That doesn't matter. You can apply ripple currents much larger than the cap is rated for, as long as you don't do it at such a rate that it causes the internal temperature of the cap to rise above the allowable limits.
Think of it like pushing 5 Watts of power through a resistor rated for only 1 Watt. Can you do it? The answer is YES  however, only if you limit the duration of that power level so that the AVERAGE power dissipation does not exceed the 1 Watt rating. In other words, you can dissipate 1 Watt of power through the 1Watt resistor continuously. But if you want to dissipate 5 Watts, then you can only do it for 1/5 of a second every second... or 1/10 of a second twice a second... or 1/20 of a second four times in a second.... and etc.
