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

Power capability is determined based on a 20°C temperature rise. A higher temperature rise and therefore higher power capability is

allowable as long as the ambient temperature plus temperature rise due to ripple current does not exceed the rated temperature of the

part.

The maximum power dissipation by case size can be determined using the below table.

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)
