple Current/Ripple Voltage
Permissible AC ripple voltage and current are related to equivalent
series resistance (ESR) and the power dissipation capabilities of
the device. Permissible AC ripple voltage which may be applied is
limited by two criteria:
1. The positive peak AC voltage plus the DC bias voltage, if any,
must not exceed the DC voltage rating of the capacitor.
2. The negative peak AC voltage in combination with bias
voltage, if any, must not exceed the allowable limits specified for
reverse voltage. See the Reverse Voltage section for allowable
limits.
The maximum power dissipation by case size can be determined
using the table at right. The maximum power dissipation rating
stated in the table must be reduced with increasing environmental
operating temperatures. Refer to the table below for temperature
compensation requirements.

Temperature Compensation Multipliers
for Maximum Power Dissipation
T ≤ 25°C T ≤ 85°C T ≤ 125°C
The maximum power dissipation rating must be reduced with increasing
environmental operating temperatures. Refer to the Temperature Compensation
Multiplier table for details.

T= Environmental Temperature
Using the P max of the device, the maximum allowable rms ripple
current or voltage may be determined.
I(max) = √ P max/R
E(max) = Z √ P max/R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)
P max = maximum power dissipation (watts)
R = ESR at specified frequency (ohms)
Z = Impedance at specified frequency (ohms)
