Is higher ripple current better?
The ripple current is the amount of current passing through the cap. Higher current = more power dissipated in the cap which makes it hotter, hotter cap = shorter life. Caps rated at higher ripple current should last longer, but you will need to take several variables into consideration when comparing.
What causes ripple current?
Ripple can be caused by unwanted AC currents coming from the load side, and in this situation more ripple means more heat that must be dissipated in the capacitor. At a certain point this will cause a thermal runoff effect that will eventually cause the capacitor to fail, opening up the circuit.
How do you select a ripple current for a capacitor?
As a general rule of thumb, keeping the peak to peak ripple amplitude below 75 mV keeps the rms currents in the bulk capacitors within acceptable limits. Load current, duty cycle, and switching frequency are several factors which determine the magnitude of the input ripple voltage.
What does high ripple current capacitor mean?
Ripple current for aluminum electrolytic capacitor Some applications such as smoothing and filtering load electrolytic capacitors with AC ripple current. This ripple current causes power dissipation and heating and subjecting electrolytic capacitors to high temperatures shorten their life.

The ripple current in capacitors mainly means the current flowing into capacitors when the load current to IC changes. At this time, capacitors generate heat by the ripple current since they have resistance called ESR in themselves.
