Derating Guidelines
V
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:
The maximum power dissipation by case size can be determined using the below left table. The maximum power dissipation rating
stated in the table must be reduced with increasing environmental operating temperatures. Please refer to the below right table for
temperature compensation requirements.

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.

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) = √P max * R
I = rms ripple current (amperes)
E = rms ripple voltage (volts)
Pmax = maximum power dissipation (watts)
